Nexperia USA Inc. 74AUP1G175GW,125

Overview

74AUP1G175GW,125 from Nexperia is a single positive-edge-triggered D-type flip-flop with asynchronous master reset (MR), operating from 0.8 V to 3.6 V supply. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and guaranteed operation from –40 °C to +125 °C. Its 6-pin TSSOP6 package supports low-power data latching in battery-powered sensor interfaces and portable logic subsystems.

For engineers reviewing the 74AUP1G175GW,125 datasheet, 74AUP1G175GW,125 pinout, 74AUP1G175GW,125 application, or 74AUP1G175GW,125 equivalent, key selection criteria include its ultra-low ICC (≤1.4 μA max), MR-to-Q propagation delay (≤12.0 ns at 3.0–3.6 V), Schmitt-trigger input hysteresis, IOFF-enabled backflow prevention, and TSSOP6 thermal performance up to +125 °C.

Technical Context

This device implements a synchronous D flip-flop with asynchronous active-low reset, where data at D is captured on the LOW-to-HIGH clock transition and appears at Q. The master reset overrides clock and data, forcing Q to LOW regardless of CP state.

Schmitt-trigger inputs provide hysteresis (VIH − VIL ≥ 0.3×VCC at 1.1–1.95 V), enabling robust operation with slow-rising signals. The IOFF circuit disables outputs when VCC = 0 V, limiting off-state leakage to ±0.75 μA and preventing damaging back-current in partial power-down systems.

FAQ

What is the minimum recommended VCC for reliable operation?

The 74AUP1G175GW,125 is fully specified from 0.8 V to 3.6 V. At VCC = 0.8 V, VIH is guaranteed ≥0.70×VCC (≥0.56 V), and tpd remains ≤21.1 ns (CL = 5 pF). Operation below 0.8 V is not characterized and may result in timing violations or undefined output states.

Does the MR input require external pull-up or debouncing?

No external pull-up is required: MR is active LOW and internally compatible with open-drain or CMOS logic drivers. Schmitt-trigger action provides inherent noise immunity, eliminating need for RC debouncing in most cases-though a 100 kΩ pull-up is recommended if left floating during power-up.

Can this device drive a 50 pF load reliably?

The datasheet characterizes tpd up to CL = 30 pF. At CL = 50 pF, propagation delay increases beyond guaranteed limits (e.g., >7 ns at VCC = 3.3 V), and fmax drops below 200 MHz. For 50 pF loads, verify timing margins in simulation or prototype; consider buffering if setup/hold violations occur.

How does IOFF behave when VCC ramps from 0 V to nominal?

IOFF activates when VCC falls below ~0.2 V and remains active until VCC exceeds ~0.4 V. During this transition, output impedance rises rapidly, limiting leakage to ±0.75 μA. Output remains in high-impedance state until VCC stabilizes above 0.8 V, ensuring safe power sequencing.
