The IN74HC166A is identical in pinout to the LS/ALS166. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.This IN74HC166A is a parallel-in or serial-in, serial-out shift register wi...
The IN74HC165A is identical in pinout to the LS/ALS165. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. This IN74HC165A is an 8-bit shift register with complementary outputs from...
