Nexperia USA Inc. 74AXP1T32GXZ

Overview

74AXP1T32 from Nexperia is a dual-supply 2-input OR gate with independent input (VCCI) and output (VCCO) supply rails, enabling bidirectional voltage level translation between 0.7–2.75 V and 1.2–5.5 V domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, and operates across –40 °C to +85 °C. Used in mixed-voltage I/O bridging for FPGA-to-ASIC interfaces, sensor hub logic, and low-power microcontroller peripheral expansion.

For engineers reviewing the 74AXP1T32 datasheet, 74AXP1T32 pinout, 74AXP1T32 application, or 74AXP1T32 equivalent, this device supports precise voltage domain isolation, sub-1 ns transition times at 3.3 V, ultra-low static current (<0.5 µA at 85 °C), and JEDEC-compliant interface standards including JESD8-12A.01 and JESD8-C.

Technical Context

The 74AXP1T32 implements a single 2-input OR function with fully decoupled supply domains: inputs referenced to VCCI (0.7–2.75 V), output referenced to VCCO (1.2–5.5 V). Its Schmitt-trigger inputs tolerate slow edges (Δt/ΔV ≤ 200 ns/V) and provide high noise immunity across all operating voltages.

IOFF circuitry actively disables the output when either supply is near 0 V, blocking backflow current and enabling safe hot insertion in partial-power-down systems. Propagation delay ranges from 1.6 ns (VCCI = 2.5 V, VCCO = 5.0 V) to 148 ns (low-VCCI, wide temperature range), with load-dependent variation confirmed up to 120 pF.

FAQ

Can 74AXP1T32 operate with VCCI = 0.7 V and VCCO = 5.5 V simultaneously?

Yes. The device is fully specified for concurrent operation across its entire rated ranges: VCCI from 0.7 V to 2.75 V and VCCO from 1.2 V to 5.5 V. At these extremes, propagation delay increases to 148 ns (max), and VOH/VOL remain compliant per Table 7 - verified across –40 °C to +85 °C.

Does the IOFF feature activate automatically when power is removed?

Yes. IOFF engages whenever VCCI or VCCO falls below ~0.1 V, disabling the output stage and limiting back-current to ±0.5 µA maximum. This occurs without external control signals and is intrinsic to the silicon design - confirmed in Table 7's IOFF and ΔIOFF measurements.

What is the maximum capacitive load the 74AXP1T32 can drive reliably?

The device is characterized up to 120 pF load capacitance (Fig. 6–11), with propagation delay increasing linearly beyond 30 pF. For timing-critical paths, keep CL ≤ 30 pF to maintain tpd ≤ 11 ns (VCCI=2.5 V/VCCO=5.0 V); for non-critical control lines, 120 pF is supported with predictable delay penalty.

Is 74AXP1T32 qualified for automotive applications?

No. This part is specified for industrial temperature range (–40 °C to +85 °C) and carries no AEC-Q200 qualification. Nexperia does not list it in automotive-grade product families, and the datasheet explicitly excludes automotive use per Section 15 Legal Information.
