Product details
Overview
NTB0104UK-Q100 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), supporting VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V, with IOFF partial power-down protection and 3-state outputs. It enables seamless interfacing between mixed-voltage automotive subsystems such as 1.8 V microcontrollers and 3.3 V sensors.
For engineers reviewing the NTB0104UK-Q100 datasheet, NTB0104UK-Q100 pinout, NTB0104UK-Q100 application, or NTB0104UK-Q100 equivalent, key selection criteria include its auto-direction sensing architecture, guaranteed 40 Mbps data rate at −40 °C to +125 °C, ultra-low OFF-state leakage (±1 μA), WLCSP12 package footprint (1.20 × 1.60 × 0.56 mm), and AEC-Q100 qualification for under-hood use.
Technical Context
The NTB0104UK-Q100 implements an edge-triggered auto-direction sensing architecture using dual one-shot circuits per I/O channel-PMOS for low-to-high acceleration and NMOS for high-to-low acceleration-enabling transparent bidirectional translation without external direction control. Its I/O cells feature dynamic output impedance scaling: ~70 Ω at VCCO = 1.2–1.8 V, ~50 Ω at 1.8–3.3 V, and ~40 Ω at 3.3–5.0 V.
IOFF circuitry actively disables outputs during partial power-down, blocking damaging backflow current when either VCC(A) or VCC(B) is at GND. Inputs tolerate up to 5.5 V regardless of supply, and the device supports asynchronous operation across both voltage domains with no power-up sequencing requirement-either supply may ramp first.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side I/Os and OE input; enables interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; supports 1.8 V/2.5 V/3.3 V/5.0 V domains including legacy automotive peripherals |
| Data Rate | 40 Mbps at −40 °C to +125 °C - verified minimum throughput for CAN FD auxiliary signal routing and sensor fusion buses |
| Propagation Delay | A→B: 0.8–15.9 ns, B→A: 0.3–17.2 ns - bounded worst-case delay ensures timing closure in 25 MHz SPI clock domain bridging |
| IOFF Leakage | ±1 μA at full temperature range - prevents battery drain in always-on automotive modules during sleep mode |
| ESD Robustness | B-port: >15 kV HBM, >15 kV MIL-STD-883 Class 3B - withstands assembly handling and in-vehicle ESD events per ISO 10605 |
| Package | WLCSP12 (1.20 × 1.60 × 0.56 mm) - enables ultra-compact placement on space-constrained ADAS camera modules and body control units |
Pinout & Package
NTB0104UK-Q100 uses a wafer-level chip-scale package (WLCSP12) with 12 solder bumps, body size 1.20 × 1.60 × 0.56 mm, and backside coating. Pin mapping follows JEDEC-standard ball grid layout with no NC pins electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply reference for A-side I/Os and OE | Must be ≤ VCC(B); powers internal level-shifting circuitry and defines A-port logic thresholds |
| A1–A4 | Bi-directional data port (A-side) | Referenced to VCC(A); accepts inputs up to 5.5 V; auto-senses direction based on edge transitions |
| OE | Active-HIGH output enable | Referenced to VCC(A); LOW forces all I/Os into high-impedance state; pull-down recommended for power-up safety |
| GND | Common ground reference | Single ground connection required; substrate pad must remain floating or tied to GND (no electrical requirement to solder) |
| B1–B4 | Bi-directional data port (B-side) | Referenced to VCC(B); drives outputs compliant with B-side supply; supports 5.0 V-tolerant inputs |
| VCC(B) | Supply reference for B-side I/Os | Enables translation to higher-voltage domains; must be ≥ VCC(A) during active operation |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals-reduces PCB routing complexity and MCU GPIO count in bidirectional buses |

| Ultra-low static leakage | ±1 μA OFF-state current at +125 °C ensures <1 μA system sleep current contribution in always-on telematics modules |
| AEC-Q100 Grade 1 | Qualified for under-hood operation (−40 °C to +125 °C ambient), including thermal cycling and humidity testing per automotive reliability standards |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NTB0104BQ-Q100 | DHVQFN14 package (2.5 × 3.0 × 0.85 mm); same electrical specs and AEC-Q100 Grade 1 rating | Suitable for reflow-compatible layouts requiring larger pitch (0.5 mm) and thermal pad for higher-power dissipation | Select when board assembly uses standard QFN pick-and-place; not drop-in compatible with WLCSP footprint |
| TXS0104E-Q1 | Texas Instruments part; 4-bit, auto-direction, VCCA = 1.2–3.6 V, VCCB = 1.65–5.5 V; AEC-Q100 Grade 1 qualified | Higher typical propagation delay (up to 22 ns) and lower max data rate (33 Mbps at +125 °C) | Acceptable for non-critical timing paths where footprint compatibility is secondary to second-source availability |
Compared with NTB0104UK-Q100, the NTB0104BQ-Q100 offers identical functionality in a thermally enhanced QFN package ideal for higher-current applications, while TXS0104E-Q1 provides a functionally similar but slower alternative with broader distributor stock-neither is pin-compatible due to differing package geometries and bump layouts.

FAQ
What is the maximum data rate supported by NTB0104UK-Q100 over its full operating temperature range?
The NTB0104UK-Q100 guarantees a minimum data rate of 40 Mbps across −40 °C to +125 °C ambient, validated per Table 11 and Table 12 of the datasheet. At 25 °C, it achieves up to 100 Mbps depending on supply voltages-e.g., 100 Mbps at VCC(A) = 3.3 V and VCC(B) = 5.0 V. This makes NTB0104UK-Q100 suitable for high-speed sensor data aggregation in modern automotive ECUs.
Can NTB0104UK-Q100 translate between 1.2 V and 5.0 V logic levels while maintaining AEC-Q100 compliance?
Yes. The NTB0104UK-Q100 is explicitly rated for VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V, and its AEC-Q100 Grade 1 qualification covers the full −40 °C to +125 °C range under these conditions. Electrical parameters-including VOL, VOH, tpd, and IOFF-are fully characterized at 1.2 V/5.0 V operation, confirming NTB0104UK-Q100 meets automotive reliability requirements for this voltage pair.
Does NTB0104UK-Q100 require external pull-up or pull-down resistors on its I/O lines?
No. The NTB0104UK-Q100 features internally biased I/O cells optimized for capacitive loads up to 70 pF. External pull-up/pull-down resistors are discouraged unless required by system-level noise immunity needs-and if used, must exceed 50 kΩ to avoid contention. The datasheet explicitly states NTB0104UK-Q100 is not recommended for open-drain protocols like I²C; for those, NTS0104-Q100 is specified instead.
How does the IOFF circuitry in NTB0104UK-Q100 protect against backflow current during partial power-down?
The IOFF circuitry in NTB0104UK-Q100 actively disables all output drivers when either VCC(A) or VCC(B) drops to GND, blocking reverse current paths that could damage upstream or downstream devices. Measured IOFF leakage remains ≤±1 μA across −40 °C to +125 °C, ensuring minimal battery drain in always-on automotive modules-even during extended sleep modes where only one supply remains active.
Is the WLCSP12 package of NTB0104UK-Q100 compatible with standard SMT reflow processes?
Yes. The NTB0104UK-Q100 WLCSP12 package (1.20 × 1.60 × 0.56 mm) is qualified for lead-free reflow per J-STD-020, with peak temperature tolerance up to 260 °C. Its solder bumps use standard SnAgCu alloy, and the backside coating ensures mechanical stability during thermal cycling. Board design must follow NXP's recommended land pattern (SOT1118) and stencil aperture guidelines to ensure reliable solder joint formation.
