Nexperia USA Inc. 74AUP1GU04GX,125

Overview

74AUP1GU04GX,125 from Nexperia is a single unbuffered CMOS inverter optimized for ultra-low-power operation across 0.8 V to 3.6 V supply rails, delivering ICC ≤ 0.9 μA (max) at −40 °C to +125 °C, propagation delay as low as 0.3 ns (VCC = 3.6 V, CL = 5 pF), and IOFF-enabled partial power-down mode - used in battery-powered sensor nodes and voltage-level translation in portable IoT endpoints.

For engineers reviewing the 74AUP1GU04GX,125 datasheet, 74AUP1GU04GX,125 pinout, 74AUP1GU04GX,125 application, or 74AUP1GU04GX,125 equivalent, key selection criteria include guaranteed operation down to 0.8 V, input overvoltage tolerance to 3.6 V, sub-1 ns propagation at 3.0 V, thermal-enhanced X2SON5 package (0.8 × 0.8 × 0.32 mm), and JEDEC-compliant ESD robustness (HBM > 5000 V).

Technical Context

This device implements a single-stage unbuffered inverter topology with no internal gain staging, enabling minimal propagation delay and reduced capacitive loading versus buffered variants. Its IOFF circuitry actively isolates inputs/outputs during power-down, preventing leakage paths when VCC = 0 V.

It supports five JEDEC voltage standards (JESD8-12 through JESD8C) and operates reliably across −40 °C to +125 °C with input thresholds defined as VIH ≥ 0.75×VCC and VIL ≤ 0.25×VCC - ensuring noise margins >25% of VCC across the full supply range.

FAQ

Can 74AUP1GU04GX,125 operate at 0.7 V supply?

No. The absolute minimum recommended VCC is 0.8 V per Table 6. Operation below 0.8 V risks undefined logic states, increased propagation delay variability, and potential failure to meet VIH/VIL thresholds - confirmed by static characterization data showing VIH min = 0.75×VCC, which falls below valid HIGH detection at 0.7 V.

Does the X2SON5 package support reflow soldering per IPC-J-STD-020?

Yes. SOT1226-3 (X2SON5) is qualified for standard lead-free reflow profiles with peak temperature ≤260 °C, per Nexperia's package reliability documentation. Its 0.32 mm height and thermal-enhanced construction enable uniform heating and reduced warpage risk compared to thinner XSON variants.

Is the IOFF function active when VCC = 0.3 V?

No. IOFF activates only when VCC is fully discharged (0 V). At VCC = 0.3 V, the internal circuitry remains partially biased, and IOFF is not guaranteed - Table 6 specifies IOFF functionality under "VCC = 0 V" condition, and limiting values confirm VCC min = −0.5 V, meaning operation near 0 V is outside recommended conditions.

What is the maximum capacitive load for guaranteed 1.8 ns tpd at 3.6 V?

5 pF. Table 8 shows tpd max = 1.8 ns at VCC = 3.0 V to 3.6 V and CL = 5 pF. At CL = 10 pF, tpd max increases to 2.7 ns; at CL = 30 pF, it reaches 5.7 ns. For timing-critical paths requiring ≤1.8 ns, load capacitance must be held to ≤5 pF including trace and probe contributions.
