Nexperia USA Inc. NXU0104PW-Q100J

Overview

NXU0104PW-Q100 from Nexperia is a 4-bit unidirectional dual-supply voltage level translating buffer with Schmitt-trigger inputs, 3-state outputs, AEC-Q100 Grade 1 qualification, 0.9 V to 5.5 V dual supply range (VCCA/VCCB), and 250 Mbps max data rate for ≥1.8 V to 5 V translation. It enables robust I/O translation between automotive domain controllers operating at mismatched voltages (e.g., 1.8 V MCU to 3.3 V sensor interface).

For engineers reviewing the NXU0104PW-Q100 datasheet, NXU0104PW-Q100 pinout, NXU0104PW-Q100 application, or NXU0104PW-Q100 equivalent, key selection criteria include dual-rail voltage flexibility, Schmitt-trigger noise immunity on A-side inputs, OE-referenced-to-either-supply capability, IOFF partial power-down protection, and TSSOP14 package suitability for space-constrained automotive PCBs.

Technical Context

This device implements asynchronous unidirectional level translation from A-bus (inputs A1–A4 referenced to VCCA) to B-bus (outputs YB1–YB4 referenced to VCCB), with no internal direction control logic. The integrated Schmitt-trigger input stage provides 0.25 V to 1.18 V hysteresis (VH) across supply ranges, enabling reliable operation with slow-rising or noisy signals.

Output enable (OE) is referenced to either VCCA or VCCB via internal VCC(MIN) circuitry; asserting OE low places all YBn outputs in high-impedance state regardless of supply sequencing. IOFF circuitry actively blocks backflow current when either VCCA or VCCB drops below 100 mV or floats, eliminating need for external isolation during power transitions.

FAQ

Can NXU0104PW-Q100 translate bidirectionally between VCCA and VCCB?

No. The NXU0104PW-Q100 is strictly unidirectional: data flows only from A-side inputs (A1–A4) to B-side outputs (YB1–YB4). It lacks internal direction control or bus-hold circuitry required for true bidirectional translation. For bidirectional applications, Nexperia's NXU0108 or NXU0116 series should be evaluated.

What happens if OE is left floating during power-up?

The OE pin is float-safe: when left unconnected, internal circuitry pulls it to a logic LOW state, forcing all YBn outputs into high-impedance mode. This ensures bus isolation during power sequencing - a critical feature for preventing glitches or contention in multi-rail automotive systems before firmware initializes.

Does the Schmitt-trigger input require external pull-up or pull-down resistors?

No external resistors are required. Each A-input has an integrated 6.5 MΩ pull-down resistor that prevents undefined states. If an external pull-up is used (e.g., for open-drain compatibility), it must be ≤1 MΩ to avoid contention with the internal pull-down and ensure correct threshold behavior.

How does IOFF protection behave when VCCA = 0 V and VCCB = 3.3 V?

When VCCA = 0 V (or <100 mV) and VCCB = 3.3 V, the device enters suspend mode: all YBn outputs go high-impedance, and IOFF circuitry limits back-current from VCCB through YBn pins to ≤±2 μA. This prevents damage to the powered-down A-side MCU and maintains signal integrity on the active B-side bus.
