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. 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.

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. 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. Similarly, the carry output produces a pulse equal in width. The counters can then be easily cascaded by feeding the. Ordering Code:. Order Number. Package Number. Package Description. Connection Diagram. AC Electrical Characteristics. From Input. To Output.

Count Up. Count Down. Either Count. Load to. Any Q. What are the advantages of implementing a synchronous counter with the 74LS circuit versus using discrete flip-flops and gates?

This is the 2-to-9 Binary Up Counter. It works according to the design and the probes show the binary count that goes into the HEX display.

Are there any disadvantages to using the 74LS integrated circuit? The thing that makes it so much better than the is that the chip has uc capacity to count both up and down.

These are the four output pins. The probes show the binary count that go into the HEX Display. For a better experience, please enable JavaScript in your browser before proceeding.

It has been bread boarded based on the Multisim design. When the DOWN pin gets a rising edge clock pulse, the flops count down by one number. Use the 74LS to create a Binary up counter. This is a Clear pin, which will instantly reset all the outputs to LOW, or 0. After you have made the circuit modify the circuit to count from E.
