Product details
Overview
NTB0101GW-Q100 from NXP Semiconductors is an automotive-grade 1-bit dual-supply bidirectional voltage-level translating transceiver with auto-direction sensing and 3-state output control. It supports VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V, enabling translation between 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V domains. Its IOFF circuitry enables partial power-down operation, and it is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and ADAS sensor interfaces.
For engineers reviewing the NTB0101GW-Q100 datasheet, NTB0101GW-Q100 pinout, NTB0101GW-Q100 application, or NTB0101GW-Q100 equivalent, key selection considerations include its auto-direction sensing architecture, asymmetric supply range support, IOFF-enabled power-down behavior, high-impedance OFF-state under OE control, and automotive temperature qualification - all critical for mixed-voltage CAN/LIN subsystems and microcontroller-to-peripheral interfacing.
Technical Context
The NTB0101GW-Q100 implements a self-sensing bidirectional I/O cell using one-shot edge-detection circuits that dynamically enable PMOS or NMOS drive transistors during signal transitions - eliminating need for external direction control. Its dual-supply architecture isolates A-port logic (VCC(A)-referenced) from B-port logic (VCC(B)-referenced), with OE referenced solely to VCC(A).
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) drops to GND, preventing backflow current during partial power-down. Input clamping and ESD protection are asymmetric: B port exceeds 15 kV HBM/Class 3B, while A port meets 2.5 kV HBM/Class 2 - reflecting its role as low-voltage interface node.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-port logic and OE input; sets minimum system voltage for low-voltage domain (e.g., 1.2 V/1.5 V/1.8 V MCUs) |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic; supports legacy 3.3 V/5.0 V peripherals and sensors without level-shifting buffers |
| Propagation Delay (A→B) | 0.8–15.9 ns - varies with VCC(A)/VCC(B) and temperature; enables >40 Mbps data rate at −40 °C to +125 °C |
| IOFF Leakage Current | ±2 µA max (−40 °C to +125 °C) - ensures safe isolation during partial power-down of either supply rail |
| ESD Protection (B port) | HBM Class 3B (>15 kV) - robustness against handling discharge in automotive assembly environments |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and body-control module deployment |
| Input Capacitance (B port) | 7.5 pF typical - limits capacitive loading on high-speed 5 V buses (e.g., LIN transceivers, sensor ADCs) |
Pinout & Package
NTB0101GW-Q100 is housed in a 6-pin SC-88 (SOT363) plastic surface-mount package measuring 2.2 mm × 1.8 mm × 1.15 mm, optimized for space-constrained automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply voltage A | Power source for A-port I/O and OE input; must be ≤ VCC(B) in active mode |
| GND | Ground reference | Common 0 V reference for both supply domains and signal integrity |
| A | Data I/O (VCC(A)-referenced) | Bidirectional data path for low-voltage domain (e.g., 1.8 V MCU GPIO) |
| B | Data I/O (VCC(B)-referenced) | Bidirectional data path for higher-voltage domain (e.g., 5 V sensor interface) |
| OE | Output enable (active HIGH) | Controls 3-state output; referenced to VCC(A); tie to GND via pull-down for power-up safety |
| VCC(B) | Supply voltage B | Power source for B-port I/O; supports up to 5.5 V for compatibility with legacy automotive loads |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external direction-control signal and associated routing; reduces BOM count and layout complexity in bidirectional UART/SPI links |
| Asymmetric supply support | Enables direct interfacing between 1.2 V SoCs and 5.0 V analog front-ends without intermediate regulators or discrete FET translators |
| IOFF partial power-down | Prevents damaging back-current when VCC(A) or VCC(B) is unpowered - critical for hot-plug diagnostics and sleep-mode battery conservation |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C, meeting automotive powertrain and chassis system reliability requirements |
| High-BWM ESD on B port | 15 kV HBM rating protects against electrostatic discharge during vehicle assembly and field service without external TVS diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NTS0101GW-Q100 | Open-drain architecture; no auto-direction sensing; requires external pull-ups; lower drive strength | Better suited for I²C and 1-Wire where bidirectional open-drain is required | Select NTS0101GW-Q100 only when protocol mandates open-drain behavior; NTB0101GW-Q100 is superior for push-pull UART/SPI |
| TXS0101QPWRQ1 | Texas Instruments part; similar auto-direction function but wider VCC(A) range (1.65–3.6 V); no AEC-Q100 Grade 1 rating | Limited to industrial temperature range (−40 °C to +85 °C); not qualified for powertrain use | Choose TXS0101QPWRQ1 only for non-safety-critical cabin electronics where automotive qualification is not mandated |
Compared with NTS0101GW-Q100 and TXS0101QPWRQ1, the NTB0101GW-Q100 uniquely combines AEC-Q100 Grade 1 qualification, true push-pull auto-direction operation, and asymmetric 1.2 V–5.5 V supply support - making it the only option validated for engine bay and ADAS sensor interface applications requiring guaranteed performance across full automotive temperature range.

FAQ
What is the maximum data rate supported by the NTB0101GW-Q100?
The NTB0101GW-Q100 supports up to 100 Mbps at 3.3 V/5.0 V supplies and −40 °C to +85 °C, and maintains ≥40 Mbps operation across its full AEC-Q100 Grade 1 temperature range (−40 °C to +125 °C). This is verified by pulse-width and propagation delay specifications in Tables 10–12 of the official datasheet, with fdata = 40 Mbps guaranteed at +125 °C.
Can NTB0101GW-Q100 operate with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes, the NTB0101GW-Q100 is fully specified for simultaneous operation at VCC(A) = 1.2 V and VCC(B) = 5.0 V. Table 6 confirms this combination falls within recommended operating conditions, and dynamic characteristics in Table 10 show tpd = 4.2 ns (A→B) and fdata = 80 Mbps at those voltages and 25 °C.
Does NTB0101GW-Q100 require external pull-up or pull-down resistors on the A or B ports?
No - external pull-up or pull-down resistors are not required and are discouraged. The NTB0101GW-Q100 has internal weak pull resistors (4 kΩ) and is designed for capacitive-load-only operation. Section 13.6 explicitly states pull-up/down resistors must exceed 50 kΩ to avoid contention, and recommends against use in open-drain protocols like I²C.
How does the IOFF feature protect the NTB0101GW-Q100 during partial power-down?
The IOFF circuitry in NTB0101GW-Q100 disables outputs and blocks current flow when either VCC(A) or VCC(B) drops to GND, limiting IOFF leakage to ±2 µA max over temperature. This prevents damaging backflow current from an active supply into a powered-down domain - a critical safeguard in automotive systems with staggered power-rail sequencing.
Is the OE pin of NTB0101GW-Q100 compatible with 1.2 V logic levels when VCC(A) = 1.2 V?
Yes - OE is referenced to VCC(A), and VIH(OE) = 0.65 × VCC(A) min (Table 9). At VCC(A) = 1.2 V, VIH(OE) = 0.78 V, which is compatible with standard 1.2 V CMOS logic. VOL(OE) is ≤ 0.35 × VCC(A) = 0.42 V, ensuring clean LOW recognition by 1.2 V drivers.
