74LS112 DIP Dual J-K Negative Edge Triggered Flip-Flop with Clear and Preset IC (16-Pin TTL Logic IC)

The 74LS112 DIP Dual J-K Negative Edge Triggered Flip-Flop with Clear and Preset IC is a high-speed TTL sequential logic integrated circuit containing two independent J-K flip-flops in a 16-pin Dual Inline Package (DIP). Built using Low Power Schottky (LS) TTL technology, it offers high-speed switching, low power consumption, and reliable sequential logic performance.

Each flip-flop is negative edge triggered, updating its output on the falling edge of the clock signal. The device also includes independent asynchronous active-low preset and clear inputs, allowing the outputs to be set or reset instantly regardless of the clock or logic inputs. The 74LS112 is widely used in binary counters, shift registers, state machines, frequency dividers, embedded systems, and industrial automation.
