Product details
Overview
NTB0102GF,115 from NXP Semiconductors is a 2-bit dual-supply voltage-level translating transceiver with auto-direction sensing and 3-state outputs. It enables bidirectional translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains, supports ±2 mA input drive, features IOFF partial power-down protection, and operates across –40 °C to +125 °C for industrial interface bridging.
For engineers reviewing the NTB0102GF,115 datasheet, NTB0102GF,115 pinout, NTB0102GF,115 application, or NTB0102GF,115 equivalent, this device is critical for low-power, high-speed bidirectional level translation in mixed-voltage SoC interconnects, sensor hubs, and FPGA I/O expansion where automatic direction control eliminates external control logic.
Technical Context
The NTB0102GF,115 implements an edge-detecting one-shot architecture per I/O channel to dynamically enable PMOS/NMOS drivers during signal transitions-accelerating rise/fall times without requiring direction-control pins. Its weak static output drive (70 Ω at 1.2–1.8 V, 50 Ω at 1.8–3.3 V) allows external bus drivers to override outputs during reverse-direction data flow.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, blocking damaging backflow current during partial power-down. Input clamping and ESD protection (15 kV HBM on B port, 2.5 kV on A port) ensure robustness in noisy industrial environments.
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; must be ≤ VCC(B) in active operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/Os; supports legacy 5 V logic interfacing |
| Propagation Delay | 0.8–12.9 ns (A↔B) - enables >40 Mbps data rate at full temperature range |
| IOFF Leakage | ±2 μA max at –40 °C to +125 °C - prevents back-current during asymmetric power-down |
| ESD Protection | HBM Class 3B (15 kV) on B port, Class 2 (2.5 kV) on A port - meets IEC 61000-4-2 system-level immunity requirements |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive and industrial control applications |
| Input Drive Req. | ±2 mA minimum - ensures reliable edge detection for auto-direction sensing |
Pinout & Package
NTB0102GF,115 uses the SOT1089 XSON8 package: 1.35 mm × 1.0 mm × 0.5 mm body, no leads, 8-terminal exposed pad design optimized for space-constrained PCB layouts and thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data I/O (VCC(A)-referenced) | Bidirectional signals tied to low-voltage domain (e.g., 1.8 V MCU); auto-sensed direction |
| B1, B2 | Data I/O (VCC(B)-referenced) | Bidirectional signals tied to higher-voltage domain (e.g., 3.3 V/5 V peripheral); withstands 5.5 V inputs |
| OE | Output Enable (active HIGH, VCC(A)-referenced) | Drives all I/Os into high-impedance state; pull-down required for safe power-up |
| VCC(A) | Supply A | Powers A-side logic and OE input; must be ≤ VCC(B) during operation |
| VCC(B) | Supply B | Powers B-side logic; enables translation up to 5.5 V |
| GND | Ground | Common reference for both domains; required for IOFF and ESD clamp return path |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals, reducing routing complexity and GPIO count in SoC-to-peripheral links |
| IOFF partial power-down | Prevents back-current when either supply is off-enables hot-swap capability and safe multi-rail sequencing |
| Wide VCC(A)/VCC(B) range | Supports direct translation between 1.2 V ASIC cores and 5 V legacy interfaces without intermediate regulators |
| Low dynamic power | CPD as low as 0.01 pF (disabled) and 18 pF (B port active) minimizes switching power in battery-powered sensor nodes |
| High-temp reliability | Specified up to +125 °C with <0.5 ns output skew ensures timing integrity in engine control units and motor drives |

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 |
|---|---|---|---|
| TXS0102DR | TI part with 1.65–3.6 V VCCA/VCCB range; lacks IOFF; 5 V-tolerant B-port inputs only up to 3.6 V | Not suitable for 5 V peripheral interfacing; requires external pull-ups for open-drain compatibility | Select NTB0102GF,115 when 5 V tolerance, IOFF, or –40 °C to +125 °C operation is required |
| NTB0102GT,115 | Same die, identical specs, but SOT833-1 package (1.0 mm × 1.95 mm × 0.5 mm); 0.25 mm larger width than SOT1089 | Compatible footprint with NTB0102GF,115 but slightly different land pattern due to terminal placement | Choose NTB0102GF,115 for tighter board area constraints where 1.35 mm × 1.0 mm footprint is critical |
Compared with TXS0102DR and NTB0102GT,115, the NTB0102GF,115 delivers unique 5 V-tolerant B-port inputs, guaranteed IOFF behavior across full temperature range, and the smallest XSON8 footprint-making it optimal for space- and reliability-critical mixed-voltage interfaces.

FAQ
What is the maximum data rate supported by NTB0102GF,115?
The NTB0102GF,115 supports up to 100 Mbps under optimal conditions (VCC(A) = 3.3 V, VCC(B) = 5.0 V, Tamb = 25 °C). At full operating range (–40 °C to +125 °C), the guaranteed minimum data rate is 40 Mbps, validated by pulse width (tW ≥ 25 ns) and propagation delay specifications in the datasheet.
Can NTB0102GF,115 translate between 1.2 V and 5.0 V domains?
Yes - NTB0102GF,115 explicitly supports VCC(A) = 1.2 V to 3.6 V and VCC(B) = 1.65 V to 5.5 V. Translation between 1.2 V (A-side) and 5.0 V (B-side) is fully specified, including input tolerance (up to 5.5 V on B pins) and output drive capability across the full temperature range.
Is NTB0102GF,115 pin-compatible with other NTB0102 variants?
No - NTB0102GF,115 uses the SOT1089 package (1.35 × 1.0 × 0.5 mm), while NTB0102GT,115 uses SOT833-1 (1.0 × 1.95 × 0.5 mm) and NTB0102DP,125 uses TSSOP8. Though electrically identical, their land patterns differ; NTB0102GF,115 requires its specific footprint per Figure 3 in the datasheet.
Does NTB0102GF,115 require external pull-up resistors on I/O lines?
No - NTB0102GF,115 has weak internal drive strength and is not designed for open-drain buses like I²C. External pull-up/pull-down resistors must exceed 50 kΩ to avoid contention; for I²C or 1-Wire, NXP recommends NTS0102-Q100 instead of NTB0102GF,115.
How does the IOFF feature protect NTB0102GF,115 during partial power-down?
When either VCC(A) or VCC(B) drops to GND, the IOFF circuitry in NTB0102GF,115 actively disables all outputs, limiting OFF-state leakage to ±2 μA max. This prevents damaging backflow current from a powered domain into a powered-down domain - a critical safeguard in modular power architectures.
