Product Overview
TXB0104PWR is a Texas Instruments 4-bit bidirectional noninverting voltage-level translator for Signal_Chain interfaces. It uses automatic direction sensing, so no separate direction-control pin is specified for bidirectional voltage-level translation. The supply arrangement requires VCCA to be less than or equal to VCCB, with recommended operating ranges of 1.2 V to 3.6 V on the A port and 1.65 V to 5.5 V on the B port.
The device is supplied in a TSSOP (14), 5.00 mm x 4.40 mm package case identified for TXB0104PW. Output enable is referenced to VCCA, and driving OE low places all outputs in the high-impedance state. VCC isolation is provided: outputs are high impedance if either VCC input is at GND. Ioff support disables outputs to help prevent current backflow during partial power-down conditions.
Electrical limits include 5 uA maximum supply current, -40 °C to 85 °C operating free-air temperature, and input transition rise/fall-rate limits of 40 ns/V on A-port inputs and 40 ns/V or 30 ns/V on B-port inputs depending on VCCB range. The part is applicable to mixed-voltage digital interfaces that need four translated channels, tri-state behavior, and defined power-off handling.

Procurement Notes
When requesting a quote for TXB0104PWR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
What type of device is TXB0104PWR?
TXB0104PWR is a Texas Instruments 4-bit bidirectional noninverting voltage-level translator. It belongs to the Signal_Chain category and supports automatic direction sensing for bidirectional voltage-level translation.
What supply ranges does TXB0104PWR support?
The A-port recommended supply range is 1.2 V to 3.6 V, and the B-port recommended supply range is 1.65 V to 5.5 V. The required supply relationship is VCCA less than or equal to VCCB.
How does output enable behave on TXB0104PWR?
