Overview
The 74HC73D-Q100J, produced by Nexperia USA Inc., is a dual negative edge triggered JK flip-flop integrated circuit. This component features individual J, K, clock (nCP), and reset (nR) 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. The device is also equipped with clamp diodes on the inputs, allowing the use of current limiting resistors to interface inputs to voltages in excess of VCC. This IC is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for automotive applications.
