Product Overview: 74HCT112N by NXP

The 74HCT112N is a high-speed Si-gate CMOS device designed and manufactured by NXP Semiconductors. This device is a part of the 74HCT series, which is compatible with Low Power Schottky TTL (LSTTL). It is specifically tailored for high-performance, high-speed applications in digital systems.

Key Features

• Dual JK flip-flop: The 74HCT112N contains two JK flip-flops with set and reset capabilities. This makes it an ideal choice for a variety of sequential logic applications.
• Asynchronous set and reset: Each flip-flop has independent set (SD) and reset (RD) inputs which are asynchronously active low. This feature allows for immediate setting or resetting of the flip-flop.
• Edge-triggered: The flip-flops are negative-edge triggered, meaning they respond to a falling edge of the clock pulse, providing precise control over data operations.
• Standard pinout: The device comes in a standard 16-pin DIP (Dual In-line Package), which is widely used and easily integrated into various circuit boards.
• High noise immunity: The 74HCT112N is characterized by its high noise immunity, which is typical of CMOS devices, ensuring stable performance in noisy environments.
• Low power consumption: Like other CMOS devices, it has a low power consumption, making it suitable for battery-operated and power-sensitive applications.
• TTL compatible: The inputs are TTL compatible, which allows for easy interfacing with TTL logic levels.
