Overview
The MC74HC165ADTR2G is an 8-bit serial or parallel-input/serial-output shift register produced by onsemi. This device is part of the HC165A series, which is known for its high-performance silicon-gate CMOS technology. It is designed to be compatible with standard CMOS outputs and, with pull-up resistors, can also interface with LSTTL outputs. The MC74HCT165A variant can serve as a level converter for interfacing TTL or NMOS outputs to high-speed CMOS inputs.
