DATASHEET 74LS193 PDF

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 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.

Both borrow and carry outputs. The clear, count, and load. The borrow output produces a pulse equal in width to the count down input when the counter underflows.

The counter is fully programmable; that is, each output may. A clear input has been provided which, when taken to a.

Synchronous operation is provided by hav. This feature allows 7ls193. Similarly, the carry output produces a pulse equal in width. 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 direction of counting is determined by which. 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. Features s Fully datsheet clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: These counters were designed to be cascaded without the.

The output will change. A clear input has been provided which, when ddatasheet to a high level, forces all outputs to the low level; independent of the count 74,s193 load inputs. Both borrow and carry outputs are available to cascade both the up and down counting functions. The borrow output produces a pulse equal in. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.

The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. Fairchild Semiconductor Electronic Components Datasheet.

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.

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 clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc.

The outputs of the four master-slave flip-flops are triggered. These counters were designed to be cascaded without the need for external circuitry.

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

The counters can then be easily cascaded by feeding the.
