They do not wash out in sunlight, although their reliability diminishes with the higher currents required in brightly lighted applications. Routinely, finished samples are subjected to all electrical performance tests.

To insure proper opera- tion, resistor R should be used as shown in the typical application. The decoder automati- cally switches between stereo and monaural opera- tion by detection and evaluation of the kHz pilot carrier signal.

Test samples are taken at ran- dom from each lot and are subjected to testing for performance evaluation and specification com- pliance. Of particular interest in this application is Type ULNA input current level is specified at an unusual use of the transient-suppression diodes for 1. This is a general-purpose version with input current limiting normally accomplished via the use of an appropriate discrete resistor connected in series with each input. Its outstanding fea- ture is that only a single low-cost tuned circuit is re- quired instead of the previous triple-winding trans- former.

Some of the gas display manufacturers recommend the use of series resistors in each segment line to prevent destruction to the semiconductor in- terface circuit should such a panel arc occur.

Type UDNA is a high-current source driver used to switch the ground ends of loads that are directly connected to a negative supply. Units Supply Voltage Vqq 4. By utilizing a negative supply, the level shifting is easily done in the cathode side.

Panel technologies using thick or thin-film techniques could benefit from such an approach. Minimum data pulse width. Lower package costs are necessary to further increase the use of ICs in areas such as flat panel matrix displays. Applications The UHC- and UHD- Series, and power and relay drivers are ideally suited for driving incandescent lamps, relays, solenoids, and other interface devices with up to 1 A output current per package.


Without a standard I L logic family, the main market penetration would appear to be custom designs although there is a definite opportunity for standard interface for lower voltage applications, particularly LEDs and vacuum fluorescent.

In A-M operation, stability is seldom a pro- blem. Our direction was determined by two factors: All eight of these devices include integral transient suppression diodes for use with inductive loads. Sprague Electric assumes no obligation for future manufacture of any products presently in development unless such obligation is specifically undertaken in writing by authorized Sprague personnel.

Printed wiring board real estate is increasingly dictating smaller size. Input signals to the four-bit device, for both unipolar wave drive and unipolar two-phase drive, are shown in Figures 3 and 4. It gives maximum gain without common-mode interference and noise. The high-gain, high-impedance operational amplifier configuration allows many specialized input, output, and feedback arrangements.

Sustaining this instantaneous inrush current and its peak power has been a key element in the success of many lamp interface circuits. They tend to simplify certain system designs while offering size and cost reductions.

A simple d-c switch is used to change mode of operation. This monolithic integrated circuit excels lm1391 signal-seeking and scanning applications. The a-m mixer is a fully-balanced mixer based on a four-quadrant multiplier as shown in Figure 7.

The substrate must be tied to the most negative point in the external circuit to maintain isolation between drivers and to provide for normal circuit operation. It increases with lower values of loaded Q and lower values of resistance between pins 7 and Minimum data active time after strobe disabled data hold time ns C.

Using the circuitry shown, a typical recovered audio value of millivolts at Pin 8 and total harmonic distortion value of 0. Signal level shifting is inexpensively accomplished with capacitors; the OFF reference, pull-up, and pull- down is done with a few discretes. All input connec- tions are on one side of the package, output connec- tions on the other, for simplified layout of printed wiring boards. This is implemented in the ULN- resulting in the waveform shown.

Balanced operation of the mixer provides typically 25 dB of I-F rejection at the input, with a similar rejection of the associated noise passband. Other combinations of number of outputs con- ducting and duty cycle are shown in the specifica- tions. DI interface, with its potential for V transistors, has a great promise if the barriers can be overcome. Type ULXA provides all high-frequency circuitry, including AGC and envelope peak detection, for a single- conversion superheterodyne broadcast or shortwave receiver.


All semiconductor wafer fabrication is done in the Worcester plant, as are all services integral to its support. Mute bandwidth decreases with higher values of loaded Q and higher values of resistance between pins 7 and To order, change the last letter of the part number from A’ to R’. A combination of high- voltage bipolar techniques with thin-film resistor technology circuit resistors sputtered over the IC dielectric has provided both digit anode and segment cathode interface.

An increased awareness for improvements in reliability and space and power reductions provided a rather successful military market for Sprague lamp and relay interface; early success was evident in military aircraft indicator lamp interface, a tough application for TTL type ICs due to severe inrush currents resulting in secondary breakdown during “turn on”. Without this condition- ing, marginal circuits that initially meet all specifications could exhibit early lifetime failures under normal operating condi- tions.

Additional features include emitter-follower out- puts for driving low impedance loads and a voltage regulator for increased stability. Dependent on value of external current limiting resistor, 13 V at 0Q. A d-c switch is used to change modes. Units Supply Voltage, V C c 4. The following IC Technology-Display Interface matrix lists the key characteristics and primary display applications of various semiconductor technologies. Creation of sourcing functions Figures 2 and 3 ; useful for LED, gas-discharge, vacuum fluorescent, incandescent, and electromagnetic displays, depending upon device ratings.

Compounding this problem would be the effect that a high drive current requirement would have on the logic output voltage since that is normally specified at only m A.

The use of an analog multiplier as a balanced low-current mixer results in freedom from spurious responses, high tweet rejection, low feedthrough I-F rejectionand low noise, as well as very low local oscillator radiation.

Internal tran- sient suppression is built into both.
