DM74121 Datasheet Monostable Multivibrator

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: 54121 DM54121 DM74121 One-Shot with Clear and plementary Outputs June 1989 54121 DM54121 DM74121 One-Shot with Clear and plementary Outputs.

General Description

The DM54 74121 is a monostable multivibrator featuring both positive and negative edge triggering with plementary outputs An internal 2kX timing resistor is provided for design convenience minimizing ponent count and layout problems This device can be used with a single external capacitor Inputs (A) are active-low trigger transition inputs and input (B) is an active-high transition Schmitt-trigger input that allows jitter-free triggering from inputs with transition rates as slow as 1 volt second A high immunity to VCC noise of typically 1 5V is also provided by internal circuitry at the input stage To obtain optimum and trouble free operation please read operating rules and NSC one-shot application notes carefully and observe remendations

Key Features

  • Y Triggered from active-high transition or active-low transition.
