Overview
The 74HC107DB,118 is a dual negative-edge triggered JK flip-flop integrated circuit produced by Nexperia. This component features individual J and K inputs, a clock (CP) input, and a reset (R) input, along with complementary Q and Q outputs. The reset is an asynchronous active LOW input, operating independently of the clock input. This IC is part of the 74HC series, known for its CMOS low power dissipation and high noise immunity.
