Key Features
- 4-channel unidirectional translation between any voltage level from 1.2 V to 5.5 V without a direction-control pin
- Ultra-fast propagation delay under 4 ns enables use in high-speed data lines up to 100 Mbps
- Active pull-down on outputs prevents bus floating and reduces external component count
Applications
TXU0304PWR is ideal for mixed-voltage system boards where a microcontroller running at 1.8 V must communicate with legacy 3.3 V peripherals or 5 V sensors. The automatic direction sensing eliminates firmware overhead in static unidirectional signal paths such as SPI MISO, I2C SCL, or GPIO outputs. Its 14-pin TSSOP footprint integrates four independent channels, reducing the number of discrete components needed for level translation on dense PCBs.

Frequently Asked Questions
Which supply voltage range does TXU0304PWR support on each side of the translation barrier?
TXU0304PWR supports any supply voltage from 1.2 V to 5.5 V on both the A and B sides independently, allowing it to translate between common rails such as 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V in a single device.
How fast is TXU0304PWR, and can it handle SPI or SDIO data rates commonly seen in embedded systems?
The device achieves typical propagation delays below 4 ns and supports data rates up to 100 Mbps, which comfortably covers SPI at 20 MHz, SDIO at 50 MHz, and many UART and I2C protocols operating from 400 kHz to several MHz.
Does TXU0304PWR require a direction-control signal, and what advantage does that bring in hardware design?
No direction-control pin is required; the TXU0304PWR uses enable-high logic combined with automatic output management, which simplifies PCB routing by eliminating a dedicated direction GPIO line and reducing firmware complexity for purely unidirectional signal paths.
What is the package and channel count of TXU0304PWR, and how does it compare to larger translation ICs?
TXU0304PWR offers 4 independent translation channels in a 14-pin TSSOP (Small Outline Package) measuring approximately 5 mm × 4.4 mm; for applications needing only 4 channels this is more efficient than larger 8-channel packages that waste unused gates and add unnecessary board area.
At what load capacitance is TXU0304PWR specified, and how should designers handle heavier capacitive loads?
The device is rated at a typical load capacitance of 5 pF per channel; for lines with higher parasitic capacitance above 50 pF, designers should reduce the bus clock frequency proportionally or add series termination resistors of 22 Ω to 33 Ω to maintain signal integrity and meet setup/hold timing requirements.
