- Dual Monostable Multivibrator - Data
SL74HC221 Dual Monostable Multivibrator The SL74HC221 is identical in pinout to the LS, ALS221. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS, ALSTTL outputs. There are two trigger inputs, A INPUT (negative edge) and B INPUT (positive edge). These inputs are valid for rising, falling signals The device may also be triggered by using the CLR input (positiveedge) because of the Schmitt-trigger input; after triggering the output mai
