Nexperia USA Inc. NXU0204PWJ

Overview

NXU0204PWJ from Nexperia is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs, enabling bidirectional asynchronous bus translation between independent 0.9 V–5.5 V domains. It supports fixed-direction data flow (A→B on three channels, B→A on one), features integrated 6.5 MΩ input pull-down resistors, IOFF partial power-down protection, and operates across –40 °C to +125 °C for industrial embedded interfaces.

For engineers reviewing the NXU0204PWJ datasheet, NXU0204PWJ pinout, NXU0204PWJ application, or NXU0204PWJ equivalent, key selection criteria include its dual-rail supply flexibility (VCCA/VCCB = 0.9–5.5 V), Schmitt-trigger noise immunity for slow/noisy signals, 250 Mbps max data rate (≥1.8 V), 12 mA output drive at 5 V, and suspend-mode behavior during supply loss.

Technical Context

The NXU0204PWJ implements four independent level-shifting channels with asymmetric directionality: A1/A2/YB1/YB2 support unidirectional A-to-B translation, while B3/B4/YA3/YA4 enable B-to-A translation. Its Schmitt-trigger inputs provide hysteresis (e.g., 0.96 V typ at 5.5 V) and tolerate slow edges without oscillation.

IOFF circuitry actively blocks backflow current when either VCCA or VCCB drops below 100 mV or floats, ensuring safe partial power-down. The OE input is referenced to either supply domain and drives outputs into high-impedance state without requiring supply sequencing - eliminating power-up/down glitches.

FAQ

Can NXU0204PWJ translate between 1.2 V and 5.0 V simultaneously?

Yes. VCCA can be set to 1.2 V (for A-side inputs A1/A2 and outputs YA3/YA4), while VCCB is set to 5.0 V (for B-side inputs B3/B4 and outputs YB1/YB2). The device fully supports this cross-domain translation with verified 250 Mbps data rate and 0.96 V hysteresis at 5.0 V, meeting JEDEC JESD8-12 and JESD12-6 standards.

Is external pull-up required on Schmitt-trigger inputs?

No. Each input includes an integrated 6.5 MΩ pull-down resistor that prevents floating states and ensures defined logic levels without external components. An external pull-up may be added only if needed for specific logic polarity, but must be ≤1 MΩ to avoid contention with the internal resistor.

What happens to outputs when VCCA is powered but VCCB is disconnected?

When VCCB floats or drops below 100 mV, the device enters suspend mode: all outputs (YB1/YB2/YA3/YA4) transition to high-impedance state, and IOFF circuitry blocks backflow current from VCCA into the unpowered VCCB domain. This behavior is guaranteed per datasheet Section 8.4 and Figure 8.

Does OE need to be driven from the same supply domain as its associated outputs?

No. OE is referenced to either VCCA or VCCB via internal VCC(MIN) circuitry. It can be driven from either supply domain - e.g., OE tied to VCCA while controlling YB1/YB2 outputs referenced to VCCB - enabling flexible PCB routing without level-shifting the enable signal.
