Product details
Overview
NTB0102GD-Q100 from NXP Semiconductors is an automotive-qualified 2-bit dual-supply translating transceiver with auto-direction sensing, enabling bidirectional voltage level translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It features two 2-bit I/O ports (A1/A2, B1/B2), active-HIGH output enable (OE), IOFF partial power-down protection, and operates across −40 °C to +125 °C. It is used in automotive infotainment and ADAS domain controllers interfacing low-voltage MCUs with higher-voltage peripherals.
For engineers reviewing the NTB0102GD-Q100 datasheet, NTB0102GD-Q100 pinout, NTB0102GD-Q100 application, or NTB0102GD-Q100 equivalent, key selection criteria include its auto-direction capability, AEC-Q100 Grade 1 qualification, wide dual-rail supply flexibility, IOFF-enabled safe power-down behavior, and XSON8 package suitability for space-constrained automotive PCBs.
Technical Context
The NTB0102GD-Q100 implements weak-output auto-direction architecture: internal one-shot circuits detect signal edges on either port to transiently activate PMOS/NMOS drivers, accelerating transitions without external direction control. Its I/O cells maintain defined static states but allow external drivers to override outputs during bus contention-critical for open-bus systems like CAN or LIN physical layer interfaces.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down. Input clamping and ESD protection exceed 15 kV HBM (Class 3B) on the B port and 2.5 kV on the A port, meeting automotive robustness requirements for under-hood and cockpit electronics.
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; enables interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V logic domains. |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; supports translation to 1.8 V/2.5 V/3.3 V/5.0 V systems including legacy automotive sensors. |
| Propagation Delay (A→B) | 0.8 ns to 15.9 ns - varies with supply voltages and temperature; ensures sub-10 ns typical delay at 3.3 V/5.0 V for high-speed MCU-peripheral links. |
| Data Rate | Up to 100 Mbps - validated at VCC(A)=3.3 V, VCC(B)=5.0 V, −40 °C to +125 °C; suitable for SPI, UART, and fast GPIO bridging. |
| ESD Protection (B port) | HBM JESD22-A114E Class 3B >15,000 V - protects against electrostatic discharge in assembly and field operation per AEC-Q100 stress testing. |
| IOFF Leakage Current | ±10 µA max at −40 °C to +125 °C - limits backfeed current during system sleep modes, preserving battery life in always-on automotive modules. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1; supports engine bay, transmission control, and front radar module environments. |
Pinout & Package
NTB0102GD-Q100 uses the SOT996-2 XSON8 package: plastic extremely thin small outline, no leads, 3 mm × 2 mm × 0.5 mm body, 8 terminals, pin 1 indicator in lower-left corner below marking code "t02".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2, B1 | Data I/O (B-side) | Referenced to VCC(B); bidirectional signals translated from/to A-side; tolerate up to 5.5 V input regardless of VCC(B). |
| GND | Ground reference | Common 0 V return for both supply domains; must be low-impedance connection to avoid noise coupling between rails. |
| VCC(A) | Supply A | Powers A-side I/Os and OE input; must be ≤ VCC(B) during steady-state operation per datasheet constraint. |
| A2, A1 | Data I/O (A-side) | Referenced to VCC(A); accept inputs up to 5.5 V; drive outputs compliant with VCC(A) logic thresholds. |
| OE | Output Enable | Active-HIGH referenced to VCC(A); LOW forces all I/Os into high-impedance OFF-state; requires pull-down for safe power-up. |
| VCC(B) | Supply B | Powers B-side I/Os; enables translation to 5.0 V domains; IOFF activates if VCC(B) = 0 V while VCC(A) is active. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals; edge-detecting one-shot circuitry enables seamless bidirectional data flow on shared buses. |
| IOFF partial power-down | Prevents damaging backflow current when either VCC rail is powered down; critical for modular automotive ECUs with independent subsystem power domains. |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation with full electrical characterization; meets automotive reliability and lifetime requirements. |
| Asymmetric dual-supply support | Independent VCC(A) and VCC(B) rails allow translation between non-matching logic families (e.g., 1.8 V MCU ↔ 5.0 V sensor) without level-shifter ICs or resistive networks. |
| High ESD immunity (B port) | 15 kV HBM Class 3B rating on B-side pins reduces risk of field failure due to handling or environmental discharge in vehicle assembly lines. |

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 |
|---|---|---|---|
| NTB0102DP-Q100 | TSSOP8 package (SOT505-2), 3 mm × 4.4 mm body, gull-wing leads; identical electrical specs and AEC-Q100 qualification. | Better suited for manual rework or wave-soldered automotive assemblies where leaded packages are preferred for inspection and repairability. | Select NTB0102DP-Q100 when board assembly process requires leaded packaging or thermal mass for reflow profile compatibility. |
| TXS0102QPWRQ1 | Texas Instruments part; same 2-bit auto-direction function, AEC-Q100 Grade 1, but wider VCC(A) range (1.65 V–3.6 V) and no 1.2 V support. | Lacks 1.2 V compatibility; unsuitable for next-gen ultra-low-power automotive MCUs operating at 1.2 V core voltage. | Choose TXS0102QPWRQ1 only if existing design already uses TI ecosystem tools and 1.2 V operation is not required. |
Compared with NTB0102DP-Q100, the NTB0102GD-Q100 offers superior board-space efficiency in XSON8, while versus TXS0102QPWRQ1 it uniquely supports 1.2 V A-side operation-enabling direct interface with emerging 1.2 V automotive SoCs without intermediate regulators or level-shifting stages.

FAQ
What is the maximum data rate supported by the NTB0102GD-Q100?
The NTB0102GD-Q100 supports up to 100 Mbps data rate, verified at VCC(A) = 3.3 V and VCC(B) = 5.0 V over the full −40 °C to +125 °C automotive temperature range. This performance enables reliable use in high-speed SPI, UART, and GPIO bridging applications within automotive ECUs without requiring external clock conditioning or signal retiming.
Does the NTB0102GD-Q100 require external direction-control signals?
No, the NTB0102GD-Q100 implements auto-direction sensing using internal edge-detecting one-shot circuits that transiently activate PMOS/NMOS drivers on signal transitions. This eliminates the need for external DIR or control GPIOs, simplifying PCB routing and firmware logic in bidirectional bus interfaces such as those found in automotive domain controllers.
Can the NTB0102GD-Q100 operate with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes, the NTB0102GD-Q100 is fully specified for simultaneous operation at VCC(A) = 1.2 V and VCC(B) = 5.0 V. Its A-port inputs accept up to 5.5 V regardless of VCC(A) level, and its B-port outputs swing rail-to-rail relative to VCC(B), making it ideal for interfacing next-generation 1.2 V MCUs with legacy 5.0 V automotive peripherals.
How does the IOFF feature protect the NTB0102GD-Q100 during partial power-down?
The IOFF circuitry in the NTB0102GD-Q100 disables all outputs and prevents damaging backflow current when either VCC(A) or VCC(B) drops to GND. This ensures safe isolation during subsystem power gating-such as when an infotainment MCU enters deep sleep while its display remains active-without requiring external isolation switches or complex power sequencing.
Is the NTB0102GD-Q100 compatible with I²C or 1-Wire buses?
No, the NTB0102GD-Q100 is not recommended for I²C or 1-Wire applications due to its weak static drive strength and requirement for pull-up/pull-down resistors >50 kΩ. For these open-drain protocols, NXP specifies the NTS0102-Q100 as the appropriate AEC-Q100-qualified alternative, which includes dedicated open-drain optimization and bus arbitration support.
