MC14568B DIP IC

‘
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).
? Supply Voltage Range = 3.0 to 18 V
? Capable of Driving Two Low?Power TTL Loads, One Low?Power
Schottky TTL Load or Two HTL Loads Over the Rated Temperature
Range.
? Chip Complexity: 549 FETs or 137 Equivalent Gates
