The SN74HC112D from Texas Instruments is a high-performance, dual J-K flip-flop integrated circuit that features negative-edge-triggered flip-flops with individual J, K, clock (CLK), and asynchronous set (SET) and reset (RESET) inputs for each flip-flop. This device is part of the HC family and is designed to operate from 2V to 6V, making it suitable for a wide range of applications including battery-powered devices, portable electronics, and logic interface circuits.
The SN74HC112D is designed for high-speed operation, even at the extremes of the power supply range. The balanced propagation delay and transition times significantly contribute to its performance characteristics. This flip-flop is capable of toggling at frequencies up to 32MHz at 5V, which is advantageous for various high-speed synchronous operations.
Each flip-flop has independent J, K, set, reset, and clock inputs and Q and Q̅ outputs. The set and reset are asynchronous active-LOW inputs and operate independently of the clock input. The J-K design allows the flip-flop to operate as a toggle flip-flop by connecting J and K together. When the clock goes HIGH, the inputs are locked in, and the outputs will change state on the next negative-going transition of the clock.
This device is fabricated with high-performance silicon-gate CMOS technology, which provides the inherent benefits of CMOS—low power consumption and high noise immunity. The SN74HC112D is available in a standard SOIC-16 package, which is RoHS compliant and compatible with both wave and reflow soldering techniques, making it easy to integrate into various types of electronic assemblies.
With its robust design and versatility, the SN74HC112D is ideal for a broad spectrum of digital applications, ranging from binary counters to shift registers and control circuits. Its capability to handle both analog and digital functions makes it an essential component for modern digital systems.
