DM74LS123 - 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.

2000 DM74LS123 Dual Retriggerable One-Shot with Clear and Complementary Outputs 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. 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. The clear input also serves as a tri
