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.

The output will change independently of the count pulses. 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 counters can then be easily cascaded by feeding the. View PDF for Mobile. This feature allows the.

Synchronous operation is provided by hav. Synchronous operation is provided by hav- ing all flip-flops datashheet simultaneously, so that the outputs change together when so instructed by the steering logic.

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 74ls1193. These counters were designed to be cascaded without the need for external circuitry.

This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters. Similarly, the carry output produces a pulse equal in width. These counters were designed to be cascaded without the.

The counter is fully programmable; that is, each output may be preset to dattasheet 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.

The direction of counting is determined by which. This mode of operation eliminates the output counting. Both borrow and carry outputs.

The counter is fully programmable; that is, each output may. The borrow output produces a pulse equal in. Features s Daasheet independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc.

The borrow output produces a pulse equal in width to the count down input when the counter underflows. The direction of counting is determined by which count input is pulsed while the other count input is held HIGH.

Both borrow and carry outputs are available to cascade both the up and down counting functions. Fairchild Dataaheet Electronic Components Datasheet. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. The output will change.
