Nexperia USA Inc. 74AUP1G34GX4Z

Overview

74AUP1G34GX4Z from Nexperia is a single low-power Schmitt-trigger buffer IC in X2SON4 package (SOT1269-2), operating from 0.8 V to 3.6 V supply, delivering 1.4 μA max ICC at 125 °C, 4-terminal pinout (VCC, GND, A, Y), and propagation delay as low as 1.0 ns at 3.6 V with 5 pF load - used for signal conditioning in ultra-low-power IoT sensor interfaces and battery-powered wearables.

For engineers reviewing the 74AUP1G34GX4Z datasheet, 74AUP1G34GX4Z pinout, 74AUP1G34GX4Z application, or 74AUP1G34GX4Z equivalent, key selection criteria include its IOFF-enabled partial power-down capability, ±0.75 μA max IOFF leakage at VCC = 0 V, Schmitt-trigger input hysteresis for noisy rail-to-rail signals, and thermal-enhanced 0.6 × 0.6 × 0.32 mm X2SON4 footprint for space-constrained PCBs.

Technical Context

This device implements a non-inverting digital buffer with Schmitt-trigger inputs, enabling robust noise immunity on slow-rising or undershoot-prone signals across its full 0.8–3.6 V VCC range. Its IOFF circuitry actively disables output terminals when VCC = 0 V, preventing backflow current during system-level power sequencing.

It complies with JEDEC standards JESD8-12 through JESD8C for multi-voltage interoperability and meets HBM ESD rating >5000 V and CDM >1000 V. Propagation delay scales predictably with supply voltage and load capacitance - e.g., 1.0–4.2 ns over 3.0–3.6 V at CL = 5 pF - supporting timing-critical level-shifting in mixed-voltage domains.

FAQ

Does 74AUP1G34GX4Z support true bidirectional operation?

No. It is a unidirectional non-inverting buffer with fixed input (A) and output (Y) terminals. There is no internal direction control or bus-hold functionality. The device does not support data flow reversal or bus arbitration; it functions strictly as a one-way signal conditioner with Schmitt-trigger input and CMOS output stage.

Can 74AUP1G34GX4Z be used with 5 V tolerant inputs?

No. Inputs are overvoltage tolerant up to 3.6 V maximum - exceeding this risks permanent damage. While the device operates down to 0.8 V VCC, input voltage must remain within -0.5 V to +4.6 V absolute maximum ratings, but functional operation is only guaranteed between 0 V and VCC (≤3.6 V). External clamping is required for 5 V signal sources.

What is the significance of the 'Z' suffix in 74AUP1G34GX4Z?

The 'Z' suffix denotes tape-and-reel packaging per standard Nexperia ordering convention - specifically, 10,000 units per reel in X2SON4 carrier tape (EIA-481 compliant). It does not indicate a functional or parametric variant; electrical and thermal specifications match the base 74AUP1G34GX4 part number exactly.

How does the IOFF feature behave during brown-out conditions?

IOFF activates when VCC falls below ~0.2 V, disabling the output driver and limiting leakage to ±0.75 μA. During gradual brown-out (e.g., VCC dropping from 3.3 V to 0.5 V), the device remains fully functional until VCC crosses the IOFF threshold - then transitions cleanly to high-impedance state without oscillation or shoot-through, protecting downstream circuits.
