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.

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. The direction of counting is determined by which. The output will change.

The borrow output produces a pulse equal in width to the count down input when the counter underflows. Synchronous operation is provided by hav- ing all datashewt clocked simultaneously, so that the outputs change together when so instructed by the steering logic.

Similarly, the carry output produces a pulse dstasheet in width. The direction of counting is determined by which count input is pulsed while the other count input is held HIGH. The borrow output produces a pulse equal in.

74193 Datasheet

Fairchild Semiconductor Electronic Components Datasheet. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs. 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 outputs of the four master-slave flip-flops are triggered.

These counters were designed datashedt be cascaded without the.

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.

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. Both borrow and carry outputs are available to cascade both the up and down counting functions.

A clear input has been provided which, when taken to a. 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 a. Features s Fully dataheet clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: 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.

Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. 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.

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 counters can then be easily cascaded by feeding the. 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 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 ratasheet count pulses. Datashret borrow and carry outputs.

The outputs of the four master-slave flip-flops are triggered. Fairchild Semiconductor Electronic Components Datasheet. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. This mode of operation eliminates the output counting. The counters can then be easily cascaded by feeding the.
