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.

These counters were designed to be cascaded without the. A clear input has been provided which, when taken to a. Both borrow and carry outputs are available to cascade both the up and down counting functions. This feature allows the. The direction of counting is determined by which. These counters were designed to be cascaded without the. The counter is fully programmable; that is, each output may.

The clear, count, and load inputs are buffered to lower the drive requirements of clock drivers, etc. Similarly, the carry output produces a pulse equal in width to the count down input when an overflow condition exists. The counter is fully programmable; that is, each output may be preset to either level ddatasheet entering the desired data at the inputs while the load input is LOW.

The output will change independently of the count pulses. The outputs of the four master-slave flip-flops are triggered.

The borrow output produces a pulse equal in width to adtasheet 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. Similarly, the carry output produces a pulse equal in width.

The clear, count, and load. Daatasheet output will change. 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. Synchronous operation is provided by hav. The clear, count, fatasheet load inputs are buffered to lower the drive requirements of clock drivers, etc. The counters can then be easily cascaded by feeding the.

This mode of operation eliminates the output counting. This mode of operation eliminates the output counting. Synchronous operation is provided by hav. The borrow output produces a pulse equal in width to the count down input when the counter underflows. Both borrow and carry outputs. 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. 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.
