MC14522B - Presettable 4-Bit Down Counters

Preset Enable (Pin 3) * If Reset is low, a high level on the Preset Enable input asynchronously loads the counter with the programmed values on P0, P1, P2, and P3.

Inhibit (Pin 4) * A high level on the Inhibit input pre * vents the Clock from decrementing the counter.

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Presettable 4-Bit Down Counters The MC14522B BCD counter and the MC14526B binary counter are constructed with MOS P channel and N channel enhancement mode devices in a monolithic structure.

These devices are presettable, cascadable, synchronous down counters with a decoded “0” state output for divide by N applications.

In single stage applications the “0” output is applied to the Preset Enable input.

The Cascade Feedback inp
