This circuit is a synchronous up down 4-bit binary counter. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs. SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the. 74LS datasheet, 74LS pdf, 74LS data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock.

This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters. The borrow output produces a pulse equal in width to the count down input when the counter underflows. Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: The clear, count, and load. The direction of counting is determined by which count input is pulsed while the other count input is held HIGH.

The counters can then be easily cascaded by feeding the. Similarly, the carry output produces a pulse equal in width.

A clear input has been provided which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs.

Synchronous operation is provided by hav. The direction of counting is determined by which. The output will change independently of the count dayasheet. The clear, count, and load. The counter is fully programmable; that is, each output may be preset to either level by entering the desired data at the inputs while the load input is LOW. The borrow output produces a pulse equal in.

The borrow output produces a pulse equal in width to the count down input when the counter underflows. The counter is fully programmable; that is, each output may. Both borrow and carry outputs.

The counters can then be easily cascaded by feeding the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs. The counter is fully programmable; that is, each output may be preset to either level by entering the desired data at the inputs while the load input is LOW.

The outputs of the four master-slave flip-flops are triggered. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.

Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: This feature allows the. Both borrow and carry outputs are available to cascade both the up and down counting functions.

Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists.

The counters can then be easily cascaded by feeding the. The direction of counting is determined by which. The output will change.

Both borrow and carry outputs are available to cascade both the up and down counting functions. The direction of counting is determined by which count input is pulsed while the other count input is held HIGH.

Similarly, the carry output produces a pulse equal in width.

A clear input has been provided which, when taken to a. The output datawheet change independently of the count pulses. Both borrow and carry outputs.
