NXP 74LVC2G74DP: A Low-Power Dual D-Type Flip-Flop with 5V Tolerant Inputs and Reset

The NXP 74LVC2G74DP is a dual positive-edge triggered D-type flip-flop featuring individual data inputs, clock inputs, set and reset capabilities, and complementary outputs. Fabricated with NXP's advanced low-voltage CMOS technology, this device is engineered for high-speed operation while maintaining very low power dissipation, making it an ideal choice for portable and battery-sensitive applications.

A key feature of the 74LVC2G74DP is its 5V tolerant input capability. This allows the inputs to safely accept signals up to 5.5V, even when the device is operating at a lower supply voltage (as low as 1.65V). This characteristic is crucial for interfacing between different voltage domains in mixed-voltage systems, eliminating the need for additional level-shifting components and simplifying board design.

Each flip-flop features an asynchronous active-LOW reset (RD) input. When driven LOW, it immediately forces the output (Q) to a LOW state, independent of the clock signal. This provides designers with a powerful tool for initializing the system state or recovering from errors. The device operates on a wide supply voltage range from 1.65V to 5.5V, offering exceptional flexibility for use in everything from 1.8V to 3.3V and 5V environments.

Housed in a space-saving 8-pin TSSOP package, the 74LVC2G74DP is optimized for applications where board space is at a premium. Its combination of low power consumption, high noise immunity, and robust performance makes it exceptionally suitable for a wide array of digital logic applications, including:

Portable and battery-operated electronics

Signal gating and registration

General-purpose logic circuit design

Temporary data storage and buffering

ICGOODFIND: The NXP 74LVC2G74DP stands out as a highly versatile and robust solution for modern digital design. Its 5V tolerant inputs and wide operating voltage range ensure seamless integration into complex mixed-voltage systems, while its low-power consumption and compact form factor make it an excellent choice for space- and power-constrained applications, from consumer electronics to industrial controls.
