Description

The 74HC393 contains two identical, independent 4-bit binary counters. Each counter operates as a modulo-16 counter, providing four outputs that represent a binary count from 0 to 15. The counters are triggered by the rising edge of the clock signal, and the outputs progress in a ripple fashion. Both counters can be asynchronously reset to zero using the reset input.

Features

  • Dual Independent Counters: Two separate 4-bit binary counters in one package.
  • Ripple (Asynchronous) Operation: Each flip-flop within the counter is triggered by the previous one, resulting in a ripple effect.
  • Asynchronous Reset: Each counter can be reset independently, which forces the outputs to zero.
  • High-Speed Operation: Fast switching times allow for high-frequency counting.
  • Low Power Consumption: CMOS technology ensures minimal power usage.
  • Wide Operating Voltage Range: Operates from 2V to 6V.
  • Noise Immunity: Provides high noise immunity for reliable operation in digital environments.
