Overview
The 74HCT74PW-Q100,118 is a dual positive edge-triggered D-type flip-flop produced by Nexperia USA Inc. This component is part of the 74HCT series, which is known for its compatibility with TTL (Transistor-Transistor Logic) levels. The device features individual data (nD), clock (nCP), set (nSD), and reset (nRD) inputs, along with complementary nQ and nQ outputs. It is designed to be highly tolerant to slower clock rise and fall times due to the Schmitt-trigger action in the clock input. This flip-flop is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive applications.
