Product details
Overview
NTB0101GS1XL from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing translating transceiver 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 6-pin X2SON6 package, 3-state output control via active-HIGH OE, IOFF partial power-down protection, and operates across −40 °C to +125 °C. It is used in mixed-voltage I/O interfacing such as 1.8 V microcontroller to 3.3 V sensor communication.
For engineers reviewing the NTB0101GS1XL datasheet, NTB0101GS1XL pinout, NTB0101GS1XL application, or NTB0101GS1XL equivalent, key selection criteria include auto-direction sensing capability, dual-rail supply flexibility, IOFF-enabled safe power sequencing, ESD robustness (15 kV HBM on B port), and ultra-thin 1.0 × 1.0 × 0.32 mm X2SON6 footprint for space-constrained embedded designs.
Technical Context
The NTB0101GS1XL implements an edge-detecting one-shot architecture with weak-output drivers that allow external overdrive during direction reversal-no external direction control signal required. Its internal PMOS/NMOS acceleration circuits reduce transition times, delivering typical B-port rise/fall times of 1.4–4.7 ns depending on VCC(B).
IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, blocking damaging backflow current. Input clamping and ±1 µA max leakage at 125 °C ensure reliability in hot industrial environments, while propagation delay remains under 10 ns (A↔B) across full voltage/temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side logic and OE; must be ≤ VCC(B) during operation |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side I/O; supports legacy 5 V and modern low-voltage systems |
| Propagation Delay | 0.8–12.9 ns (A↔B) - enables >40 Mbps data rate at −40 °C to +85 °C, up to 100 Mbps at 3.3 V/25 °C |
| ESD Rating (B port) | HBM Class 3B >15,000 V - protects against handling discharge in high-voltage domain interfaces |
| IOFF Leakage | ±2 µA max at 125 °C - ensures safe isolation during partial power-down without external circuitry |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control applications |
| Package | X2SON6 (SOT1202-2), 1.0 × 1.0 × 0.32 mm - ultra-thin, leadless, PCB area <1 mm², suitable for wearable and portable devices |
Pinout & Package
X2SON6 plastic super-thin small outline package (SOT1202-2), no leads, 6 terminals, 1.0 × 1.0 × 0.32 mm body height, wettable flank option not specified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply for A-side logic and OE input | Reference for A port and OE; must be ≤ VCC(B); powers internal direction-sensing circuitry |
| GND | Common ground reference | Single ground connection shared by both sides; required for proper IOFF and ESD path integrity |
| A | Bidirectional data terminal (A-side) | I/O referenced to VCC(A); accepts inputs up to 5.5 V; drives 1.2–3.6 V logic levels |
| B | Bidirectional data terminal (B-side) | I/O referenced to VCC(B); accepts inputs up to 5.5 V; drives 1.65–5.5 V logic levels |
| OE | Active-HIGH output enable | Referenced to VCC(A); LOW forces A/B into high-impedance OFF-state; pull-down recommended for power-up safety |
| VCC(B) | Supply for B-side I/O drivers | Reference for B port; enables translation to 5 V systems; IOFF activates if driven to GND |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction control line; detects data edge transitions to autonomously configure A↔B path |
| Dual-rail supply independence | VCC(A) and VCC(B) can be powered/sequenced independently; no damage during VCC(A) ≥ VCC(B) at power-up |
| IOFF partial power-down | Prevents backflow current when either supply is off; meets JEDEC JESD78B Class II latch-up immunity (>100 mA) |
| Ultra-low static leakage | ≤±2 µA I/O leakage at 125 °C - maintains signal integrity in always-on subsystems without external biasing |
| High-speed B-port transitions | 1.4 ns typical B-port fall time at 5 V - supports clean timing margins in 50+ Mbps digital interfaces |

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 |
|---|---|---|---|
| TXS0101DRYR | Single-bit, auto-direction, 1.65–3.6 V VCCA / 2.3–5.5 V VCCB; 6-pin X2SON; no IOFF; lower ESD (8 kV HBM B port) | Lacks IOFF - unsuitable for partial power-down systems requiring backflow prevention | Select when cost sensitivity outweighs IOFF requirement and ambient temperature stays ≤85 °C |
| SN74AVC1T45DBVR | 1-bit, dual-supply, direction-controlled (DIR pin required); 1.2–3.6 V VCCA / 1.2–3.6 V VCCB; 6-pin SOT-23; includes IOFF | Requires external DIR signal - adds MCU GPIO overhead and routing complexity | Choose only when strict 1.2 V compatibility on both rails is mandatory and direction is predictable/static |
Compared with TXS0101DRYR and SN74AVC1T45DBVR, NTB0101GS1XL uniquely combines auto-direction sensing, full 1.2–5.5 V dual-rail support, IOFF, and 15 kV HBM B-port ESD - making it the only option qualified for hot-swappable, mixed-voltage industrial modules operating continuously at 125 °C.

FAQ
What is the maximum data rate supported by NTB0101GS1XL?
The NTB0101GS1XL supports up to 100 Mbps at 25 °C with VCC(A) = 3.3 V and VCC(B) = 5.0 V, and maintains ≥40 Mbps across −40 °C to +85 °C. This is enabled by sub-10 ns propagation delay and fast B-port transition times (as low as 1.4 ns), verified per Table 10 and Table 11 of the official NXP datasheet Rev. 7.
Does NTB0101GS1XL require external pull-up resistors on A or B ports?
No - NTB0101GS1XL does not require external pull-up resistors. Its internal weak-output drivers are designed for capacitive loads ≤70 pF. External pull-up/pull-down resistors must exceed 50 kΩ to avoid contention; use is discouraged for open-drain buses like I²C. The NTB0101GS1XL datasheet explicitly recommends NTS0101 for such protocols.
Can NTB0101GS1XL operate with VCC(A) = 1.2 V and VCC(B) = 5.0 V simultaneously?
Yes - NTB0101GS1XL is fully specified for VCC(A) = 1.2 V to 3.6 V and VCC(B) = 1.65 V to 5.5 V concurrently. At this combination, it delivers 1.2 V ↔ 5.0 V bidirectional translation with VOH ≥ 4.6 V (B port) and VOL ≤ 0.4 V, meeting TTL and CMOS interface thresholds per Table 9 static characteristics.
Is NTB0101GS1XL pin-compatible with other NTB0101 variants like NTB0101GM or NTB0101GN?
Yes - all NTB0101 variants share identical 6-pin XSON/X2SON functional pinout (VCC(A), GND, A, B, OE, VCC(B)), including NTB0101GS1XL (SOT1202-2), NTB0101GM (SOT886), and NTB0101GN (SOT1115). Mechanical dimensions differ, but PCB layout can reuse same pad stack with minor land pattern adjustments for solder fillet control.
What is the purpose of the IOFF feature in NTB0101GS1XL?
The IOFF feature in NTB0101GS1XL disables outputs and blocks current backflow when either VCC(A) or VCC(B) is at GND, preventing damage during partial power-down. Measured IOFF leakage is ≤±10 µA at 125 °C (Table 9), satisfying JEDEC JESD78B Class II latch-up immunity and enabling safe integration into multi-rail power systems.
