MC14526B Presettable 4-Bit Down Counters

MC14526B Description

MC14526B Presettable 4-Bit Down Counters The MC14526B binary counter is constructed with MOS P *channel and N *channel enhancement mode .
Preset Enable (Pin 3). If Reset is low, a high level on the Preset Enable input asynchronously loads the counter with the programmed values.

MC14526B 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 nega
