Product details
Overview
NXB0104BQ-Q100 from Nexperia is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in DHVQFN14 package, supporting VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V, with IOFF partial power-down protection and AEC-Q100 Grade 1 qualification for automotive infotainment and ADAS domain controllers.
For engineers reviewing the NXB0104BQ-Q100 datasheet, NXB0104BQ-Q100 pinout, NXB0104BQ-Q100 application, or NXB0104BQ-Q100 equivalent, key selection criteria include auto-direction sensing capability, asymmetric supply range compatibility, IOFF-enabled safe power sequencing, and DHVQFN14 side-wettable flank support for AOI-verified solder joints in high-reliability automotive PCBs.
Technical Context
The device implements edge-triggered one-shot circuitry per I/O channel to accelerate signal transitions without external direction control-rising edges activate PMOS drivers (T1/T3), falling edges activate NMOS drivers (T2/T4). Output impedance varies with VCCO: ~70 Ω at 1.2–1.8 V, ~50 Ω at 1.8–3.3 V, and ~40 Ω at 3.3–5.0 V.
It operates in two distinct modes: active translation (OE HIGH) with bidirectional data flow determined by bus activity, and 3-state high-impedance (OE LOW) with IOFF clamping to prevent backflow current during partial power-down. VCC(A) must be ≤ VCC(B) for functional operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports interface between 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic domains on A-side |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to 1.8 V/2.5 V/3.3 V/5.0 V systems on B-side |
| Propagation Delay | 0.8–12.9 ns (A↔B) - ensures sub-13 ns latency across full temp and voltage range (-40 °C to +125 °C) |
| Data Rate | Up to 100 Mbps - supports high-speed serial links like I²C fast-mode+, SPI, and GPIO expansion buses |
| IOFF Leakage | ±2 μA max at -40 °C to +125 °C - guarantees safe isolation when either supply is powered down |
| ESD Robustness | HBM: 2.5 kV (A-port), 15 kV (B-port); CDM: 1 kV - meets stringent automotive ESD immunity requirements |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood and cockpit electronics per AEC-Q100 Grade 1 |
Pinout & Package
DHVQFN14 (SOT762-1), 2.5 × 3.0 × 0.85 mm body, side-wettable flanks for automated optical inspection of solder joints; thermal pad (pin 1 index area) electrically isolated unless connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (1) | Ground reference | 0 V return path for both supply domains; thermal pad may be floated or tied to GND |
| OE (12) | Output enable | Active-HIGH control referenced to VCC(A); drives all A/B ports into high-Z when LOW |
| VCC(B) (11) | B-side supply | Powers B-port I/O cells and internal one-shots; must be ≥ VCC(A) |
| B1–B4 (7–10) | B-side I/O | Bidirectional data terminals referenced to VCC(B); tolerate up to 5.5 V input |
| A1–A4 (2–5) | A-side I/O | Bidirectional data terminals referenced to VCC(A); accept inputs up to VCC(A) + 0.5 V |
| VCC(A) (1) | A-side supply | Powers A-port I/O cells and OE input; sets input threshold at ~VCC(A)/2 |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals-data flow direction inferred from bus edge activity |
| Asymmetric dual-supply operation | Independent VCC(A) and VCC(B) rails allow interfacing between mismatched voltage domains (e.g., 1.2 V MCU ↔ 5 V sensor) |
| IOFF partial power-down | Prevents damaging back-current when one supply is off; leakage limited to ±2 μA over full temperature range |
| Side-wettable flanks | DHVQFN14 package enables automated optical inspection of solder joint quality-critical for automotive zero-defect manufacturing |
| AEC-Q100 Grade 1 | Qualified for automotive applications operating from −40 °C to +125 °C ambient, including engine control and ADAS modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-supply translating transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E-Q1 | 4-bit, auto-direction, VCCA=1.65–3.6 V, VCCB=2.3–5.5 V; no side-wettable flanks; lower ESD (HBM 8 kV B-port) | Not AEC-Q100 qualified; rated only to +85 °C ambient; lacks IOFF specification for partial power-down | Use where cost sensitivity outweighs automotive qualification and extended temperature needs. |
| NXBV0104BQ-Q100 | Same pinout and function but with enhanced B-port ESD (15 kV HBM) and improved tpd consistency across VCC combinations | Identical AEC-Q100 Grade 1 rating and DHVQFN14 package; optimized for high-noise camera/sensor interfaces | Select when higher B-port ESD immunity or tighter skew (<0.2 ns) is required in ADAS vision systems. |
Compared with TXS0104E-Q1, NXB0104BQ-Q100 delivers guaranteed automotive qualification, IOFF-enabled power sequencing, and superior B-port ESD robustness-making it suitable for safety-critical domains where TXS0104E-Q1 falls short. NXBV0104BQ-Q100 offers marginal performance gains but identical form/fit/function for upgrade paths requiring higher noise immunity.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B)?
VCC(A) must be less than or equal to VCC(B) per datasheet Section 7 and Table 6. No maximum differential is specified, but VCC(A) > VCC(B) violates absolute maximum ratings and risks latch-up or permanent damage. Valid configurations include 1.8 V/3.3 V, 1.2 V/5.0 V, and 2.5 V/3.3 V-always ensuring VCC(A) ≤ VCC(B).
Can NXB0104BQ-Q100 translate between 1.2 V and 5.0 V without external components?
Yes. With VCC(A) = 1.2 V and VCC(B) = 5.0 V, the device fully supports bidirectional translation: A-port inputs tolerate up to 1.7 V (VCC(A)+0.5 V), and B-port inputs accept up to 5.5 V. No pull-ups, resistors, or direction-control logic are needed-the auto-sensing architecture handles all edge cases within spec.
How does the IOFF circuit protect during partial power-down?
The IOFF circuit disables output drivers and clamps I/O pins to prevent back-current when either VCC(A) or VCC(B) is at 0 V. Measured leakage is ≤±2 μA over −40 °C to +125 °C (Table 9), ensuring negligible battery drain in sleep-mode automotive modules-meeting ISO 16750-2 quiescent current requirements.
Is the DHVQFN14 package compatible with standard reflow profiles?
Yes. SOT762-1 (DHVQFN14) is qualified for JEDEC J-STD-020 moisture sensitivity level 3 and supports standard lead-free reflow profiles (peak 260 °C). Side-wettable flanks are compatible with automated optical inspection systems using 5-micron resolution imaging-no special stencil or process adjustments required for automotive-grade assembly.
