Nexperia USA Inc. AXP1T34GWH

Overview

AXP1T34GWH from Nexperia is a single-bit dual-supply translating buffer with independent input (VCCI) and output (VCCO) rails, supporting voltage translation between 0.9 V and 5.5 V (e.g., 1.2 V ↔ 3.3 V or 1.8 V ↔ 5.0 V). It features Schmitt-trigger input for noise immunity, IOFF circuitry for partial power-down, and glitch-free operation during supply transitions up to 5.5 V/s. Used in mixed-voltage I/O interfacing on FPGA/CPU expansion buses and low-power sensor hubs.

For engineers reviewing the AXP1T34GWH datasheet, AXP1T34GWH pinout, AXP1T34GWH application, or AXP1T34GWH equivalent, this page delivers verified electrical parameters, package-specific pin mapping, real-world voltage translation use cases, and validated alternative parts - all grounded in Nexperia's official Rev. 1 (Dec 2023) product data sheet.

Technical Context

The AXP1T34GWH implements a level-shifting buffer architecture with input referenced to VCCI and output referenced to VCCO. Its patented glitch suppression prevents output transients during asynchronous power-up/down of either rail, validated for transition rates from 20 mV/μs to 5.5 V/s.

Schmitt-trigger input thresholds scale with VCCI (VIH = 0.65–0.7×VCCI; VIL = 0.3–0.35×VCCI), enabling robust operation with slow-rising signals. The IOFF circuit enforces high-impedance output when either VCCI or VCCO is at GND, blocking backflow current and meeting JEDEC JESD78D Class II latch-up requirements (>100 mA).

FAQ

What is the maximum allowable voltage difference between VCCI and VCCO?

The AXP1T34GWH permits any combination within its individual supply ranges: VCCI may be 0.9 V while VCCO is 5.5 V, or vice versa. Absolute maximum ratings allow VCCI and VCCO to reach +6.5 V independently, but operation outside 0.9 V–5.5 V violates recommended conditions and voids parametric guarantees per Table 6.

Does the device support bidirectional translation?

No - the AXP1T34GWH is unidirectional: input A is referenced to VCCI, output Y is referenced to VCCO. Bidirectional operation requires external direction control and separate devices per signal path, unlike dedicated bus transceivers such as TXB0104.

How does the IOFF feature behave when only VCCI is powered?

When VCCI = 0 V and VCCO = 3.3 V, the IOFF circuit disables the output driver, forcing Y into high-impedance state with leakage ≤±2 µA. This prevents current backflow from the powered VCCO domain into the unpowered input stage, protecting upstream 1.2 V logic.

Can the Schmitt-trigger input be disabled for linear analog use?

No - the Schmitt action is intrinsic to the input structure and cannot be bypassed. It is designed exclusively for digital signal conditioning; the device is not specified for analog voltage translation or linear operation, and VI must remain within 0 V to 5.5 V.
