HEF4520B counter equivalent, dual binary counter.
* Tolerant of slow clock rise and fall times
* Fully static operation
* 5 V, 10 V, and 15 V parametric ratings
* Wide supply voltage range from 3.0 V to 1.
The HEF4520B is a dual 4-bit internally synchronous binary counter with two clock inputs (nCP0 and nCP1), buffered outputs from all four bit positions (nQ0 to nQ3) and an asynchronous master reset input (nMR). The counter advances on either the LOW-t.
