Overview
NTE74LS221 Integrated Circuit TTL − Dual Monostable Multivibrator 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.
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...
