74LS221 Datasheet Dual Monostable Multivibrators

Manufacturer: onsemi

Overview: SN74LS221 Dual Monostable Multivibrators with Schmitt-Trigger Inputs Each multivibrator of the.

Key Features

  • a negative-transitiontriggered input and a positive-transition-triggered input either of which can be used as an inhibit input. Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse. Schmitt-trigger input circuitry for B input allows jitter-free triggering for inputs as slow as 1 volt / second, providing the circuit with excellent noise immunity. A high immunity to VCC noise is also provided by internal latching circuitry. Once triggered, the out.
