Description

The CD54HC123F is a high-speed CMOS Logic Dual Retriggerable Monostable Multivibrator designed and manufactured by Texas Instruments. This integrated circuit is part of the advanced high-speed CMOS family and is fabricated with silicon gate CMOS technology.

It is designed to produce precise time delays and retriggerable one-shot events, making it suitable for a wide range of applications in digital systems. The device features two independent monostable multivibrators with separate reset and trigger inputs for each multivibrator. The CD54HC123F is capable of operating in either a stable or a monostable mode, with the latter being initiated by a transition on the trigger input.

The timing period for each multivibrator is controlled by an external resistor and capacitor, allowing users to customize the timing intervals as per their application requirements. The device also includes leading-edge triggering (A) and trailing-edge triggering (B) inputs, which can be used independently or connected together to allow the device to be triggered on any desired edge of the input pulse.

Key Features:

  • Wide Supply Voltage Range: 2V to 6V, compatible with a variety of logic families.
  • High Noise Immunity: Characteristic of CMOS devices, providing robust performance in noisy environments.
  • Low Power Consumption: Ideal for battery-powered and portable applications.
  • Retriggerable for Very Long Pulses: No limitations on pulse width due to retriggering.
  • Separate Resets: Allows for greater flexibility in timing adjustments.
  • Output Pulse Width Range: From very narrow to extremely wide pulses, adjustable via external RC network.
  • Lead-free and RoHS Compliant: Meets environmental standards for hazardous substance regulations.

The CD54HC123F is available in a ceramic flat package and is characterized for operation from -55°C to 125°C, making it reliable for use in a broad range of industrial and military applications. Whether you're designing timing circuits, pulse generation systems, or require a stable multivibrator for your digital designs, the CD54HC123F from Texas Instruments is a versatile and reliable choice.
