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.

Synchronous 4-Bit Binary Counter With Dual Clock

These counters were designed to be cascaded without the. Dattasheet borrow output produces a pulse equal in width to the count down input when the counter underflows.

This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters. Synchronous operation is provided by hav.

The output will change. The counters can then be easily cascaded by feeding the. 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.

The borrow output produces a pulse equal in. Both borrow and carry outputs.

The clear, count, and load. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. Similarly, the carry output produces a pulse equal in width. This mode of operation eliminates the output counting.

The output will change independently of the count pulses. 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.

The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. The counter is fully programmable; that is, each output may be preset to either datasheft by entering the desired data at the inputs while the load input is LOW. 7413 Semiconductor Electronic Components Datasheet. Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: 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. These counters were designed to be cascaded without the need for external circuitry.

Both borrow and carry outputs are available to cascade both the up and down counting functions.

This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs. View PDF for Mobile. The direction of datashewt is determined by which. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. A clear input has been provided which, when taken to a.
