Description

The 74HC423 is a high-speed CMOS IC that features two independent retriggerable monostable multivibrators. Each monostable multivibrator (also known as a one-shot) is used to generate a single pulse of adjustable width in response to an input trigger. The pulse width is determined by an external RC network. The retriggerable feature allows the pulse width to be extended if additional trigger pulses are received during the pulse duration.

Features

  • Dual Monostable Multivibrators: Contains two separate monostable circuits, each with its own timing and triggering functions.
  • Retriggerable Operation: Allows pulse width to be extended if a new trigger is received during the active pulse period.
  • Adjustable Pulse Width: Pulse width is set by an external resistor-capacitor (RC) network.
  • High-Speed Operation: Designed for fast response with low propagation delays.
  • Wide Operating Voltage Range: Operates from 3V to 15V, providing flexibility for different power supplies.
  • Low Power Consumption: Uses CMOS technology for efficient power use.
  • TTL-Compatible Inputs and Outputs: Compatible with standard TTL logic levels.

Specifications

  • Logic Family: HC (High-Speed CMOS)
  • Number of Monostable Multivibrators: 2
  • Operating Voltage Range: 3V to 15V
  • Pulse Width Range: Determined by external RC components, typically from microseconds to milliseconds
  • Propagation Delay: Typically 14 ns (at Vcc = 5V)
  • Supply Current: 1 µA (maximum at 5V)
  • Output Drive Capability: 10 LSTTL loads
  • Operating Temperature Range: -40°C to 125°C
  • Package Type: DIP-16
