74LS12 Datasheet (Fairchild Semiconductor) - Dual Retriggerable One-Shot

74LS12, Dual Retriggerable One-Shot

The DM74LS123 is a dual retriggerable monostable multivibrator capable of generating output pulses from a few nano-seconds to extremely long duration up to 100% duty cycle.

Each device has three inputs permitting the choice of either leading edge or trailing edge triggering.

Pin (A) is an active-LOW
