The direction of counting dwtasheet determined by which count input is pulsed while the other count input is held HIGH. 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.

Similarly, the carry output produces a pulse equal in width.

The borrow output produces a pulse equal in. The output will change independently of the count pulses.

The counters can then be easily cascaded by feeding the. These counters were designed to be cascaded without the need for external circuitry.

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 datasheer a pulse equal in width to the count down input when an overflow condition exists.
