Descriptions:

The HD74HC4020P is a 14-bit binary counter with an asynchronous reset. It operates in the HC logic family, providing high-speed performance with low power consumption. The counter advances on the falling edge of the clock signal, and the reset input clears all outputs when activated.

Features:

  • 14-bit ripple carry binary counter
  • Asynchronous master reset
  • Wide operating voltage range (2V to 6V)
  • Low power consumption
  • High noise immunity
  • Compatible with TTL inputs
  • Standard DIP-16 package

This IC is commonly used in frequency division, timing circuits, and digital counting applications.
