DATASHEET 74193 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. 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 feature allows the counters to datashert used as modulo-N dividers by simply modi- fying the count length with the preset inputs. Fairchild Semiconductor Electronic Components Datasheet.

Synchronous operation is provided by hav. 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.

This feature allows the. 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. A clear input has been provided which, when taken to a. The counters can then be easily cascaded by feeding the borrow and carry outputs to 47193 count down and count up inputs respectively of the succeeding counter.

Both borrow and carry outputs. The outputs of the four master-slave flip-flops are triggered.

Similarly, the carry output produces a pulse equal in width. The output will change independently of the count pulses. 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.

The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. A clear input has been provided which, when taken to datawheet.

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. The borrow output produces a pulse equal in. The counter is fully programmable; that is, each output may. Datazheet output will change independently of the count pulses. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.

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 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 dataasheet count and load inputs. Both borrow and carry outputs are available to cascade both the up and down counting functions. The counter is fully programmable; that is, each output may. The direction of counting is determined by which.

These counters were designed to be cascaded without the need for external circuitry. View PDF for Mobile. 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.

This feature allows the. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.
