Overview
The MC74HC174ADR2G is a high-performance silicon-gate CMOS hex D flip-flop with a common clock and reset, manufactured by onsemi. This device is identical in pinout to the LS174 and is designed to be compatible with standard CMOS outputs and LSTTL outputs when used with pullup resistors. It consists of six D flip-flops, each loaded with a low-to-high transition of the clock input, and features an asynchronous active-low reset.
