Product details
Overview
TXS0104ENMNR from Texas Instruments is a 4-bit bidirectional voltage-level translator IC designed for open-drain and push-pull logic interfaces between mismatched voltage domains. It supports 1.65–3.6 V on the A port and 2.3–5.5 V on the B port (VCCA ≤ VCCB), delivers up to 24 Mbps in push-pull mode, requires no direction-control signal, and features OE-controlled 3-state outputs. It enables interoperability between 1.8-V/2.5-V/3.3-V microcontrollers and 5-V peripherals in space-constrained mobile applications.
For engineers reviewing the TXS0104ENMNR datasheet, TXS0104ENMNR pinout, TXS0104ENMNR application, or TXS0104ENMNR equivalent, this page provides verified electrical specifications, validated NanoFree™ nFBGA-12 package details, confirmed bidirectional translation behavior across voltage combinations, and real-world implementation guidance for handheld and embedded systems requiring robust level-shifting with zero sequencing constraints.
Technical Context
The TXS0104ENMNR uses passive MOSFET-based translation architecture without internal buffers or direction pins, enabling automatic bidirectional signal flow based on relative voltage levels at each port. Its OE input is referenced solely to VCCA, and all I/Os are rail-to-rail compatible with their respective supply rails.
It operates across –40°C to +85°C, supports simultaneous translation between 1.8-V and 5-V buses, and maintains sub-10 ns propagation delay (A-to-B, push-pull, VCCA = 3.3 V, VCCB = 5 V) while delivering ±1000-V CDM ESD protection on both ports and ±15-kV HBM on the B port.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| A-port voltage range | 1.65 V to 3.6 V - Enables direct interface with 1.8-V/2.5-V/3.3-V logic families without external biasing. |
| B-port voltage range | 2.3 V to 5.5 V - Supports legacy 5-V peripherals and newer 3.3-V/2.5-V systems with VCCA ≤ VCCB constraint. |
| Max data rate (push-pull) | 24 Mbps - Sufficient for high-speed I²C clock stretching, SPI control lines, and GPIO expansion in mobile SoC designs. |
| Max data rate (open-drain) | 2 Mbps - Matches standard I²C bus timing requirements up to 400 kHz with margin for rise-time compensation. |
| OE input reference | VCCA only - Simplifies power sequencing; OE remains functional even when VCCB is unpowered or ramped later. |
| ESD rating (B port, HBM) | ±15 kV - Provides robust system-level ESD immunity for exposed I/Os in handheld device interfaces. |
| Supply current (typical) | 14.4 µA total (ICCA + ICCB) - Enables always-on level shifting in battery-powered devices with negligible quiescent load. |
Pinout & Package
The TXS0104ENMNR is packaged in a 12-pin NanoFree™ nFBGA (NMN) measuring 2.0 mm × 2.5 mm with 0.5-mm pitch. This ultra-compact, leadless package eliminates bond wires and reduces parasitic inductance for high-speed signal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | I/O (A-side) | Bidirectional data lines referenced to VCCA; auto-translate signals from A to B or B to A depending on driving side. |
| B1–B4 | I/O (B-side) | Bidirectional data lines referenced to VCCB; tolerate up to VCCB + 0.5 V during active drive and –0.5 V in high-Z state. |
| VCCA | Power supply | Supplies A-port circuitry and OE logic; must be ≤ VCCB and within 1.65–3.6 V range. |
| VCCB | Power supply | Supplies B-port circuitry; independent of VCCA ramp sequence and supports wider 2.3–5.5 V range. |
| OE | Digital input | Active-high enable referenced to VCCA; drives all A/B I/Os into high-impedance when low (pull-down resistor required at power-up). |
| GND | Ground reference | Common return path for both supply domains; must be connected to system ground plane for noise control. |
Key Features
| Feature | Design Value |
|---|---|
| No direction-control signal | Eliminates need for MCU GPIO or timing-critical control logic, reducing firmware overhead and PCB routing complexity. |
| Independent power-supply rails | Allows asynchronous power-up of VCCA and VCCB - critical for hot-plug or partial-power-down system states. |
| High-impedance output control | OE input places all eight I/Os (A1–A4, B1–B4) simultaneously in 3-state mode, enabling bus sharing and conflict-free multi-master operation. |
| Integrated ESD protection | Meets IEC 61000-4-2 (±8-kV contact / ±10-kV air) on B port - reduces or eliminates need for external TVS diodes in portable designs. |
| NanoFree™ packaging | 0.5-mm pitch nFBGA eliminates solder leads and reduces board area by >50% vs. TSSOP, supporting ultra-thin smartphone and wearable layouts. |
Applications
| Smartphone Baseband Interface | Tablet Sensor Hub Integration |

IC Role / Device Role / Timing Role: Low-noise, high-ESD-tolerance translator placed directly at connector interface to suppress coupling into analog sections. Use Value: ±15-kV HBM protection on B port prevents ESD-induced lockup during field maintenance, while 2.0 mm × 2.5 mm footprint minimizes trace length near noisy display power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0104RGYR | Active-buffered architecture; requires direction control (DIR); higher drive strength (±24 mA); 14-pin VQFN. | Better for driving long traces or heavy capacitive loads; unsuitable where DIR signal is unavailable or layout lacks space for extra GPIO. | Select TXB0104RGYR only if push-pull drive strength >1 mA is required and DIR control is available. |
| SN74AVC4T245PW | Direction-controlled, dual-supply buffer with 3-state; supports 1.2–3.6 V on A port, 1.2–3.6 V on B port; no 5-V support. | Limited to sub-3.6-V systems; lacks B-port 5-V tolerance and ±15-kV HBM rating. | Choose SN74AVC4T245PW only for cost-sensitive, low-voltage-only designs where 5-V compatibility is unnecessary. |
Compared with TXB0104RGYR and SN74AVC4T245PW, the TXS0104ENMNR uniquely combines directionless operation, 5-V B-port tolerance, and industry-leading ESD robustness in a 2.0 mm × 2.5 mm footprint-making it optimal for compact, mixed-voltage, high-reliability mobile interfaces where GPIO count and board area are constrained.

FAQ
What is the maximum supported voltage difference between VCCA and VCCB for reliable operation of the TXS0104ENMNR?
The TXS0104ENMNR requires VCCA ≤ VCCB per datasheet specification, with absolute limits of 1.65–3.6 V on VCCA and 2.3–5.5 V on VCCB. The maximum allowed difference is therefore 5.5 V – 1.65 V = 3.85 V, but practical operation assumes VCCA is set to the lowest compatible logic voltage (e.g., 1.8 V) and VCCB to the highest (e.g., 5 V), resulting in a 3.2-V differential. Exceeding VCCA ≤ VCCB risks latch-up or undefined translation behavior in the TXS0104ENMNR.
Can the TXS0104ENMNR translate I²C signals reliably, and what design considerations apply?
Yes, the TXS0104ENMNR supports I²C translation in open-drain mode with verified 2 Mbps capability and built-in rise-time compensation. Key design considerations include using pull-up resistors only on the VCCB side (5 V), ensuring OE is held low during power-up via a VCCA-referenced pull-down resistor (≥10 kΩ), and avoiding bus capacitance exceeding 400 pF to maintain timing margins. The TXS0104ENMNR preserves I²C protocol integrity without external components.
Does the TXS0104ENMNR require external passive components for basic level-shifting functionality?
No, the TXS0104ENMNR operates as a standalone translator with no external passives required for core functionality. Only two decoupling capacitors (0.1 µF ceramic near VCCA and VCCB pins) and a pull-down resistor on OE (to GND, ≥10 kΩ) are recommended for stable power-up behavior. Unlike discrete FET solutions, the TXS0104ENMNR integrates all translation circuitry, eliminating external MOSFETs, resistors, or diodes.
How does the OE pin function in the TXS0104ENMNR, and what happens when it is left floating?
The OE pin on the TXS0104ENMNR is an active-high enable referenced exclusively to VCCA. When OE is high, bidirectional translation is active on all four A/B channels. When OE is low, all eight I/Os enter high-impedance state. If left floating, OE may float to an indeterminate voltage due to internal leakage, causing unpredictable output states - thus a VCCA-referenced pull-down resistor (e.g., 47 kΩ) is mandatory for robust power-up behavior in every TXS0104ENMNR design.
Is the TXS0104ENMNR pin-compatible with other members of the TXS0104E family, such as TXS0104EPW or TXS0104ERGY?
No, the TXS0104ENMNR (12-pin nFBGA) is not pin-compatible with TXS0104EPW (14-pin TSSOP) or TXS0104ERGY (14-pin VQFN). While electrically identical in function and specifications, the NMN package has different pin count, layout, and pad configuration - requiring unique PCB footprints and assembly processes. Migration between packages demands full layout revision and requalification; the TXS0104ENMNR is optimized for ultra-dense mobile applications where its 2.0 mm × 2.5 mm size delivers distinct mechanical advantage.
