They are specified in compliance with JEDEC standard no. 7A. 74HC/HCT107 The 74HC/HCT107 are dual negative-edge triggered JK-type flip-flops featuring individual J, K, clock (nCP) and reset (nR) inputs; also complementary Q and Q outputs. The J and K inputs must be stable one set-up time prior to the HIGH-to-LOW clock transition for predictable operation. The reset (nR) is an asynchronous active LOW input. When LOW, it overrides the clock and data inputs, forcing the Q output LOW and the Q output HIGH. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
