Nexperia USA Inc. NXS0104PW-Q100J

Overview

NXS0104PW-Q100 from Nexperia is a 4-bit automotive-qualified dual-supply translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional level translation between 1.65 V–3.6 V (A-side) and 2.3 V–5.5 V (B-side). It supports up to 24 Mbps data rate in push-pull mode, features IOFF partial power-down protection, and operates across −40 °C to +125 °C for use in I²C and 1-wire automotive interfaces.

For engineers reviewing the NXS0104PW-Q100 datasheet, NXS0104PW-Q100 pinout, NXS0104PW-Q100 application, or NXS0104PW-Q100 equivalent, key selection criteria include its auto-sensing direction control, A/B supply voltage independence, IOFF-enabled safe power sequencing, and integrated 10 kΩ pull-up resistors per I/O port.

Technical Context

The NXS0104PW-Q100 implements a switch-type architecture using pass-gate transistors and edge-rate accelerator one-shot circuits to enable voltage translation without external direction control. Each channel includes internal 10 kΩ pull-ups referenced to its respective supply (VCC(A) or VCC(B)), and the gate bias of the pass transistor is set ~1 V_TH above the lower supply rail.

Direction sensing is fully autonomous: rising edges on either side trigger the one-shot circuit, which temporarily bypasses pull-up resistors via PMOS transistors to accelerate output transitions. The one-shot pulse duration (~50 ns) and output impedance (50–70 Ω during acceleration) are fixed and independent of external loading within specified capacitive limits.

FAQ

What is the minimum recommended pull-up resistor value when using external resistors with NXS0104PW-Q100?

The internal 10 kΩ pull-ups are disabled when OE is LOW, so external pull-ups must be sized to meet VOL specifications under maximum sink current (±50 mA). For VCC(B) = 5.0 V and VOL ≤ 0.4 V, a 100 kΩ external resistor yields ~46 μA sink current - acceptable for I²C standard-mode speeds. Lower values (e.g., 2.2 kΩ) are usable but increase static power and reduce noise margin.

Can NXS0104PW-Q100 translate between 1.2 V and 3.3 V domains?

No. VCC(A) must be ≥1.65 V per datasheet specification, so 1.2 V A-side operation is unsupported. Attempting to supply VCC(A) below 1.65 V risks undefined logic thresholds, increased leakage, and failure to meet AEC-Q100 parametric limits. For 1.2 V interfaces, consider the NXV0104-Q100 or discrete FET-based solutions.

How does the one-shot circuit affect signal integrity with heavy capacitive loads?

With >15 pF total load (including trace and connector capacitance), the one-shot's ~50 ns pulse may expire before the output reaches VOH, causing incomplete HIGH transitions and potential bus lockup. Layout best practices require trace lengths <2 cm and avoidance of stubs or connectors exceeding 2 pF to maintain reliable edge acceleration and prevent re-triggering.

Is power supply sequencing required during system startup?

No strict sequencing is required: NXS0104PW-Q100 tolerates VCC(A) ≥ VCC(B) during ramp-up without damage. However, sustained operation requires VCC(A) ≤ VCC(B) to maintain correct pass-gate bias. OE should be held LOW via pull-down until both supplies stabilize to prevent spurious I/O activity during power-on reset.
