General Description
The NTE74LS221 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.
