DESCRIPTION
The 74LV107 is a low-voltage Si-gate CMOS device that is pin and function compatible with 74HC/HCT107. The 74LV107 is a dual negative-edge triggered JK-type flip-flop 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 sl……
