1. General description

The 74HC73-Q100 is a dual negative edge triggered JK flip-flop with individual J, K, clock (nCP)

and reset (nR) inputs and complementary nQ and nQ outputs. The J and K inputs must be

stable one set-up time prior to the HIGH-to-LOW clock transition for predictable operation. (nR)

is asynchronous, when LOW it overrides the clock and data inputs, forcing the nQ output LOW

and the nQ output HIGH. Schmitt-trigger action in the clock input makes the circuit highly tolerant

to slower clock rise and fall times. Inputs include clamp diodes. This enables the use of current

limiting resistors to interface inputs to voltages in excess of VCC.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100

(Grade 1) and is suitable for use in automotive applications.
