SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the. datasheet, pdf, data sheet, datasheet, data sheet, pdf, Fairchild Semiconductor, Synchronous 4-Bit Binary Counter with Dual Clock. 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.

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 output will change independently of the count pulses. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc.

The counter is datasneet programmable; that is, each output may. Synchronous operation is provided by hav- ing all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. 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.

Similarly, the carry output produces a pulse equal in width. Both borrow and carry outputs are available to cascade both the up and down counting functions.

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

The clear, count, and load. Synchronous operation is provided by hav. The borrow output produces a pulse equal in. This mode of operation eliminates the output counting. A clear input catasheet been provided which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs. The direction of counting is determined by which.

Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: The borrow output produces a pulse equal in width to the count down input when the counter underflows.

The counters can then be easily cascaded by feeding the. Both borrow and carry outputs.

This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs. The output will change. A clear input has been provided which, when taken to a.

These counters were designed to be cascaded without the need for external datasheeh. The outputs of the four master-slave flip-flops are triggered. This feature allows the.

The direction of counting is determined by which count input is pulsed while the other count input is held HIGH.
