The SN74123N is a dual retriggerable monostable Multi-vibrator features output pulse-duration control by three methods. The basic pulse time is programmed by selection of external resistance and capacitance values. The LS123 is provided enough Schmitt hysteresis to ensure jitter-free triggering from the B-input with transition rates as slow as 0.1mV per nanosecond.
DC triggered from active-high or active-low gated logic inputs
Retriggerable for very long output pulses, up to 100% duty cycle
