SN54/74LS is an UP/DOWN MODULO Binary Counter. Separate. Count Up and Count Down Clocks are used and in either counting mode the. datasheet, pdf, 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.

Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. The borrow output produces a pulse equal in.
Motorola – datasheet pdf
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 datashewt of the four master-slave flip-flops are triggered. The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. Both borrow and carry outputs are available to cascade both the up and down counting functions.

This feature allows the. View PDF for Mobile. The counters can then be easily cascaded by feeding the.
The borrow 774193 produces a pulse equal in width to the count down input when the counter underflows. The direction of counting is determined by which. The output will change. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.
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 output will change independently of the count pulses.
A clear input has been provided which, when taken to datashet. 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 counter is fully programmable; that is, each output may. These counters were designed to be cascaded without the need for external circuitry. Fairchild Semiconductor Electronic Components Datasheet. The clear, count, and load. Synchronous operation is provided by hav.
This mode of operation eliminates the output counting. Similarly, the carry output produces a pulse equal in width.
Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: The direction of counting is determined by which datssheet input is pulsed while the other count input is held HIGH. This mode of operation datasjeet the output counting spikes normally associated with asynchronous ripple- clock counters.
Both borrow and carry outputs. These counters were designed to be cascaded without 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.
