SEMICONDUCTOR TECHNICAL DATA
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

This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields. However, pre-
cautions must be taken to avoid applications of
any voltage higher than maximum rated volt-
ages to this high–impedance circuit. For proper
operation, Vin and Vout should be constrained
to the range VSS
(Vin or Vout)
VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD). Unused outputs must be left open.

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.
