NTE74221 - Dual Monostable Multivibrator

General Description

The NTE74221 is a monolithic dual multivibrator in a 16

Lead plastic DIP type package with performance characteristics virtually identical to those of the NTE74121.

Key Features

  • a negative.
  • transition.
  • triggered input and a positive.
  • transition.
  • triggered input either of which can be used as an inhibit input. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt.
  • trigger input circuitry (TTL hysteresis) for B input allows jitter.
  • free triggering from inputs with transition rates as slow as 1 volt/second, providing the circuit with excellent noise immu.

NTE74221 Integrated Circuit TTL − Dual Monostable Multivibrator Description: The NTE74221 is a monolithic dual multivibrator in a 16−Lead plastic DIP type package with performance characteristics virtually identical to those of the NTE74121. Each multivibrator features a negative−transition−triggered input and a positive−transition−triggered input either of which can be used as an inhibit input. Pulse triggering occurs at a particular voltage level and is not directly related to the transition time of the input pulse. Schmitt−trigger input circuitry (TTL hysteresis) for B input allows jitter−free triggering from inputs with transition rates as slow as 1 volt/second, providing the circuit with excellent noise immunity of typically 1.2 volts. A high immunity to VCC noise of typically 1.
