Description

The SN74HC393 device from Texas Instruments is a high-performance, dual 4-bit binary counter integrated circuit. This chip is part of the HC family, which means it is fabricated with silicon gate CMOS technology. It offers the inherent advantages of CMOS circuitry, such as low power consumption, high noise immunity, and robust performance in a wide range of operating conditions.

Key Features

  • Wide Operating Voltage Range: The SN74HC393 operates at a voltage range of 2 V to 6 V, making it versatile for various applications.
  • High-Current Outputs: It can drive up to 15 LSTTL loads, which is significant for interfacing with various logic families.
  • Low Power Consumption: The typical power consumption is low, with only 80 µA of maximum ICC at 4 MHz, which is ideal for battery-operated devices.
  • Two Independent Counters: The chip contains two independent 4-bit binary counters, each having a clear and a clock input.
  • Direct Clear Function: Each counter has a direct clear input which, when made high, resets the counter to its zero state.
  • Simple Interface: The counters advance on the falling edge of the clock signal, simplifying the interface with microcontrollers or other digital logic.

Applications

The SN74HC393 is versatile and can be used in a variety of applications, including:

  • Frequency Dividers
  • Timers
  • Counters
  • Time-Delay Circuits
  • Alarm Systems

Package Options and Quality

Texas Instruments offers the SN74HC393 in multiple package options, including PDIP, SOIC, and VSSOP. This ensures that the chip can be integrated into a wide range of product designs. Additionally, the SN74HC393 is characterized for operation from -40°C to 85°C, guaranteeing reliable performance in diverse environments.

With its combination of features, the SN74HC393 is an excellent choice for designers looking for a reliable and efficient binary counter for their digital systems.
