Introduction

AI Translation

The 74LV123 is a low-voltage Si-gate CMOS device and is pin and function compatible with the 74HC123; 74HCT123. It is a dual retriggerable monostable multivibrator which uses three methods to control the output pulse width:

  1. The basic pulse time is programmed by the selection of an external resistor (R_EXT) and capacitor (C_EXT).
  2. Once triggered, the basic output pulse_width may be extended by retriggering the gated active LOW-going edge input (nA) or the active HIGH-going edge input (nB).
  3. Alternatively, an output delay can be terminated at any time by a LOW-going edge on input nRD, which also inhibits the triggering.

Schmitt-trigger action in the nA and nB inputs makes the circuit highly tolerant of slower input rise and fall times.

Features

AI Translation
  • Optimized for low-voltage applications: 1.0V to 5.5V
  • Accepts TTL input levels between V_CC = 2.7V and V_CC = 3.6V
  • Typical output ground bounce: <0.8V at V_CC = 3.3V and T_amb = 25℃
  • Typical HIGH-level output voltage (V_OH) undershoot: >2V at V_CC = 3.3V and T_amb = 25℃
  • DC triggered from active HIGH or active LOW inputs
  • Retriggerable for very long pulses up to 100% duty factor
  • Direct reset terminates output pulses
  • Schmitt-trigger action on all inputs except for the reset input
