74LS12 - Dual Retriggerable One-Shot

General Description

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.

Each device has three inputs permitting the choice of either leading edge or trailing edge triggering. Pin (A) is an active-LOW transition trigger input and pin (B) is an activeHIGH transition trigger input. The clear (CLR) input terminates the output pulse at a predetermined time independent of the timing components.
