MOTOROLA SEMICONDUCTOR TECHNICAL DATA MC14569B Programmable Divide-By-N Dual 4-Bit Binary/BCD Down Counter The MC14569B is a programmable divide by N dual 4 bit binary or BCD down counter constructed with MOS P channel and N channel enhancement mode devices (complementary MOS) in a monolithic structure.

This device has been designed for use with the MC14568B phase comparator/counter in frequency synthesizers, phase locked loops, and other frequen
