IC 74121 MONOSTABLE MULTIVIBRATOR

MONOSTABLE MULTIVIBRATOR WITH SCHMITT TRIGGER INPUT

This multivibrator features dual negative-transition-triggered inputs and a single positive-transition-triggered input, which can be used as an inhibit input. Schmitt trigger input circuitry (TTL hysteresis) for the B input allows jitter-free triggering from inputs with transition rates as slow as 1V/sec, providing the circuit with excellent noise immunity of typically 1.2V.


Features:

• Programmable output pulse width
• Internal compensation for virtual temperature independence
• Jitter-free operation up to 90% duty cycle
• Inhibit capability
• DIP-14 configuration (14 pins)
