Nexperia USA Inc. NXU0204GU12-Q100X

Overview

NXU0204GU12-Q100 from Nexperia is a 4-bit dual-supply voltage level translating buffer with Schmitt-trigger inputs and 3-state outputs, designed for bidirectional asynchronous bus translation between A- and B-side domains (e.g., 1.2 V ↔ 3.3 V). It supports unidirectional data flow-A→B on three channels and B→A on one channel-with independent VCCA (0.9–5.5 V) and VCCB (0.9–5.5 V) supplies, IOFF protection, and automotive-grade AEC-Q100 Grade 1 qualification (-40 °C to +125 °C).

For engineers reviewing the NXU0204GU12-Q100 datasheet, NXU0204GU12-Q100 pinout, NXU0204GU12-Q100 application, or NXU0204GU12-Q100 equivalent, key selection considerations include dual-rail supply flexibility, Schmitt-trigger noise immunity for slow/noisy signals, 250 Mbps max data rate (≥1.8 V), 12 mA output drive at 5 V, and XQFN12 package compatibility with automated optical inspection.

Technical Context

The device implements a fixed-direction translation architecture: A1/A2/YA3/YA4 interface the A-bus (VCCA-referenced), while B3/B4/YB1/YB2 interface the B-bus (VCCB-referenced), enabling asymmetric voltage translation across four channels. OE is referenced to either VCCA or VCCB via internal VCC(MIN) circuitry, supporting flexible power-up sequencing.

Integrated 6.5 MΩ pull-down resistors on all inputs ensure defined logic states during floating conditions, and Schmitt-trigger hysteresis (e.g., 0.96 V typ at 5.5 V) provides robust noise rejection for slow edges. IOFF circuitry actively blocks backflow current when either supply drops below 100 mV or floats, eliminating need for external isolation in partial-power-down systems.

Key Specifications

Pinout & Package

XQFN12 package (SOT1174-1): 1.70 × 2.0 × 0.50 mm, 12-terminal, no leads, side-wettable flanks for AOI-compatible solder joint inspection. Exposed thermal pad (GND(1)) is electrically isolated; if soldered, must remain floating or connect to GND.

FAQ

Can NXU0204GU12-Q100 translate between 1.2 V and 5.0 V simultaneously?

Yes. VCCA can be set to 1.2 V (powering A1, A2, YA3, YA4) while VCCB is set to 5.0 V (powering B3, B4, YB1, YB2), enabling direct translation without intermediate voltage rails. The device supports all combinations within 0.9–5.5 V per supply, including 1.2 V ↔ 5.0 V, with verified 250 Mbps performance at ≥1.8 V translation.

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 OFF-state, and IOFF circuitry blocks back-current flow from VCCA into the unpowered VCCB domain. This protects downstream 5 V circuitry from latch-up or damage during partial power-down sequences.

Is OE required to be pulled to a specific supply rail?

No. OE is referenced to either VCCA or VCCB via internal VCC(MIN) circuitry, allowing direct connection to either supply or to ground. It can also be left floating-the internal design ensures outputs default to high-impedance during power-up/down, eliminating need for external pull resistors in most automotive reset scenarios.

Does the XQFN12 package support reflow soldering with standard lead-free profiles?

Yes. The SOT1174-1 XQFN12 package is qualified for standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260 °C. Its side-wettable flanks enable automated optical inspection of solder fillets, and the 0.50 mm profile supports ultra-thin automotive PCB stacks without mechanical interference.
