Overview
The 74HC73DB,112 is a dual negative edge triggered JK flip-flop integrated circuit produced by Nexperia USA Inc. This component features individual J, K, clock (nCP), and reset (nR) inputs along with complementary nQ and nQ outputs. The JK flip-flop is designed to be highly tolerant to slower clock rise and fall times due to the Schmitt-trigger action in the clock input. The asynchronous reset input (nR) overrides the clock and data inputs, forcing the nQ output LOW and the nQ output HIGH when it is LOW. The inputs include clamp diodes, enabling the use of current limiting resistors to interface inputs to voltages in excess of VCC.
