MC14526B: 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
