CD74HCT393E** is a dual 4-bit binary ripple counter manufactured by **HARRIS**.

The CD74HCT393E is a dual 4-bit binary ripple counter manufactured by HARRIS.

Specifications:

  • Logic Family: HCT (High-Speed CMOS, TTL compatible)
  • Supply Voltage Range: 4.5V to 5.5V
  • Operating Temperature Range: -55°C to +125°C
  • Number of Counters: 2 (Dual)
  • Counter Type: 4-bit binary ripple counter
  • Reset Function: Asynchronous master reset (active HIGH)
  • Output Type: Standard (TTL-compatible)
  • Propagation Delay: Typically 18 ns at 5V
  • Power Dissipation: Low power consumption (CMOS technology)
  • Package: 14-pin PDIP (Plastic Dual In-line Package)

Descriptions:

The CD74HCT393E consists of two independent 4-bit ripple counters, each with a clear input. The counters advance on the HIGH-to-LOW transition of the clock input. The asynchronous reset clears all flip-flops simultaneously.

Features:

  • High-Speed Operation: Compatible with TTL logic levels
  • Wide Operating Voltage: 4.5V to 5.5V
  • Low Power Consumption: CMOS technology
  • Asynchronous Reset: Allows immediate clearing of counters
  • Dual Counter Configuration: Two independent 4-bit counters in one package
  • Standard Output Drive: Suitable for driving TTL loads

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