Overview
MC14526B 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.
