Product Overview: 74HCT112 Dual JK Flip-Flop with Set and Reset

The 74HCT112 from NXP Semiconductors is a high-speed Si-gate CMOS device that is pin compatible with low power Schottky TTL (LSTTL). It is specifically designed to operate in the 4.5 V to 5.5 V range, making it suitable for a wide array of TTL-level applications. This integrated circuit is part of the 74HCT family, which is known for its robust performance and compatibility with TTL signals.

Key Features

• Dual JK flip-flop configuration: The device includes two JK flip-flops with individual set, reset, clock, and output capabilities, which allows for versatile use in a variety of logic circuits.
• Asynchronous set and reset: Both flip-flops come with direct clear and preset inputs for asynchronous operation, providing additional flexibility in control and initialization of the logic states.
• Edge-triggered clock: The flip-flops are negative-edge triggered, ensuring that the state change occurs on the falling edge of the clock signal for precise timing applications.
• Standard output capability: The outputs can drive up to 10 LSTTL loads, which is standard for the industry, ensuring compatibility with a wide range of digital circuits.
• High noise immunity: The 74HCT112 is characterized by its high noise immunity, which is typical of CMOS devices, making it reliable in electrically noisy environments.
• Low power consumption: The device has a balanced propagation delay and transition times, leading to reduced power consumption without sacrificing speed.
