MC74HC175AD

Flip Flops Overview

The MC74HC175AD is a quad D-type flip-flop manufactured by onsemi, belonging to the 74HC logic family. It features four independent D-type flip-flops with positive-edge triggering and an asynchronous master reset input. The device operates within a supply voltage range of 2V to 6V and supports clock frequencies up to 35 MHz. Maximum propagation delay is specified at 22ns under conditions of 6V supply and 50pF load. Output drive capability provides 5.2mA for both high and low states, with a static current consumption of 4µA. It is housed in a 16-SOIC package (0.154" width) and functions across a temperature range of -55°C to 125°C.
