NXP 74LVC1G175GV: A Single D-Type Flip-Flop with Asynchronous Reset

The NXP 74LVC1G175GV is a high-performance, single positive-edge-triggered D-type flip-flop integrated circuit, featuring an asynchronous reset input. This device is a fundamental building block in digital logic design, providing a compact and efficient solution for data storage, synchronization, and transfer operations in a wide array of electronic applications.

Housed in an ultra-small SOT753 (SC-74A) package, this IC is specifically engineered for space-constrained portable devices. It operates within a broad voltage range from 1.65 V to 5.5 V, making it perfectly suited for mixed-voltage environments and ensuring compatibility with both modern low-voltage microcontrollers and legacy 5V systems. A key feature is its asynchronous reset (MR), which allows the output (Q) to be immediately forced to a low state regardless of the clock (CP) or data (D) inputs. This provides designers with immediate control to initialize the circuit to a known state, which is critical for system stability and error recovery.

The 74LVC1G175GV exhibits excellent performance characteristics. It supports high-speed operation with propagation delays typically in the range of a few nanoseconds. Furthermore, it boasts very low power consumption, a critical attribute for battery-powered devices. The inputs are 5V tolerant, allowing them to be driven by higher voltage signals without damage, which simplifies interfacing with other components.

Typical applications for this flip-flop are extensive. It is commonly used for:

Data synchronization and temporary storage in data paths.

Debouncing mechanical switch inputs.

Implementing simple state machines and frequency dividers.

Serving as a register in various control logic circuits.

ICGOOODFIND: The NXP 74LVC1G175GV stands out as an exceptionally versatile and robust single flip-flop solution. Its combination of a wide operating voltage, asynchronous reset functionality, and miniature package size makes it an ideal choice for designers seeking reliability and performance in modern, compact electronic designs.
