MC14522B
Presettable 4-Bit Down Counters
-The MC14522B BCD counter and the MC14526B binary counter are
constructed with MOS P–channel and N–channel enhancement mode
devices in a monolithic structure.
These devices are presettable, cascadable, synchronous down counters
with a decoded “0” state output for divide–by–N applications. In single stage
applications the “0” output is applied to the Preset Enable input. The
Cascade Feedback input allows cascade divide–by–N operation with no
additional gates required. The Inhibit input allows disabling of the pulse
counting function. Inhibit may also be used as a negative edge clock.
These complementary MOS counters can be used in frequency synthesiz-
ers, phase–locked loops, and other frequency division applications requiring
low power dissipation and/or high noise immunity. Supply Voltage Range = 3.0 Vdc to 18 Vdc Logic Edge–Clocked Design — Incremented on Positive Transition of
Clock or Negative Transition of Inhibit Asynchronous Preset Enable Capable of Driving Two Low–power TTL Loads or One Low–power
Schottky TTL Load Over the Rated Temperature Range

†Temperature Derating:
Plastic “P and D/DW” Packages: – 7.0 mW/ C From 65 C To 125C
Ceramic “L” Packages: – 12 mW/ C From 100 C To 125C
FUNCTION TABLEX = Don’t Care
NOTES:
*Output “0” is low when reset goes high only it PE and CF are low.
**Output “0” is high when reset is low, only if CF is high and count is 0000.
