HCT123M** is a **dual retriggerable monostable multivibrator** manufactured by **Texas Instruments (TI)**.

The HCT123M is a dual retriggerable monostable multivibrator manufactured by Texas Instruments (TI).

Key Specifications:

  • Logic Family: HCT (High-Speed CMOS, TTL-Compatible)
  • Supply Voltage Range: 4.5V to 5.5V
  • Propagation Delay: Typically 45 ns
  • Output Current: ±4 mA (sink/source)
  • Operating Temperature Range: -40°C to +85°C
  • Package: SOIC (Small Outline Integrated Circuit)

Descriptions:

  • Contains two independent retriggerable monostable multivibrators.
  • Features Schmitt-trigger inputs for noise immunity.
  • Output pulse width is adjustable via external timing components (resistor and capacitor).
  • Compatible with TTL and CMOS logic levels.

Features:

  • Retriggerable Operation: Allows extension of output pulse by retriggering before the pulse ends.
  • Direct Reset Input: Provides immediate termination of the output pulse.
  • Wide Range of Pulse Widths: Adjustable from nanoseconds to seconds using external RC components.
  • Low Power Consumption: Typical ICC of 40 µA (static).

This device is commonly used in timing circuits, pulse generation, and delay applications.
