Overview
The 74LVC74AD/C118 is a dual D-type flip-flop integrated circuit produced by NXP USA Inc. This component is part of the LVC (Low-Voltage CMOS) family and is designed for use in a wide range of digital logic applications. It features individual data (D) inputs, clock (CP) inputs, set (SD) and reset (RD) inputs, and complementary Q and Q outputs. The flip-flop is positive-edge triggered, meaning the data input is transferred to the output on the LOW-to-HIGH transition of the clock pulse.
