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 frequency division applications requiring low power
dissipation and/or high noise immunity.
Features
• Speed−up Circuitry for Zero Detection
• Each 4−Bit 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
• NLV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• This Device is Pb−Free and is RoHS Compliant

Stresses exceeding those listed in the Maximum Ratings table may damage the
device. If any of these limits are exceeded, device functionality should not be
assumed, damage may occur and reliability may be affected.
1. Temperature Derating: “D/DW” Package: –7.0 mW/_C From 65_C To 125_C
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
high−impedance circuit. For proper operation, V
in
and V
out
should be constrained
to the range V
SS
≤ (V

or V

) ≤ V
DD
.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either V
SS
or V
DD
). Unused outputs must be left open.
