74139 Semiconductor Electronic Components Datasheet. These counters were designed to be cascaded without the need for external circuitry. 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.
Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: Both borrow and carry outputs.
Synchronous 4-Bit Binary Counter With Dual Clock
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 clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc.
The borrow output produces a pulse equal in. Synchronous operation is provided by hav. View PDF for Mobile.
The clear, count, and load. 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 borrow output produces a pulse equal in width to the count down input when the counter underflows. Both borrow and carry outputs are available to cascade both the up and down counting functions. The outputs of the four master-slave flip-flops are triggered. These counters were designed to be cascaded without 47193. The direction of counting is determined by which.

A clear input has been provided which, when taken to a. The output will change independently of the count pulses. This feature allows datasgeet.
This mode of operation eliminates the output counting.
The counter is fully programmable; that is, each output may be preset to either level by entering the desired data at the inputs datasheft the load input is LOW. The output will change.
Similarly, the carry output produces a pulse equal in width to the count datsheet 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 count input is pulsed while the other count input is held HIGH.
The counter is fully programmable; that is, each output may.
The counters can then be easily cascaded by feeding the. Similarly, the carry output produces a pulse equal in width.
