Overview
The 74HC73D,653 is a dual negative edge triggered JK flip-flop 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 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 Schmitt-trigger action in the clock input enhances the circuit's tolerance to slower clock rise and fall times. Additionally, the inputs include clamp diodes, allowing the use of current limiting resistors to interface inputs to voltages exceeding VCC.
