Description

The TC74VHC123AF is a high-speed CMOS dual retriggerable monostable multivibrator. It is part of Toshiba's VHC (Very High-Speed CMOS) logic family, combining the speed of bipolar logic with the low power consumption of CMOS technology. This device consists of two independent monostable circuits, each triggered by either a rising or falling edge input signal. The output pulse width is determined by an external resistor (Rext) and capacitor (Cext). The retriggerable capability allows the output pulse to be extended if a trigger signal arrives before the end of the initial pulse.

Applications

  • Timers and pulse generators
  • Pulse delay circuits
  • Missing pulse detectors
  • Frequency discriminators
  • Time delay applications

Features

  • High-speed operation
  • Low power dissipation
  • Retriggerable capability
  • Wide operating voltage range: 2V to 5.5V
  • Schmitt-trigger inputs for slow or noisy input signals
  • Output pulse width control via external R and C
  • Pin compatible with HC123 and LS123

Benefits

  • Allows for precise timing and pulse generation.
  • Reduces power consumption, making it suitable for battery-powered devices.
  • Extends the output pulse width upon receiving a new trigger signal.
  • Provides flexibility in power supply options.
  • Ensures reliable triggering with slow or noisy input signals.
  • Allows for easy adjustment of the output pulse width.
  • Simple replacement for older logic devices.

Additional Details

The TC74VHC123AF is available in a small outline integrated circuit (SOIC) package. The external resistor and capacitor values determine the output pulse width. Consult the datasheet for appropriate component selection. It is commonly used where precise timing and pulse generation are needed.
