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 enhance-
ment 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 frequency division applications requiring low power dissipation and/or
high noise immunity.
•
Speed–up Circuitry for Zero Detection
•
Each 4–Bit Counter Can Divide Independently in BCD or Binary Mode
•
Can be Cascaded With MC14568B, MC14522B or MC14526B for
Frequency Synthesizer Applications
•
All Outputs are Buffered
•
Schmitt Triggered Clock Conditioning
