The 74HC112D is a Surface Mount Device (SMD) Integrated Circuit (IC) that is commonly used in digital logic circuits. The IC is a dual negative-edge triggered JK flip-flop, which means it has two flip-flops in one package that can be triggered by a negative transition of the clock input signal.

Features:

1. Dual J-K flip-flops: The 74HC112D SMD IC contains two J-K flip-flops, which can store a single bit of digital data each.
2. High-speed operation: The 74HC112D SMD IC operates at high speeds, making it suitable for use in applications that require fast response times.
3. Low power consumption: The 74HC112D SMD IC has a low power consumption, making it energy efficient and ideal for battery-powered devices.
