74LS221 Dual Non-Retriggerable One-Shot with Clear and Complementary Outputs

General Description The DM74LS221 is a dual monostable multivibrator with Schmitt-trigger input. Each device has three inputs permitting the choice of either leading-edge or trailing-edge triggering. Pin (A) is an active-LOW trigger transition input and pin (B) is an active-HIGH transition Sc
