System Logic Semiconductor SL74HC221

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. 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 maintains the MONOSTABLE state for the time period determined by the external resistor RX and capacitor CX.
