NXP 74HC112 Dual J-K Flip-Flop with Set and Reset

The NXP 74HC112 is a high-speed Si-gate CMOS device and is pin compatible with low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. The 74HC112 is a dual negative-edge triggered J-K flip-flop featuring individual J, K, set (SD), and reset (RD) inputs; also, it provides complementary Q and Q outputs. This device can be used in a wide range of applications, from signal processing to system control where it is necessary to capture data in a synchronized manner.

The J-K flip-flop is versatile and is often used in counters, shift registers, and control circuits. The J and K inputs can handle pulse lengths as short as standard CMOS pulse durations. The flip-flop changes state on the falling edge of the clock pulse if the J and K inputs are different. If J and K are both high at the clock pulse, the output will toggle. A low logic level on the set or reset inputs will set or reset the outputs regardless of the logic levels of the other inputs.

Key features of the NXP 74HC112 include:

• Edge-triggered dual J-K flip-flop functionality
• Standard pinout for easy integration
• Multiple input options for flexible design implementations
• Complementary outputs for enhanced design flexibility
• Set-Reset capability independent of the clock
• Capability to handle fast pulse inputs
• High noise immunity and low power consumption
• Operating voltage range from 2.0V to 6.0V
• Latch-up performance exceeds 100mA per JESD 78 Class II Level B
• ESD protection: HBM JESD22-A114E exceeds 2000V, MM JESD22-A115-A exceeds 200V

The 74HC112 is offered in a variety of packages including DIP, SO, TSSOP, VSSOP, and DHVQFN, making it suitable for a broad array of PCB layouts and space-conscious applications. Its robust design ensures reliable performance in demanding environments, making it an excellent choice for designers looking for a dependable flip-flop solution. Whether you're working on a new electronic design or updating an existing system, the NXP 74HC112 provides the performance and flexibility needed to meet your design requirements.
