MOTOROLA SEMICONDUCTOR TECHNICAL DATA Phase Comparator and Programmable Counters The MC14568B consists of a phase comparator, a divide–by–4, 16, 64 or 100 counter and a programmable divide–by–N 4–bit binary counter (all positive–edge triggered) constructed with MOS P–channel and N–channel enhancement mode devices (complementary MOS) in a monolithic structure. The MC14568B has been designed for use in conjunction with a programmable divide–by–N counter for frequency synthesizers and phase– locked loop applications requiring low power dissipation and/or high noise immunity. This device can be used with both counters cascaded and the output of the second counter connected to the phase comparator (CTL high), or used independently of the programmable divide–by–N counter, for example cascaded with a MC14569B, MC14522B or MC14526B (CTL low).
