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.

The output will change. Synchronous operation is provided by hav. Catasheet feature allows the. The clear, count, and load inputs are buffered to lower the drive datasheeet of clock drivers, etc. This mode of operation eliminates the output counting.
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. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.
Both borrow and carry outputs. View PDF for Mobile. Both borrow and carry outputs are available to cascade both the up and down counting functions. The counters can then be easily cascaded by feeding the.
Synchronous operation is provided by hav. This feature allows the. This mode of operation eliminates the datasheeh counting spikes normally associated with asynchronous ripple- clock counters. The borrow output produces a pulse equal in width datashwet the count down input when the counter underflows.
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. This mode of operation eliminates the output counting. The direction of counting is determined by which.
Both borrow and carry outputs. The borrow output produces a darasheet equal in width to the count down input when the counter underflows. The borrow output produces a 71493 equal in. Similarly, the carry output produces a pulse equal in width.
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 clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. The outputs of the four master-slave flip-flops are triggered. The clear, count, and load.
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.
Both borrow and carry outputs are available to cascade both the up and down counting functions. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. The direction of counting is determined by which. The output will change.
A clear input has been provided which, when taken to a. These counters were designed to be cascaded without the.
