Product Overview
TXS0108EPWR is an 8-bit non-inverting bidirectional level translator from Texas Instruments. It is intended for mixed-voltage digital signal translation between an A port supplied from 1.4 V to 3.6 V and a B port supplied from 1.65 V to 5.5 V. The recommended operating constraint is VCCA <= VCCB, and VCCA must not exceed 3.6 V.
The device does not require a direction-control signal for bidirectional translation. It supports maximum data rates of 110 Mbps in push-pull applications and 1.2 Mbps in open-drain applications. OE is referenced to VCCA; driving OE low places all outputs in a high-impedance state.
The TXS0108EPWR is supplied in a PW TSSOP-20 package measuring 6.50 mm x 6.40 mm, with a listed junction-to-ambient thermal resistance of 88.9°C/W. It operates from -40°C to 85°C and supports systems where either VCCA or VCCB can ramp first because no power-supply sequencing is required.

Procurement Notes
When requesting a quote for TXS0108EPWR, 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 TXS0108EPWR?
TXS0108EPWR is an 8-bit non-inverting bidirectional voltage translator from Texas Instruments. It belongs to the Signal_Chain category and is supplied in a PW TSSOP-20 package measuring 6.50 mm x 6.40 mm.
Does TXS0108EPWR require a direction-control signal?
No. The extracted datasheet facts state that no direction-control signal is needed for bidirectional translation. The device also provides an OE input, referenced to VCCA, that places all outputs in high impedance when driven low.
What supply ranges are recommended for TXS0108EPWR?
The recommended VCCA range is 1.4 V to 3.6 V, and the recommended VCCB range is 1.65 V to 5.5 V. The stated operating constraint is VCCA <= VCCB, and VCCA must not exceed 3.6 V.
What data rates does TXS0108EPWR support?
The device supports a maximum data rate of 110 Mbps in push-pull applications and 1.2 Mbps in open-drain applications. These limits depend on the stated application condition rather than a single universal data-rate rating.
What happens when OE is low on TXS0108EPWR?
When OE is low, all outputs are placed in the high-impedance state. The OE input is referenced to VCCA, with a low-level input range of 0 V to 0.35 x VCCA under the stated supply conditions.
