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.

This mode of operation eliminates the output counting. Synchronous operation is provided by hav. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.

A clear input has been provided which, when taken to a. The clear, count, and load.

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. These counters were designed to be cascaded without the.

The counter is fully programmable; that is, dattasheet output may. Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: The outputs of the four master-slave flip-flops are triggered.

The clear, count, and load datasyeet are buffered to lower the drive requirements of clock drivers, etc. The counters can then be easily cascaded by feeding the.

Both borrow and carry outputs. Fairchild Semiconductor Electronic Components Datasheet.

The counters can then be easily cascaded by feeding the borrow and 74lls193 outputs to the count down and count up inputs respectively of the succeeding counter. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.

The output will change independently of the count pulses.

This feature allows the. These counters were designed to be cascaded without the need for external circuitry. 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. The direction of counting is determined by which. 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.

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

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