Product details
Overview
NTS0104GU12,115 from NXP Semiconductors is a 4-bit dual-supply auto-sensing bidirectional voltage-level translating transceiver in XQFN12 package. It enables seamless interfacing between 1.8 V/2.5 V/3.3 V and 5.0 V domains (VCC(A): 1.65–3.6 V; VCC(B): 2.3–5.5 V), supports 50 Mbps push-pull data rate, features IOFF partial power-down protection, and operates across −40 °C to +125 °C for I²C/SMBus and GPIO voltage translation.
For engineers reviewing the NTS0104GU12,115 datasheet, NTS0104GU12,115 pinout, NTS0104GU12,115 application, or NTS0104GU12,115 equivalent, this page delivers verified electrical parameters, thermal specifications, real-world interface constraints, and validated alternative options - all aligned with NXP's Rev. 3 product data sheet dated 3 January 2012.
Technical Context
The NTS0104GU12,115 implements a switch-type architecture using N-channel pass-gate transistors with gate bias referenced to the lower-voltage supply side. Its auto-direction sensing eliminates external direction control signals by detecting edge transitions on either port.
Each I/O channel integrates an output edge-rate accelerator (one-shot circuit) that activates at ~VCCI/2 and sustains for ~50 ns, reducing rising-edge transition time via internal PMOS bypass of 10 kΩ pull-ups. Internal 10 kΩ pull-up resistors are present on both A and B ports, disabled when OE = LOW.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC(A) Range | 1.65 V to 3.6 V - powers A-side logic and defines A-port voltage reference; must be ≤ VCC(B) during operation. |
| VCC(B) Range | 2.3 V to 5.5 V - powers B-side logic and defines B-port voltage reference; supports 5 V legacy interfaces. |
| Max Data Rate | 50 Mbps - achievable with push-pull drivers and ≤50 Ω source impedance; limited by one-shot pulse duration under capacitive load. |
| IOFF Leakage | ±1 µA max (−40 °C to +125 °C) - prevents damaging backflow current when either supply is powered down. |
| Propagation Delay | A↔B: 2.4–7.3 ns - varies with VCC(A)/VCC(B) combination and temperature; worst-case at 1.8 V/5.0 V and +125 °C. |
| ESD Robustness | B port: >8 kV HBM, >8 kV IEC61000-4-2 contact - enables direct connection to exposed I²C buses without external protection. |
| Operating Temp | −40 °C to +125 °C - qualified for automotive under-hood and industrial control applications requiring extended thermal margin. |
Pinout & Package
XQFN12 package (SOT1174-1), 1.70 × 2.0 × 0.50 mm body, 12-terminal no-lead construction with exposed thermal pad (non-soldered, floating or GND-connected per design).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Common 0 V return for both supply domains; required for proper IOFF and ESD path integrity. |
| OE | Output enable input | Active-HIGH signal referenced to VCC(A); LOW forces all I/Os into high-impedance OFF-state with tdis ≤ 45 ns (+125 °C). |
| VCC(B) | Supply voltage B | Power rail for B-side I/Os (B1–B4); sets VOH/VOL thresholds and internal pull-up target for B port. |
| B1–B4 | B-side I/O terminals | Open-drain compatible; each has internal 10 kΩ pull-up to VCC(B); accept inputs up to 5.5 V independent of VCC(B). |
| A1–A4 | A-side I/O terminals | Referenced to VCC(A); each has internal 10 kΩ pull-up to VCC(A); tolerate overvoltage up to 5.5 V on input. |
| VCC(A) | Supply voltage A | Power rail for A-side I/Os and OE input; determines VIH/VIL thresholds and gate bias for pass transistor T3. |
Key Features
| Feature | Design Value |
|---|---|
| Auto-direction sensing | Eliminates need for external DIR control line; detects data flow direction dynamically via edge detection on either port. |
| IOFF partial power-down | Disables outputs and blocks back-current when either VCC(A) or VCC(B) = 0 V - critical for hot-swap and multi-rail systems. |
| Integrated 10 kΩ pull-ups | Reduces external component count for I²C/SMBus; pull-ups disabled automatically when OE = LOW. |
| 5.5 V-tolerant inputs | A and B ports accept up to 5.5 V regardless of respective supply voltage - simplifies mixed-voltage debugging and test access. |
| One-shot edge acceleration | Improves rising-edge speed by temporarily enabling low-RDS(on) PMOS drivers; reduces tTLH by up to 40% vs passive pull-up. |

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 | TI device with identical 4-bit, dual-supply, auto-direction architecture; VCC(A): 1.2–3.6 V, VCC(B): 1.65–5.5 V; 60 Mbps rated. | Supports lower VCC(A) down to 1.2 V - suitable for ultra-low-voltage MCUs; lacks NXP's 8 kV IEC61000-4-2 B-port rating. | Select TXS0104E when interfacing sub-1.65 V logic or requiring marginally higher speed; verify ESD protection requirements match system environment. |
| PCA9306 | NXP device with 2-bit capacity, no OE pin, fixed 1.2–3.3 V / 1.8–5.5 V range; 400 kHz I²C-optimized, no push-pull support. | Limited to I²C-only use cases; no enable control or 50 Mbps capability; smaller footprint but lower flexibility. | Choose PCA9306 only for cost-sensitive, dedicated I²C bridges where 2-channel count and absence of OE are acceptable trade-offs. |
Compared with TXS0104E and PCA9306, the NTS0104GU12,115 provides broader VCC(A) compatibility than PCA9306 and superior ESD robustness for B-port connections versus TXS0104E - making it optimal for industrial I²C/SMBus links requiring reliability across wide temperature and voltage margins.

FAQ
What is the maximum allowable voltage difference between VCC(A) and VCC(B) for reliable operation of the NTS0104GU12,115?
The NTS0104GU12,115 requires VCC(A) ≤ VCC(B) during active operation per datasheet Section 10 (Recommended Operating Conditions). While absolute maximum ratings allow both supplies up to +6.5 V, sustained operation with VCC(A) > VCC(B) risks pass-transistor gate oxide stress and degraded IOFF performance. The device tolerates transient overshoot but must settle within the 1.65–3.6 V / 2.3–5.5 V ranges with VCC(A) not exceeding VCC(B).
Does the NTS0104GU12,115 support true push-pull driving on both A and B ports?
The NTS0104GU12,115 supports push-pull drivers on both A and B ports, achieving 50 Mbps data rates as specified in Table 10. However, its internal architecture relies on open-drain-compatible pass-gate switching - so external push-pull sources must drive into the device's input capacitance (4–7 pF per port) and respect VOL/VOH limits defined relative to their respective VCC rails. The datasheet confirms push-pull operation is valid but notes NTB0104 may be preferred for heavy push-pull loads.
How does the IOFF circuitry in the NTS0104GU12,115 protect against back-current during partial power-down?
The IOFF circuitry in the NTS0104GU12,115 disables output buffers and isolates conduction paths when either VCC(A) or VCC(B) drops to GND. This prevents reverse current flow through the pass-gate transistor (T3) or internal pull-ups, limiting leakage to ±1 µA across −40 °C to +125 °C. The protection activates automatically - no OE assertion required - making it ideal for systems with independent power domain sequencing.
Can the NTS0104GU12,115 be used without external pull-up resistors in I²C applications?
Yes - the NTS0104GU12,115 integrates 10 kΩ pull-up resistors on both A and B ports to their respective VCC rails, satisfying standard-mode (100 kHz) and fast-mode (400 kHz) I²C bus requirements when combined with typical bus capacitance (<400 pF). External pull-ups are unnecessary unless faster rise times, lower VOL, or stronger drive strength are needed - in which case parallel external resistors must be sized to avoid violating VOL specs.
What is the function of the exposed thermal pad on the XQFN12 package of the NTS0104GU12,115?
The exposed thermal pad on the NTS0104GU12,115's XQFN12 package (SOT1174-1) is electrically connected to the die substrate via conductive die attach material. Per datasheet Section 7.1, it has no mandatory electrical or mechanical soldering requirement. If soldered, the pad must remain floating or be connected to GND - never to VCC(A) or VCC(B) - to avoid compromising internal bias networks or creating unintended current paths.
