MC14569B
Programmable Divide-By-N
Dual 4-Bit Binary/BCD
Down Counter
The MC14569B is a programmable dividebyN dual 4bit binary
or BCD down counter constructed with MOS PChannel and
NChannel 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, phaselocked loops,
and other frequency division applications requiring low power
dissipation and/or high noise immunity.
Features
Speedup Circuitry for Zero Detection
Each 4Bit Counter Can Divide Independently in BCD or Binary Mode
Can be Cascaded With MC14526B for Frequency Synthesizer
Applications
All Outputs are Buffered
Schmitt Triggered Clock Conditioning
These Devices are PbFree and are RoHS Compliant
NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AECQ100

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highimpedance circuit. For proper operation, V

Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
