Product details
Overview
NTB0101GS1Z from NXP Semiconductors is a 1-bit dual-supply auto-direction-sensing voltage-level translating transceiver enabling bidirectional 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, IOFF partial power-down protection, ±1 µA OFF-state leakage, and supports 100 Mbps data rate at 3.3 V/5.0 V operation in industrial temperature range (−40 °C to +125 °C). It is used in mixed-voltage I/O interfacing between low-power microcontrollers and higher-voltage peripherals.
For engineers reviewing the NTB0101GS1Z datasheet, NTB0101GS1Z pinout, NTB0101GS1Z application, or NTB0101GS1Z 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-compact 1.0 × 1.0 × 0.32 mm X2SON6 footprint for space-constrained embedded designs.
Technical Context
The NTB0101GS1Z implements an edge-detecting one-shot architecture with weak output drivers (70 Ω at 1.2–1.8 V, 50 Ω at 1.8–3.3 V, 40 Ω at 3.3–5.0 V) that enable automatic direction control without external logic. Its IOFF circuitry actively disables outputs when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down.
It operates with OE referenced to VCC(A), A port referenced to VCC(A), and B port referenced to VCC(B); VCC(A) must be ≤ VCC(B) in active mode. Input voltage tolerance up to 5.5 V on both ports and latch-up immunity >100 mA per JESD78B Class II ensure robust system-level integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - powers A-side logic and defines A-port voltage reference; enables interface with 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V systems. |
| VCC(B) Range | 1.65 V to 5.5 V - powers B-side logic and defines B-port reference; supports 1.8 V/2.5 V/3.3 V/5.0 V domains including legacy interfaces. |
| Data Rate | Up to 100 Mbps - verified at VCC(A)=3.3 V/VCC(B)=5.0 V over −40 °C to +125 °C; enables high-speed serial bus bridging (e.g., UART, SPI). |
| Propagation Delay | A→B: 0.8–7.7 ns, B→A: 0.9–7.9 ns - low-latency bidirectional translation critical for real-time control loops and timing-sensitive protocols. |
| ESD Protection | HBM Class 3B >15 kV on B port, Class 2 >2.5 kV on A port - ensures reliability in handling-sensitive industrial and automotive assembly environments. |
| IOFF Leakage | ±1 µA max at VCC=0 V - guarantees zero-current path during power-down, eliminating risk of backfeeding into unpowered rails. |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and extended-temperature IoT edge nodes. |
Pinout & Package
NTB0101GS1Z uses the X2SON6 (SOT1202-2) package: plastic super-thin small outline, no leads, 6 terminals, 1.0 × 1.0 × 0.32 mm body. Pin 1 indicator is located on the lower left corner below the marking code "T1".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC(A) | Supply voltage A | Reference rail for A-port logic and OE input; must be ≤ VCC(B) in active mode. |
| GND | Ground (0 V) | Common return path for both supply domains; required for ESD clamp reference and signal integrity. |
| A | Data I/O (VCC(A)-referenced) | Bidirectional data terminal for low-voltage domain; accepts inputs up to 5.5 V regardless of VCC(A). |
| B | Data I/O (VCC(B)-referenced) | Bidirectional data terminal for high-voltage domain; tolerates 0–5.5 V inputs independent of VCC(B) level. |
| OE | Output enable (active HIGH, VCC(A)-referenced) | Global 3-state control; LOW forces high-impedance OFF-state on both A and B ports simultaneously. |
| VCC(B) | Supply voltage B | Reference rail for B-port logic; sets output voltage swing and drive strength for B-side signals. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals or GPIOs, reducing PCB routing complexity and firmware overhead in bidirectional buses. |
| IOFF partial power-down | Prevents damaging backflow current when either VCC(A) or VCC(B) is powered off - essential for hot-swap and modular power architectures. |
| Wide dual-supply range | Supports all common voltage combinations (1.2↔3.3 V, 1.8↔5.0 V, etc.) without external resistors or level-shifter ICs - simplifies BOM and design reuse. |
| Ultra-low static leakage | ±1 µA max OFF-state and power-off leakage - preserves battery life in always-on sensor nodes and enables reliable deep-sleep modes. |
| High ESD robustness | 15 kV HBM on B port meets IEC 61000-4-2 Level 4 requirements - reduces need for external TVS diodes in industrial fieldbus interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0101DCKR | Single-bit auto-direction translator with identical 1.2–3.6 V / 1.65–5.5 V supply ranges but larger SC-70-6 (SOT353) package (2.0 × 1.25 × 0.9 mm) and no IOFF. | Lacks IOFF protection - unsuitable for partial power-down scenarios where one rail may be inactive. | Select TXS0101DCKR only if board space allows larger footprint and system power sequencing guarantees both rails remain active. |
| SN74LVC1T45DBVR | Manual-direction 1-bit translator with 1.65–5.5 V single-supply operation, no auto-sensing, and higher 10 µA ICC typical supply current. | Requires external direction-control signal and cannot support true bidirectional bus arbitration without added logic. | Choose SN74LVC1T45DBVR only when deterministic direction control is preferred and additional GPIO is available for DIR pin management. |
Compared with TXS0101DCKR and SN74LVC1T45DBVR, NTB0101GS1Z uniquely combines auto-direction sensing, IOFF-enabled safe power-down, and the smallest industry-standard X2SON6 footprint - making it optimal for space-constrained, mixed-rail, and hot-swap-capable designs where reliability and minimal BOM are critical.

FAQ
What is the maximum data rate supported by NTB0101GS1Z?
The NTB0101GS1Z supports up to 100 Mbps data rate when operating at VCC(A) = 3.3 V and VCC(B) = 5.0 V over the full −40 °C to +125 °C temperature range. At lower supply voltages (e.g., 1.8 V/2.5 V), the guaranteed minimum data rate is 40 Mbps. This performance is validated per Table 11 and Table 12 in the official NXP datasheet Rev. 7.
Does NTB0101GS1Z require external direction-control signals?
No, NTB0101GS1Z does not require external direction-control signals. It uses internal edge-detecting one-shot circuits to automatically sense data flow direction on the A and B ports, enabling true bidirectional translation without GPIO overhead or timing-critical control logic. This behavior is intrinsic to the NTB0101GS1Z architecture as described in Section 12.2 of the datasheet.
Can NTB0101GS1Z operate with VCC(A) greater than VCC(B)?
No, NTB0101GS1Z requires VCC(A) ≤ VCC(B) during active operation per Section 8 and Section 12.4 of the datasheet. While VCC(A) ≥ VCC(B) during power-up is non-damaging and requires no special sequencing, sustained violation in active mode risks undefined output behavior and potential latch-up. The NTB0101GS1Z specification explicitly enforces this constraint for reliable translation.
What is the purpose of the IOFF feature in NTB0101GS1Z?
The IOFF feature in NTB0101GS1Z disables output drivers and blocks current flow when either VCC(A) or VCC(B) is at GND, preventing damaging backflow current during partial power-down. This protects downstream circuitry and ensures safe hot-plug operation - a critical requirement confirmed in Section 1 and Table 9 of the NTB0101GS1Z datasheet.
Is NTB0101GS1Z suitable for I²C or 1-Wire bus translation?
No, NTB0101GS1Z is not recommended for I²C or 1-Wire applications. Its weak output drivers (designed for capacitive loads ≤70 pF) and minimum 50 kΩ pull-up/pull-down requirement conflict with open-drain bus specifications. NXP explicitly recommends the NTS0101 for such use cases, as stated in Section 12.6 of the NTB0101GS1Z datasheet.
