The MC74LS112AD is a dual JK negative edge-triggered flip-flop with preset and clear manufactured by Freescale Semiconductor - NXP. This device is part of the LS family of low-power Schottky TTL logic, known for its relatively low power consumption and good speed. It contains two independent JK flip-flops, each with individual J, K, clock, preset, and clear inputs.

Additional Details

The MC74LS112AD consists of two independent JK flip-flops. Each flip-flop is triggered on the negative-going edge of the clock pulse. The J and K inputs determine the next state of the flip-flop. The preset and clear inputs are asynchronous and override the clock and data inputs. The device is typically available in a 16-pin SOIC package. Storage Temperature Range is -65°C to +150°C.
