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. Fairchild Datahseet Electronic Components Datasheet. Synchronous operation is provided by hav. This mode of operation eliminates the output counting spikes normally associated with asynchronous ripple- clock counters. The borrow output produces a pulse equal in width to the count down input when the counter underflows. This mode datasheer operation eliminates the output counting. This feature allows the counters to be used as modulo-N dividers by simply modi- fying the count length with the preset inputs.

The direction of counting is determined by which. A clear input has been provided which, when taken to a. The clear, count, and load.

Both borrow and carry outputs are available to cascade both the up and down counting functions. A clear input has been datashwet which, when taken to a high level, forces all outputs to the low level; independent of the count and load inputs.

The direction of counting is determined by which. The counters can datssheet be easily cascaded by feeding the borrow and carry outputs to the count down and count up inputs respectively of the succeeding counter. The borrow output produces a pulse equal in. The counters can then be easily cascaded by feeding the. Both borrow and carry outputs.

Features s Fully independent clear input s Synchronous operation s Cascading circuitry provided internally s Individual preset each flip-flop Ordering Code: Similarly, the carry output produces a pulse equal in width.

A clear input has been provided which, when taken to a. The output will change independently of the count pulses. A clear input has been provided which, when taken to a high level, forces all outputs to the datasueet 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. These counters were designed to be cascaded without the need for external circuitry.

Similarly, the carry output produces a pulse equal in width. 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 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- fying the count length with the preset datashret. The counter is fully programmable; that is, each output may.

The output will change independently of the count pulses. Synchronous operation is provided by hav. 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. This feature allows the. The clear, count, and load inputs are buffered to lower dwtasheet drive requirements of clock drivers, etc.

These counters were designed to be cascaded without the need for external circuitry. The borrow output produces a pulse equal in. Both borrow and carry outputs.
