Overview
The 74AHCT74PW,112 is a dual positive-edge triggered, D-type flip-flop with set and reset inputs, manufactured by Nexperia USA Inc. This high-speed Si-gate CMOS device is pin compatible with Low-Power Schottky TTL (LSTTL) and is specified in compliance with JEDEC standard No. 7-A. It features individual data inputs (D), clock inputs (CP), set inputs (SD), and reset inputs (RD), along with complementary outputs (Q and Q).
The device is designed to operate over a wide voltage range of 2.0 to 5.5 volts and is suitable for various applications requiring high-speed logic operations. The asynchronous active LOW set and reset inputs operate independently of the clock input, making it versatile for different circuit designs.
