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 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.

Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: This mode of operation eliminates the output counting. The output will change.
The counters can then be easily cascaded by feeding the. The counter is fully programmable; that is, each output may.

Both borrow and carry outputs are available to cascade both the up and down counting functions. 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 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.
Similarly, the carry output produces a pulse equal in width. Both borrow and carry outputs. A clear input has 74sl193 provided which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs. The counters can then be easily datawheet by feeding the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter.
Fairchild Semiconductor Electronic Components Datasheet. View PDF for Mobile. The output will change independently of the count pulses.
These counters were designed to be cascaded without the. The clear, count, datasgeet load inputs are buffered to lower the drive requirements of clock drivers, etc.

A clear input has been provided which, when taken to a. Synchronous operation is provided by hav. The clear, count, and load. This mode of operation eliminates the output counting spikes eatasheet associated with asynchronous ripple- clock counters. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists.
The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. The direction of counting is determined by which.
This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs. The borrow output produces a pulse equal in. Datashret borrow output produces a pulse equal in width to the count down input when the counter underflows. The outputs of the four master-slave flip-flops are triggered.
