Product details
Overview
NTB0102GT,115 from NXP Semiconductors is a 2-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XSON8 package. It enables seamless communication between 1.2 V–3.6 V (A-side) and 1.65 V–5.5 V (B-side) domains without external direction control, supports 3-state output via active-HIGH OE, and operates across –40 °C to +125 °C for industrial and automotive interface applications.
For engineers reviewing the NTB0102GT,115 datasheet, NTB0102GT,115 pinout, NTB0102GT,115 application, or NTB0102GT,115 equivalent, key selection criteria include its asymmetric supply flexibility (VCC(A): 1.2–3.6 V / VCC(B): 1.65–5.5 V), IOFF-enabled partial power-down protection, ±1 μA max OFF-state leakage, 40 Mbps min data rate at 125 °C, and 8-terminal XSON8 footprint with 1.0 × 1.95 × 0.5 mm body.
Technical Context
The NTB0102GT,115 implements auto-direction sensing using edge-triggered one-shot circuits that dynamically enable PMOS/NMOS drivers during rising/falling transitions-eliminating need for external DIR control. Its I/O cells feature weak static drive (70 Ω typical at 1.2–1.8 V VCCO) to allow bus contention resolution while accelerating transitions via short-duration boost pulses.
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, blocking damaging backflow current during partial power-down. Inputs tolerate up to 5.5 V regardless of VCC(A) level, and OE is referenced solely to VCC(A), enabling robust enable control in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range A | VCC(A): 1.2 V to 3.6 V - powers A-port I/Os and OE; sets logic thresholds for A-side signals |
| Supply Range B | VCC(B): 1.65 V to 5.5 V - powers B-port I/Os; defines output swing and input tolerance on B side |
| Data Rate | Up to 100 Mbps (at VCC(A)=3.3 V, VCC(B)=5.0 V, –40 °C to +125 °C) - supports high-speed SPI, UART, and GPIO bridging |
| Propagation Delay | 0.8–12.9 ns (A↔B, depending on VCC pair and temp) - ensures sub-13 ns latency for real-time inter-domain signaling |
| IOFF Leakage | ±2 μA max (–40 °C to +125 °C) - prevents >2 μA backfeed current when one supply is off, protecting powered-down subsystems |
| ESD Protection | HBM: 2500 V (A port), 15 kV (B port); CDM: 1500 V - withstands handling and board-level ESD in industrial environments |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive, motor control, and industrial PLC applications |
Pinout & Package
NTB0102GT,115 uses SOT833-1: XSON8 package - plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 × 1.95 × 0.5 mm, wettable flank compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 (B2, B1) | B-side bidirectional data I/O | Referenced to VCC(B); accept inputs up to 5.5 V; drive outputs from VCC(B) rail |
| 2 | GND | Common ground reference for both supply domains and internal logic |
| 3 | VCC(A) | Supply for A-port I/Os and OE input; defines A-side logic thresholds and drive strength |
| 4, 5 (A2, A1) | A-side bidirectional data I/O | Referenced to VCC(A); operate down to 1.2 V; tolerate no overvoltage beyond VCC(A)+0.5 V |
| 6 | OE | Active-HIGH output enable; referenced to VCC(A); forces all I/Os into high-impedance state when LOW |
| 7 | VCC(B) | Supply for B-port I/Os; sets B-side output voltage range and input tolerance ceiling |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates external DIR signal and associated routing; detects data flow direction via edge-triggered one-shot logic on A/B ports |
| Asymmetric dual-supply operation | Independent VCC(A) (1.2–3.6 V) and VCC(B) (1.65–5.5 V) enable translation between 1.2 V MCU and 5 V peripheral without level-shifter ICs |
| IOFF partial power-down | Automatically disables outputs and blocks backflow current when either VCC(A) or VCC(B) = 0 V - critical for hot-swap and sleep-mode isolation |
| High-B port ESD rating | 15 kV HBM on B port - protects against electrostatic discharge in exposed I/O paths (e.g., USB, display, sensor interfaces) |
| Low dynamic power dissipation | CPD as low as 0.01 pF (B port, disabled) - reduces switching power in high-frequency GPIO translation applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0102DCUR | TI device; 2-bit; VCCA: 1.2–3.6 V, VCCB: 1.65–5.5 V; 12-pin VSSOP; higher ICC(B) (15 μA typ vs. 3.3 μA) | Same functional scope but larger footprint; lacks IOFF - requires external power sequencing for safe partial shutdown | Choose TXS0102DCUR only if VSSOP assembly infrastructure exists and IOFF is not required for system-level power management. |
| SN74AVC2T244RSWR | Texas Instruments; dual 2-bit buffer; VCC: 1.2–3.6 V; unidirectional with DIR pin; no auto-sensing; 10-pin UQFN | Requires external direction control logic and two separate enable pins; no B-side 5 V tolerance - limited to ≤3.6 V domains | Select SN74AVC2T244RSWR only when direction is statically known and both sides operate ≤3.6 V; avoid for true bidirectional 5 V interfacing. |
Compared with TXS0102DCUR and SN74AVC2T244RSWR, NTB0102GT,115 uniquely combines auto-direction sensing, IOFF-enabled partial power-down, 5 V-tolerant B inputs, and XSON8 space savings - making it optimal for thermally constrained, hot-pluggable, or automotive-grade bidirectional bridges where direction is dynamic and power sequencing is complex.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for NTB0102GT,115?
The NTB0102GT,115 requires VCC(A) ≤ VCC(B) during normal operation per datasheet Section 12.4. While VCC(A) may transiently exceed VCC(B) during power-up without damage, sustained operation above this limit risks undefined behavior and is not guaranteed. The absolute maximum ratings allow both supplies up to +6.5 V independently, but functional operation mandates VCC(A) ≤ VCC(B).
Does NTB0102GT,115 support I²C or 1-Wire bus protocols?
No - NTB0102GT,115 is not recommended for I²C or 1-Wire applications. Its weak static drive strength (designed for capacitive loads ≤70 pF) and lack of open-drain compatibility create risk of bus contention. Section 12.6 explicitly states that pull-up/pull-down resistors must exceed 50 kΩ, disqualifying standard I²C pull-ups (typically 2.2–10 kΩ). For I²C, NXP recommends the NTS0102-Q100 instead.
How does the auto-direction sensing work in NTB0102GT,115 without a DIR pin?
NTB0102GT,115 uses internal edge-detection one-shot circuits on each I/O pair (A1/B1 and A2/B2). When a rising or falling edge is detected on either side, the corresponding PMOS or NMOS driver is briefly activated to accelerate the transition - effectively "sensing" direction by responding to signal activity. This eliminates the need for an external DIR control signal while maintaining full bidirectional transparency.
What is the disable time (tdis) for NTB0102GT,115 when OE is pulled LOW?
For NTB0102GT,115, the disable time tdis is specified as ≤220 ns (max) across –40 °C to +125 °C when OE transitions from HIGH to LOW, measured with no external load. This value applies to both A and B ports and is consistent across all supported VCC(A)/VCC(B) combinations per Table 12 of the datasheet.
Can NTB0102GT,115 translate between 1.2 V and 5.0 V logic domains reliably?
Yes - NTB0102GT,115 is fully specified for 1.2 V (VCC(A)) to 5.0 V (VCC(B)) translation. Its B-port inputs tolerate up to 5.5 V regardless of VCC(A) level, and its A-port outputs swing to VCC(A) levels while B-port outputs swing to VCC(B) levels. Static and dynamic parameters (e.g., VOL/VOH, propagation delay, data rate) are validated across this full range in the datasheet.
