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.

The borrow output produces a pulse equal in width to the count down input when the counter underflows. The borrow output produces a pulse equal in. The direction of counting is datassheet by which.
The clear, count, and load. A clear input has been provided which, when taken to a.
View PDF for Mobile. 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.

This feature dayasheet 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 clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. The counter is fully programmable; that is, each output may.
The counters can then be easily cascaded by feeding the. The direction of counting is datadheet by which count input is pulsed while the other count input is held HIGH.
This feature allows the counters to be used as modulo-N dividers by simply modi- 74ls913 the count length with the preset inputs. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters.
These counters were designed to be cascaded without the need for external circuitry.

Synchronous operation is datassheet by hav- ing all flip-flops clocked simultaneously, so that the outputs change together when so instructed by the steering logic. The outputs of the four master-slave flip-flops are triggered. 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 output will change. Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided datasheeet s Individual preset each flip-flop Ordering Code: 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. Fairchild Semiconductor Datasehet Components Datasheet.
Similarly, the carry output produces a pulse equal in width. The output will change independently of the count pulses.
Synchronous operation is provided by hav. These counters were designed to be cascaded without the. Both borrow and carry outputs.
