The SN74LVC112AD, manufactured by Texas Instruments, is a high-performance, dual JK flip-flop integrated circuit with negative-edge-triggered inputs. Designed for use in a wide array of applications, this component is part of the LVC family, which is known for its low-voltage operation and compatibility with mixed-voltage systems.

Each flip-flop in the SN74LVC112AD has independent J, K, set, reset, and clock inputs, with Q and Q^¯ outputs. This level of independence allows for a broad range of toggling functionalities, making it a versatile choice for designers. The negative-edge-triggered design ensures that the flip-flop changes state on the falling edge of the clock signal, providing precise control over data transfer and synchronization.

Operating within a voltage range of 2.7V to 3.6V, the SN74LVC112AD is optimized for low-voltage applications and is particularly well-suited for interfacing with 3.3V systems. Additionally, it provides 5V-tolerant inputs, which allows for direct interfacing with 5V TTL logic without the need for additional level shifting. This makes it an excellent choice for mixed-voltage environments where both 3.3V and 5V systems are present.

The SN74LVC112AD comes in a standard SOIC-16 package, which is conducive to automated assembly processes and is also available in TSSOP and TVSOP packages. Its robust latch-up performance exceeds 250mA per JESD 17, and it also features ESD protection exceeding JESD 22, ensuring reliability and longevity in demanding applications.

Ideal for applications requiring high-speed data capture, frequency division, or sequential logic, the SN74LVC112AD is a staple in digital electronics. Its low power consumption and high noise immunity are characteristics of the LVC family, making it a smart choice for battery-operated devices, portable electronics, and other power-sensitive applications.
