IN74HC221A - Dual Monostable Binary Up/Down Counter

TECHNICAL DATA IN74HC221A Dual Monostable Multivibrator The IN74HC221A 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 RESET input (positiveedge) because of the Schmitt-trigger input; after triggerin
