Overview
The MC74HC74ADTR2 is a dual D flip-flop integrated circuit produced by onsemi. It is part of the HC74 series, known for its high-performance silicon-gate CMOS technology. This device is identical in pinout to the LS74 and is designed to be compatible with standard CMOS outputs, as well as LSTTL outputs when used with pullup resistors. The MC74HC74ADTR2 consists of two D flip-flops, each with individual Set, Reset, and Clock inputs, allowing for asynchronous Set and Reset operations. Information at the D-input is transferred to the corresponding Q output on the next positive-going edge of the clock input, with both Q and Q' outputs available from each flip-flop.
