74LS193 DATASHEET PDF

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. 74LS Synchronous 4-Bit Binary Counter with Dual Clock. General Description. The DM74LS circuit is a synchronous up/down 4-bit binary counter. The DM74LS circuit is a synchronous up/down 4-bit binary counter. Synchronous operation is provided by hav- ing all flip-flops clocked simultaneously.

These counters were designed to be cascaded without the. This feature allows 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.

Fairchild Semiconductor Electronic Components Datasheet. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc.

Synchronous operation is provided by hav. The direction of counting is determined by which. A clear input has been provided which, when taken to a. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.

Datashee borrow output produces a pulse equal in. This mode of operation eliminates the output counting. The output will change. 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 output will change independently of the count pulses.

Synchronous 4-Bit Binary Counter With Dual Clock

The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. View PDF for Mobile. Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: Similarly, the carry output daasheet a pulse equal in width datawheet the count down input when an overflow condition exists. The outputs of the four master-slave flip-flops are triggered.

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 74l193 either level by entering the desired data at the inputs while the load input is LOW. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.

The counters can then be easily cascaded by feeding the. The clear, count, and load. 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.

These counters were designed to be cascaded without the need for external circuitry. The borrow output produces a pulse equal in width to the count down input when the counter underflows. Both borrow and carry outputs.

The counter is fully programmable; that is, each 74ls1993 may.
