Presettable 4-Bit Down

Counters

The MC14526B binary counter is constructed with MOS P–channel

and N–channel enhancement mode devices in a monolithic structure.

This device is presettable, cascadable, synchronous down counter

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 input allows cascade divide–by–N

operation with no additional gates required. The Inhibit input allows

disabling of the pulse counting function. Inhibit may also be used as a

negative edge clock.

This complementary MOS counter can be used in frequency

synthesizers, phase–locked loops, and other frequency division

applications requiring low power dissipation and/or high noise

immunity.

This device contains protection circuitry to guard against damage due to high

static voltages or electric fields. However, precautions must be taken to avoid

applications of any voltage higher than maximum rated voltages to this

Unused inputs must always be tied to an appropriate logic voltage level (e.g.,
