NXP 74AUP1G175GW: A Comprehensive Technical Overview of the Single D-Type Flip-Flop with Reset

The NXP 74AUP1G175GW is a high-performance, single positive-edge-triggered D-type flip-flop featuring an asynchronous reset, packaged in a space-saving 6-pin SOT353 (SC-88A) package. As a member of NXP's advanced ultra-low-power (AUP) family, this IC is engineered to deliver an optimal balance of very low power consumption, high speed, and robust functionality, making it an ideal choice for a vast array of modern electronic applications, including portable devices, consumer electronics, and communication systems.

Core Functionality and Key Features

At its heart, the 74AUP1G175GW is a single-bit data storage element. Its primary function is to capture the logic level present at its D (Data) input pin at the moment of a low-to-high transition (positive edge) of the clock (CP) signal. This captured value is then immediately presented at the output (Q) and remains stored until the next positive clock edge. The inclusion of an asynchronous reset (MR) is a critical feature. When the MR pin is driven to a low logic level, it overrides all other inputs—including the clock—and forces the output Q to a low state immediately, regardless of the clock's condition. This provides designers with a powerful tool for initializing the circuit to a known state.

The defining characteristic of the AUP family is its exceptionally low power dissipation. The device operates with a 1.2 V to 3.6 V supply voltage, allowing for seamless integration into both low-voltage and legacy systems. It boasts an ultra-low static power consumption, typically measured in nanoamps (nA), which is paramount for battery-operated devices. Despite this minimal power usage, it does not sacrifice performance, offering high-speed operation with propagation delays typically just a few nanoseconds.

Application Hints and Design Considerations

The 74AUP1G175GW is incredibly versatile. Common applications include use as a data synchronizer, where it helps align a data signal with a clock domain to prevent metastability. It is also perfect for simple state storage in finite state machines (FSMs), as a temporary data latch in control circuits, or for registering signals in data paths. Its small form factor is particularly advantageous in space-constrained PCB designs.

For reliable operation, standard digital design practices should be followed. Unused inputs must never be left floating and should be tied to either VCC or GND, as appropriate. Bypass capacitors placed close to the VCC pin are recommended to suppress power supply noise. Designers must also be mindful of the asynchronous nature of the reset; while highly useful, its timing relative to the clock must be considered to avoid unintended glitches or metastable states on the output.

Conclusion and Advantages Summary

The 74AUP1G175GW stands out as a superior solution for modern digital design needs. Its combination of ultra-low power consumption, high-speed performance, a valuable reset function, and a miniature package encapsulates the requirements for next-generation portable and low-energy applications. It provides a reliable and efficient solution for simple data storage and control tasks where board space and power are at a premium.
