Presettable 4−Bit Down
Counters
The MC14526B binary counter is constructed with MOS P−channel
and N−channel enhancement mode devices in a monolithic structure.
This device is presettable, cascadable, synchronous down counter
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.
This complementary MOS counter can be used in frequency
synthesizers, phase−locked loops, and other frequency division
applications requiring low power dissipation and/or high noise
immunity.
Features
• 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
• Pb−Free Packages are Available*

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
high−impedance circuit. For proper operation, V

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