NXP 74AUP1G74DC,125: A Low-Power Single D-Type Flip-Flop with Set and Reset

The NXP 74AUP1G74DC,125 is a high-performance, single positive-edge-triggered D-type flip-flop featuring asynchronous set (SD) and reset (RD) inputs, all integrated into an ultra-small and leadless DFN1010D-6 package. Designed with NXP's advanced 74AUP technology, this device is engineered for use in very low-power and low-voltage applications, making it a cornerstone component for modern portable and battery-operated electronics.

A key attribute of this flip-flop is its exceptionally low power consumption, a critical requirement for extending battery life in devices such as smartphones, wearables, and IoT sensors. The IC operates across a broad voltage range from 0.8 V to 3.6 V, providing designers with the flexibility to interface with both legacy and cutting-edge low-voltage processors and system-on-chips (SoCs) without the need for level shifters. The inclusion of both set and reset pins allows for immediate control over the output state (Q), enabling forced initialization, which is vital for system boot-up sequences and error recovery scenarios.

The device is fully specified for partial power-down applications, featuring Ioff circuitry that disables the output when the power is switched off. This prevents any damaging backflow current through the IC when it is in a powered-down state, thereby enhancing system reliability. Furthermore, its high noise immunity ensures stable operation even in electrically noisy environments, a common challenge in densely packed PCBs.

ICGOOODFIND: The 74AUP1G74DC,125 stands out as an optimal solution for designers seeking to minimize power and space without compromising on functionality or noise performance. Its robust feature set tailored for low-voltage operation makes it an indispensable logic element in advanced digital designs.
