Nexperia USA Inc. 74AUP2G125DC,125

Overview

74AUP2G125DC from Nexperia is a dual 3-state buffer/line driver with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering ICC ≤ 0.9 μA (max), tpd ≤ 3.1 ns at 3.3 V/CL = 5 pF, and IOFF-enabled partial power-down protection. It serves in low-power I/O expansion and bus isolation for portable sensor interfaces and battery-powered microcontroller peripherals.

For engineers reviewing the 74AUP2G125DC datasheet, 74AUP2G125DC pinout, 74AUP2G125DC application, or 74AUP2G125DC equivalent, key selection criteria include ultra-low static current, wide-VCC compatibility, guaranteed 3-state behavior under power-down, and VSSOP8 package suitability for space-constrained PCB layouts.

Technical Context

This device implements two independent non-inverting buffers, each with active-low 3-state enable (nOE) controlling output impedance. Schmitt-trigger inputs provide hysteresis (typically 0.3 V at VCC = 3.3 V), enabling robust noise immunity against slow-rising signals in mixed-signal environments.

The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current up to ±20 mA per pin, satisfying JEDEC JESD78B Class II latch-up requirements (>100 mA). Input tolerance to 3.6 V allows interfacing with higher-voltage logic without level shifters.

FAQ

What is the maximum capacitive load the 74AUP2G125DC can drive while maintaining specified tpd?

The datasheet specifies propagation delay (tpd) performance up to CL = 30 pF across all VCC conditions. At VCC = 3.3 V and CL = 30 pF, tpd remains ≤ 8.3 ns - well within timing budgets for most microcontroller peripheral buses. Driving loads >30 pF may increase delay nonlinearly and require empirical validation.

Does the 74AUP2G125DC support hot insertion or live swapping in a powered system?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, preventing damaging backflow current even if inputs remain biased. This enables safe hot-plug operation in modular systems like field-replaceable sensor cards, provided VCC ramp rates comply with recommended slew limits (≤200 ns/V).

Can the Schmitt-trigger inputs be disabled or bypassed for standard CMOS thresholds?

No - Schmitt-trigger action is intrinsic to the input stage and cannot be disabled. The hysteresis (typically 0.3 V at 3.3 V) is fixed and provides guaranteed noise margin. For non-hysteresis behavior, an alternative part such as the 74LVC2G125 must be selected.

Is the VSSOP8 (SOT765-1) package of the 74AUP2G125DC compatible with standard reflow profiles for lead-free assembly?

Yes - the SOT765-1 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), supporting peak reflow temperatures up to 260 °C. Standard lead-free reflow profiles (e.g., SAC305) are fully compatible, with no special pre-bake required.
