Product details
Overview
NTB0104GU12,115 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XQFN12 package (1.70 × 2.0 × 0.50 mm), supporting VCC(A) = 1.2–3.6 V and VCC(B) = 1.65–5.5 V. It enables seamless interfacing between 1.2 V/1.5 V/1.8 V/2.5 V/3.3 V and 5.0 V domains without external direction control, with 3-state output enable (OE referenced to VCC(A)) and IOFF partial power-down protection.
For engineers reviewing the NTB0104GU12,115 datasheet, NTB0104GU12,115 pinout, NTB0104GU12,115 application, or NTB0104GU12,115 equivalent, this device is selected for low-power, space-constrained voltage translation in industrial I/O, portable MCU peripherals, and automotive body electronics where supply asymmetry and automatic direction sensing are critical.
Technical Context
The NTB0104GU12,115 implements edge-detecting one-shot circuitry on both A and B ports to autonomously enable PMOS/NMOS drivers during signal transitions-accelerating rise/fall times without requiring external direction signals. Its weak-output architecture allows bus contention resolution: outputs maintain defined logic levels statically but yield to stronger external drivers when reverse data flow begins.
IOFF circuitry actively disables outputs and blocks backflow current when either VCC(A) or VCC(B) is at GND, enabling safe partial power-down in mixed-voltage systems. Input tolerance up to 5.5 V on all pins-including A-side inputs-ensures robustness against overvoltage during hot-plug or fault conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.2 V to 3.6 V - supports direct connection to modern ultra-low-voltage MCUs and FPGAs (e.g., 1.2 V core, 1.5 V I/O). |
| VCC(B) Range | 1.65 V to 5.5 V - enables translation to legacy 3.3 V/5.0 V peripherals, sensors, and displays without level-shifter cascading. |
| Propagation Delay (A→B) | 0.9 ns (min) to 12.9 ns (max) at -40 °C to +85 °C - ensures sub-10 ns timing margin for 80 Mbps data rates in high-speed GPIO links. |
| IOFF Leakage | ±2 μA max at -40 °C to +125 °C - guarantees <100 nW standby power per channel during system sleep modes. |
| ESD Robustness (B port) | HBM Class 3B >15 kV - protects against ESD events in exposed I/O paths such as USB-C sideband use or automotive LIN interfaces. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive, industrial motor drives, and outdoor IoT edge nodes. |
| Package | XQFN12 (SOT1174-1), 1.70 × 2.0 × 0.50 mm - enables high-density routing on compact PCBs with 0.4 mm pitch and thermal-enhanced bottom paddle. |
Pinout & Package
XQFN12 package (SOT1174-1) with 12 terminals, 0.4 mm pitch, and exposed thermal pad. Pin 1 index located at top-left corner (A1 position). Bottom paddle is electrically connected to GND and must be soldered for thermal performance and EMI reduction.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Reference ground for both supply domains; connects to thermal pad for heat dissipation and noise suppression. |
| 2–5 | A1–A4 | 4-bit bidirectional I/O port referenced to VCC(A); accepts 0–5.5 V inputs regardless of VCC(A) level. |
| 6–9 | B1–B4 | 4-bit bidirectional I/O port referenced to VCC(B); tolerant of 0–5.5 V signals independent of VCC(B) setting. |
| 10 | VCC(B) | Supply for B-side logic and output drivers; sets VOH/VOL thresholds and output impedance (40–70 Ω). |
| 11 | VCC(A) | Supply for A-side logic, OE input, and internal direction-sensing circuitry; defines input threshold (VIH/VIL = 0.65/0.35×VCCI). |
| 12 | OE | Active-HIGH output enable referenced to VCC(A); LOW forces all A/B pins into high-impedance state with IOFF protection. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external direction-control signals or GPIOs, reducing MCU pin count and firmware complexity in bidirectional buses like I²C or SMBus stubs. |
| Wide dual-supply range | Independent VCC(A) and VCC(B) rails allow simultaneous interface between 1.2 V FPGA I/O banks and 5.0 V industrial actuators without intermediate regulators. |
| IOFF partial power-down | Prevents damaging back-current when one supply is powered off-critical for hot-swap modules and battery-backed subsystems. |
| 5.5 V-tolerant inputs | All pins accept up to 5.5 V regardless of VCC level, enabling direct connection to 5 V legacy peripherals without external clamping diodes. |
| High ESD immunity (B port) | 15 kV HBM rating on B-side pins ensures reliability in handheld test equipment and automotive infotainment touch interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104E | 4-bit auto-direction translator in X2SON10 (1.5 × 2.0 × 0.5 mm); VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; no IOFF; lower ESD (8 kV HBM B-port). | Lacks IOFF protection and has reduced thermal performance due to smaller package; unsuitable for partial-power-down systems. | Select TXS0104E only for cost-sensitive consumer applications where full power cycling is guaranteed and ESD exposure is minimal. |
| SN74AVC4T245 | 4-bit dual-supply translator in XQFN16 (2.5 × 2.5 × 0.5 mm); requires external direction control (DIR pin); VCC(A)/VCC(B): 1.2–3.6 V; no auto-sensing. | Requires dedicated MCU GPIO for direction control, increasing firmware complexity and pin utilization; lacks automatic bus arbitration. | Choose SN74AVC4T245 when deterministic direction control is preferred (e.g., SPI clocked interfaces) and board space permits larger 16-pin package. |
Compared with TXS0104E and SN74AVC4T245, the NTB0104GU12,115 uniquely combines auto-direction sensing, IOFF-enabled partial power-down, and industry-leading 15 kV B-port ESD in the smallest XQFN footprint-making it optimal for thermally constrained, safety-critical, and energy-efficient designs.

FAQ
What is the maximum data rate supported by the NTB0104GU12,115?
The NTB0104GU12,115 supports up to 100 Mbps under optimal conditions (VCC(A) = 3.3 V, VCC(B) = 5.0 V, Tamb = 25 °C), with guaranteed 40 Mbps operation across the full -40 °C to +125 °C range. Real-world throughput depends on load capacitance and signal integrity; for 15 pF loads, the device maintains <13 ns propagation delay enabling reliable 80 Mbps I²C or GPIO expansion links.
Does the NTB0104GU12,115 require external pull-up resistors on the A or B ports?
No-external pull-ups are not required for basic operation of the NTB0104GU12,115. The device's internal weak-output drivers maintain defined logic levels during idle states. However, pull-up resistors may be added on the B port for open-drain compatibility (e.g., I²C) or to strengthen static drive strength beyond the native 70 Ω typical output impedance.
Can VCC(A) exceed VCC(B) in the NTB0104GU12,115?
No-per datasheet Table 6 footnote [2], VCC(A) must be ≤ VCC(B) for correct operation of the NTB0104GU12,115. Violating this condition risks undefined direction sensing and potential output contention. For example, VCC(A) = 3.3 V is only valid when VCC(B) ≥ 3.3 V (e.g., 3.3 V or 5.0 V), not 2.5 V or 1.8 V.
How does the IOFF feature protect the NTB0104GU12,115 during partial power-down?
When either VCC(A) or VCC(B) drops to GND, the NTB0104GU12,115's IOFF circuitry disables all output drivers and limits leakage current to ±2 μA max, preventing destructive back-current flow through powered-down sections. This allows safe hot-swap of modular subsystems-such as removing a 5 V sensor board while the 1.8 V host MCU remains active-without latch-up or damage.
Is the NTB0104GU12,115 pin-compatible with other variants in the NTB0104 family?
No-the NTB0104GU12,115 uses the XQFN12 (SOT1174-1) package with 12 pins, while NTB0104BQ uses DHVQFN14 (14 pins) and NTB0104UK uses WLCSP12 (12-ball). Although functional equivalence exists, pin mappings differ: OE is on pin 12 in XQFN12 but pin 8 in DHVQFN14, and GND location varies. PCB redesign is required for substitution.
