CD74HC107E

Overview

The CD74HC107E is a dual JK flip-flop integrated circuit manufactured by Harris Corporation. It contains two independent 1-bit JK flip-flops with negative edge triggering and asynchronous clear inputs. The device operates within a supply voltage range of 2V to 6V and features complementary outputs. It is housed in a 14-pin Dual In-Line Package (DIP) with a 0.300-inch width. The quiescent current is specified at 4 µA, and input capacitance is 10 pF. The operating temperature range extends from -55°C to 125°C.
