74LS78 DIP Dual Negative Edge Triggered J-K Flip-Flop with Preset, Common Clock & Common Clear IC (14-Pin TTL Logic IC)

The 74LS78 DIP Dual Negative Edge Triggered J-K Flip-Flop IC is a TTL sequential logic integrated circuit that contains two independent J-K flip-flops with asynchronous preset inputs, a common clock, and a common clear input in a 14-pin Dual Inline Package (DIP). Built using Low Power Schottky (LS) TTL technology, it delivers high-speed operation, low power consumption, and reliable sequential logic performance.

The flip-flops are negative edge triggered, meaning state changes occur on the falling edge of the clock signal. With shared clock and clear inputs, the IC is ideal for synchronized digital systems, counters, frequency dividers, registers, state machines, and timing circuits.
