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. QUICK REFERENCE DATA GND = 0 V; Tamb = 25 C; tr = tf = 6 ns TYPICAL SYMBOL tPHL/ tPLH PARAMETER propagation delay nCP to nQ nCP to nQ nR to nQ, nQ fmax CI CPD Notes 1. CPD is used to determine the dynamic power dissipation (PD in W): PD = CPD x VCC2 x fi + (CL x VCC2 x fo) where: fi = input frequency in MHz fo = output frequency in MHz (CL x VCC2 x fo) = sum of outputs CL = output load capacitance in pF VCC = supply voltage in V 2. For HC the condition is VI = GND to VCC For HCT the condition is VI = GND to VCC - 1.5 V.
