TXB0104QRUTRQ1 Visão geral
A voltage-level translator is a logic device that interfaces digital circuits operating at different supply voltages on the same PCB, such as a 1.8 V microcontroller talking to a 3.3 V or 5 V peripheral. translators sit within the broader logic IC hierarchy as members of the voltage-translation and signal-conditioning family used in mixed-voltage embedded systems.
Key features include AEC-Q100 Grade 1 qualification (-40C to +125C ambient), +/-15kV IEC ESD protection on the I/O pins, and automatic direction sensing that eliminates direction-control pins or firmware overhead. The TXB family push-pull architecture uses internal one-shot edge accelerators, giving rise and fall symmetry suited to push-pull CMOS outputs. The 12-UQFN package enables very dense layouts in space-constrained automotive modules.
Typical applications include automotive body electronics and lighting, infotainment and cluster SPI/I2C-adjacent push-pull signaling, sensor interface level shifting, and general-purpose MCU-to-peripheral level translation between 1.8 V, 2.5 V, 3.3 V, and 5 V domains. The wide 1.2 V low-side support makes it suitable for next-generation low-voltage processors.
Design note: this device is intended for push-pull CMOS signals; for open-drain buses such as I2C, choose the TXS family instead. Do not add external pull-up or pull-down resistors on TXB I/O lines, as they can defeat the automatic direction sensing.

Aplicações típicas
TXB0104QRUTRQ1 é adequado para 6 aplicaçãos: Automotive Body Electronics, Automotive Infotainment and Clusters, Sensor Interface Level Shifting, Mixed-Voltage MCU-to-Peripheral Translation, Industrial Control and PLC I/O, Automotive Lighting Modules.
Automotive Body Electronics
Body control modules mix 1.8 V MCU GPIO with 3.3 V and 5 V actuators, switches, and diagnostic lines. The TXB0104QRUTRQ1 fits because its AEC-Q100 Grade 1 rating (-40C to +125C) and +/-15kV IEC ESD protection withstand the harsh automotive electrical environment and harness transients. Its automatic direction sensing removes direction-control firmware from body function code. Four channels in a 1.7 mm x 2.0 mm UQFN consolidate multiple discrete transistor level-shift circuits, cutting BOM count while sustaining push-pull signal integrity up to 100 Mbps.
Recomendado
Automotive Infotainment and Clusters
Cluster and infotainment modules translate between low-voltage SoC GPIO (1.8 V) and 3.3 V or 5 V display, backlight, and peripheral logic. The TXB0104QRUTRQ1 supplies four bidirectional push-pull channels at up to 100 Mbps, fast enough for high-speed control and status signaling, with automatic direction sensing that simplifies A-port/B-port hookup. AEC-Q100 Grade 1 qualification covers the -40C to +125C cabin-ambient extremes, and the compact 12-UQFN fits dense PCBAs behind displays where layout area is at a premium.
Recomendado
Sensor Interface Level Shifting
Modern automotive and industrial sensors output push-pull digital signals at 1.8 V or 2.5 V while controllers and ADC front ends run at 3.3 V or 5 V. The TXB0104QRUTRQ1 bridges these domains with 1.2 V low-side support, the widest in its class among simple translators, and +/-15kV ESD robustness for wiring that leaves the module enclosure. Automatic direction sensing handles shared trigger/interrupt lines without a DIR pin. Four channels translate position, level, or status sensor outputs in one 1.7 mm x 2.0 mm UQFN package.
Recomendado
Mixed-Voltage MCU-to-Peripheral Translation
Embedded designs frequently pair a 1.8 V microcontroller with 3.3 V or 5 V peripherals such as EEPROM, displays, and motor drivers. The TXB0104QRUTRQ1 translates four push-pull GPIO, SPI-adjacent, or control signals bidirectionally at up to 100 Mbps with no direction pin, no enable pin, and no external pull resistors. The VCCA <= VCCB architecture directly supports 1.2 V to 3.6 V A-side logic against a 1.65 V to 5.5 V B-side rail. The 12-UQFN (RUT) footprint occupies minimal board area versus discrete BSS138-style circuits.
Recomendado
Industrial Control and PLC I/O
Industrial controllers translate 1.8 V DSP or FPGA bank I/O to 5 V field-side logic for motor drivers, relays, and diagnostics. The TXB0104QRUTRQ1 provides four push-pull bidirectional channels with 100 Mbps bandwidth, enough for fast PWM status and encoder-adjacent signaling, while its +125C rating suits control cabinets with limited airflow. Automatic direction sensing handles half-duplex lines without control GPIO overhead. Although automotive-qualified, its robust ESD and temperature specs give industrial designs extra margin at automotive-grade pricing.
Recomendado
Automotive Lighting Modules
Adaptive LED and matrix lighting modules mix low-voltage MCU logic with 3.3 V or 5 V driver ICs, fault-diagnosis lines, and fan or stepper control signals. The TXB0104QRUTRQ1 translates these push-pull lines bidirectionally at up to 100 Mbps with automatic direction sensing, and its +/-15kV IEC ESD rating helps survive connector-transient exposure near the lamp assembly. AEC-Q100 Grade 1 -40C to +125C coverage addresses underhood-adjacent temperature swings, while the 1.7 mm x 2.0 mm UQFN suits compact driver boards inside lamp housings.

Principais diferenciais
- Automotive AEC-Q100 Grade 1 qualification with +/-15kV ESD (vs TXB0104RUTR)

- 4-bit integration vs 2-bit alternatives (vs TXS0102-Q1)
Notas de projeto
Never place external pull-up or pull-down resistors on TXB0104 I/O pins. The automatic direction sensing uses weak internal pull-downs on the A port and pull-ups on the B port; external resistors can falsely trigger direction reversal or cause oscillation. For open-drain buses such as I2C that require pull-ups, select the TXS0104 instead.
Observe the VCCA <= VCCB constraint at all times, including during power sequencing. TI application guidance recommends powering VCCA before or simultaneously with VCCB; a floating or absent VCCA with VCCB applied can back-drive the A port. Use 0.1 uF ceramic decoupling capacitors on both VCCA and VCCB pins, placed within 2 mm of the pins given the 1.7x2.0 mm UQFN footprint.
The 12-UQFN (RUT) 1.7 mm x 2.0 mm land pattern is defined in TI datasheet Rev. D. Follow the datasheet recommended PCB layout with via-in-pad or short thermal reliefs on the center pads for manufacturability, and follow IPC/JEDEC moisture sensitivity handling for the reel packaging. Keep high-rate (100 Mbps) traces impedance-controlled and short, matching A-side and B-side trace lengths where signal integrity matters.
