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...
