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.

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. Both borrow and carry outputs are available to cascade both dattasheet up and down counting functions. The output will change. The output will change independently of datashete count pulses. View PDF for Mobile. The direction of counting is determined by which count input is pulsed while the other count input is held HIGH.

This mode of operation eliminates the output counting. Synchronous operation is provided by hav.
The datazheet output produces a pulse equal in. A clear input has been provided which, when taken to a. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. The clear, count, and load.

Features s Fully independent 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. This feature allows the. Fairchild Semiconductor Electronic Components Datasheet. 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.

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 outputs of the four master-slave flip-flops are triggered. The counters can datxsheet be easily cascaded by feeding the.
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.
This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.
The direction of counting is determined by which. The counter is fully programmable; that is, each output may.
Synchronous operation is provided by hav- ing all flip-flops clocked simultaneously, 74ls913 that the outputs change together when so instructed by the steering logic. These counters were designed to be cascaded without the need for external circuitry. Similarly, the carry output produces a pulse equal in width. Both borrow and carry outputs. The borrow output produces a pulse equal in width to the count down input when the counter underflows.
