1. General description
The 74HC107; 74HCT107 is a dual negative edge triggered JK flip-flop featuring individual J and
K inputs, clock (CP) and reset (R) inputs and complementary Q and Q outputs. The reset is an
asynchronous active LOW input and operates independently of the clock input. The J and K inputs
control the state changes of the flip-flops as described in the mode select function table. The J and
K inputs must be stable one set-up time prior to the HIGH-to-LOW clock transition for predictable
operation. Inputs include clamp diodes that enable the use of current limiting resistors to interface
inputs to voltages in excess of VCC.
