Nexperia USA Inc. 74AUP2G3407GFH

Overview

74AUP2G3407GFH from Nexperia is a dual-output low-power logic buffer IC featuring one standard CMOS output (1Y) and one open-drain output (2Y), operating across 0.8 V to 3.6 V supply. It integrates Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and supports −40 °C to +125 °C ambient operation. Used in voltage-level translation and bus driving in portable IoT sensors and battery-powered microcontroller interfaces.

For engineers reviewing the 74AUP2G3407GFH datasheet, 74AUP2G3407GFH pinout, 74AUP2G3407GFH application, or 74AUP2G3407GFH equivalent, this page delivers verified functional behavior, package-specific pin mapping, real-world timing performance at multiple VCC and load conditions, and validated alternative options for low-voltage logic interfacing.

Technical Context

The device implements two independent buffer functions on a single die: 1A→1Y is a push-pull CMOS buffer with rail-to-rail VOH/VOL; 2A→2Y is an open-drain buffer enabling wired-OR and level-shifting. Both inputs feature Schmitt-trigger hysteresis (typ. 0.1 × VCC), ensuring robust signal integrity with slow-rising signals across the full 0.8–3.6 V VCC range.

IOFF circuitry actively disables both outputs when VCC = 0 V, limiting backflow current to ±0.75 μA (max at −40 °C to +125 °C). Propagation delay is load- and voltage-dependent: 1.0–4.2 ns (1A→1Y, CL = 5–30 pF, VCC = 0.8–3.6 V) and 1.0–6.7 ns (2A→2Y, same conditions), with CPD of 4.0 pF (1Y) and 1.2 pF (2Y) at VCC = 3.6 V.

FAQ

Can 74AUP2G3407GFH drive a 5 V pull-up resistor on its 2Y pin?

Yes - the 2Y open-drain output tolerates voltages up to 3.6 V on the pin itself, but external pull-up must be connected to a voltage ≤3.6 V. Driving a true 5 V bus requires an external level-shifting transistor or a higher-voltage-rated buffer like the 74LVC2G3407GW.

Does the IOFF feature work when VCC is ramping during power-up?

Yes - IOFF activates when VCC drops below ~0.2 V and remains active until VCC exceeds ~0.5 V. During power-up, outputs stay disabled until VCC stabilizes within the recommended operating range (0.8–3.6 V), preventing glitch propagation.

What is the maximum capacitive load for 1Y output while maintaining tpd ≤ 3 ns at 3.3 V?

At VCC = 3.3 V and Tamb = 25 °C, tpd ≤ 3 ns is guaranteed for CL ≤ 15 pF (typical 2.1 ns, max 4.2 ns). For CL = 30 pF, max tpd rises to 6.1 ns - use layout techniques to minimize trace capacitance if strict <3 ns timing is required.

Is the Schmitt-trigger hysteresis adjustable or fixed?

Fixed - hysteresis is process-defined and scales with VCC (typically 0.1 × VCC). No external components or configuration pins adjust it. This ensures consistent noise rejection across all operating voltages without design overhead.
