Datasheet

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 V
CC
.
