Product details
Overview
NTB0101GW,125 from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage level translator IC enabling bidirectional translation between 1.2 V–3.6 V (VCC(A)) and 1.65 V–5.5 V (VCC(B)) domains. It features 3-state outputs controlled by an active-HIGH OE input referenced to VCC(A), IOFF circuitry for partial power-down protection, and operation across −40 °C to +125 °C. It is used in mixed-voltage I/O interfacing between microcontrollers and peripherals such as sensors or memory.
For engineers reviewing the NTB0101GW,125 datasheet, NTB0101GW,125 pinout, NTB0101GW,125 application, or NTB0101GW,125 equivalent, key selection criteria include its auto-direction sensing capability, asymmetric supply range compatibility, IOFF-enabled power-down behavior, and SC-88 (SOT363) package suitability for space-constrained industrial and automotive control modules.
Technical Context
The NTB0101GW,125 implements a weak-output, edge-accelerated transceiver architecture with one-shot circuits that transiently activate PMOS/NMOS drivers during signal transitions-reducing propagation delay without requiring external direction control. Its dual-supply I/O cells isolate A-side (VCC(A)-referenced) and B-side (VCC(B)-referenced) logic domains while maintaining bidirectional data flow.
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 (15 kV HBM on B port, 2.5 kV on A port) are integrated, and the device complies with JESD78B Class II latch-up immunity (>100 mA).
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; must be ≤ VCC(B) in active operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-port logic; supports interface to 1.8 V, 2.5 V, 3.3 V, and 5.0 V systems |
| 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 | ±10 µA max at −40 °C to +125 °C - ensures safe isolation during power-down of either supply rail |
| ESD Protection (B port) | HBM Class 3B >15,000 V - protects high-voltage side against handling and system-level ESD events |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive and industrial motor control environments |
| Input Capacitance (B port) | 7.5 pF typical - low loading supports high-speed signal integrity on 5 V buses with minimal timing skew |
Pinout & Package
NTB0101GW,125 is housed in a plastic surface-mounted SC-88 package (SOT363), measuring 2.1 mm × 2.0 mm × 1.0 mm with 6 leads and gull-wing terminations. Pin 1 indicator is located on the lower left corner below the marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - VCC(A) | A-side supply rail | Reference for A port and OE input; must be ≤ VCC(B); powers internal level-shifting logic |
| 2 - GND | Common ground reference | Shared return path for both supply domains; required for proper IOFF and ESD clamp operation |
| 3 - A | Bidirectional I/O (A domain) | Referenced to VCC(A); auto-senses direction; accepts inputs up to 5.5 V with clamping |
| 4 - B | Bidirectional I/O (B domain) | Referenced to VCC(B); higher-voltage side; supports 5.0 V logic interfaces |
| 5 - OE | Output enable (active HIGH) | Referenced to VCC(A); drives both ports into high-impedance state when LOW; pull-down recommended for power-up safety |
| 6 - VCC(B) | B-side supply rail | Reference for B port; enables translation to legacy 5 V subsystems and wide-VDD applications |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals; reduces PCB routing complexity and MCU GPIO count |
| Asymmetric dual-supply operation | Enables direct interface between ultra-low-voltage cores (1.2 V) and standard I/O rails (3.3 V/5.0 V) without external biasing |
| IOFF partial power-down | Prevents damaging back-current when either VCC(A) or VCC(B) is unpowered - critical for hot-swap and modular power architectures |
| High-BWM ESD protection (B port) | 15 kV HBM rating allows direct connection to exposed connectors or cables in industrial fieldbus nodes |
| Low dynamic power dissipation | CPD as low as 0.01 pF in 3-state mode minimizes switching current in battery-powered sensor hubs |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCUR | Single-channel auto-direction translator with 1.65 V–5.5 V VCCA/VCCB range; no IOFF; 1.8 V min VCCA | Lacks partial power-down protection; not rated for −40 °C to +125 °C; suitable only for commercial-temperature consumer designs | Select when IOFF is unnecessary and ambient temperature stays ≤ +85 °C; verify OE logic compatibility (active LOW vs NTB0101GW,125's active HIGH) |
| SN74AVC1T45DBVR | Direction-controlled (DIR pin required); 1.2 V–3.6 V I/O; no B-port >3.6 V support; no IOFF | Requires additional MCU GPIO for DIR control; cannot translate to 5.0 V; unsuitable for hot-swap scenarios | Choose only if board has spare GPIO and system operates exclusively within 1.2 V–3.3 V domains; avoid for 5 V interface or power-sequencing-critical use cases |
Compared with TXS0101DCUR and SN74AVC1T45DBVR, NTB0101GW,125 uniquely combines auto-direction sensing, 5.0 V B-port support, IOFF-enabled partial power-down, and extended temperature qualification - making it the sole option among the three for robust, high-voltage, hot-swap-capable industrial and automotive level translation.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for NTB0101GW,125?
The NTB0101GW,125 requires VCC(A) ≤ VCC(B) during normal operation per datasheet Section 12.4. While absolute maximum ratings allow both supplies up to +6.5 V individually, sustained operation with VCC(A) > VCC(B) risks undefined behavior and is explicitly prohibited. During power-up, however, either supply may ramp first without damage.
Does NTB0101GW,125 support 5.0 V logic on both A and B ports?
No. The A port of NTB0101GW,125 is referenced to VCC(A) and supports inputs up to 5.5 V regardless of VCC(A) level (per Section 1 General description), but its output swing is limited to VCC(A). Only the B port, referenced to VCC(B), delivers full 5.0 V logic-compatible outputs when VCC(B) = 5.0 V.
Can NTB0101GW,125 be used in I²C or 1-Wire bus applications?
No. NTB0101GW,125 is not recommended for open-drain buses like I²C or 1-Wire (Section 12.6). Its weak-output architecture and minimum 50 kΩ pull-up requirement conflict with standard bus termination. For such protocols, NXP recommends the NTS0101 level translator instead.
What is the disable time (tdis) for NTB0101GW,125 when OE goes LOW?
For NTB0101GW,125, the disable time tdis is specified as 1.0–12.5 ns (OE to A) and 1.0–14.6 ns (OE to B) over −40 °C to +125 °C, depending on VCC(A)/VCC(B) combination (Table 12). These values reflect delay from OE transition to actual high-impedance state at the output pins under no external load.
Is NTB0101GW,125 still in active production or subject to obsolescence?
NTB0101GW,125 was discontinued with Last Time Buy on 24 April 2018 and Last Time Ship on 24 July 2018 (Table 1 ordering info). However, Aetrix Electronics maintains legacy inventory and offers lifecycle availability coordination, including traceable sourcing and BOM continuity management for ongoing production programs.
