The TXS0104EQPWRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade 4-bit bidirectional voltage-level translator designed for open-drain and push-pull applications requiring no direction-control signal. Encapsulated in the PW (TSSOP-14) package measuring 5mm x 6.4mm and shipped in tape and reel format, this auto-direction sensing level shifter supports VCCA from 1.65V to 3.6V and VCCB from 2.3V to 5.5V (with VCCA ≤ VCCB), enabling seamless translation between 1.8V, 2.5V, 3.3V, and 5V logic nodes. The device achieves maximum data rates of 24Mbps in push-pull mode and 2Mbps in open-drain mode, with no power-supply sequencing required since either rail can be ramped first.
Applications
The TXS0104EQPWRQ1 automotive translator is primarily deployed in automotive infotainment systems and advanced driver assistance systems (ADAS), where it isolates and level-translates signals between the main processor operating at low voltage and peripheral modules running at 3.3V or 5V. It is extensively used for I2C or 1-wire bus voltage-level translation in battery management, sensor interfaces, and body control modules. Typical deployments include bridging 1.8V microcontroller GPIOs to 3.3V CAN transceivers, translating 2.5V SPI buses to 5V legacy peripherals, and connecting mixed-voltage domains in ECUs, telematics units, and camera modules where AEC-Q100 compliance is mandatory.
Frequently Asked Questions
Q1: What is the difference between TXS0104E and TXB0104? The TXS0104E uses passive auto-direction sensing with internal 10kΩ pullup resistors suited for open-drain and push-pull applications, while the TXB0104 uses active drivers with direction control for higher-speed push-pull-only operation.
Q2: Can external pull-up resistors be added to TXS0104EQPWRQ1 outputs? Yes, external pullups can reduce total RC delay, but should be sized considering the 10kΩ internal pullup, and pulldown resistors must be limited to 50kΩ or greater to avoid degraded VOH levels.
Alternative Models
● TXS0104EQPWR: The commercial-grade (non-automotive) version with identical 4-bit bidirectional translation specifications in TSSOP-14, suitable for consumer and industrial applications not requiring AEC-Q100.
● TXS0104ERUTQ1: The automotive-qualified variant in ultra-compact 12-pin UQFN (RUT) package measuring 2mm x 1.7mm, for space-constrained automotive designs.
● TXB0104QDBVRQ1: The TXB-series active bidirectional translator with 4 channels and 20Mbps push-pull capability, suitable when active drivers and direction control are preferred over passive auto-sensing.
● TXS0108EQPWRQ1: The 8-channel automotive version of the same TXS series in 20-TSSOP, doubling channel count for buses requiring parallel translation of multiple data lines.
