Product Overview
TXS0102_Level-Shifter is a Texas Instruments Interface component for 2-bit bidirectional non-inverting voltage-level translation. The device uses automatic bidirectional translation, so direction control is not required. It is specified for push-pull data rates up to 24 Mbps and open-drain data rates up to 2 Mbps.
The recommended supply ranges are 1.65 V to 3.6 V on the A port and 2.3 V to 5.5 V on the B port, with VCCA less than or equal to VCCB. If either VCC input is at GND, both ports are placed in a high-impedance state, and no power-supply sequencing is required because either VCCA or VCCB may ramp first.
The output enable input is active high and referenced to VCCA; driving OE low places all I/Os in high impedance. Package options cover DCT SSOP-8, DCU VSSOP-8, DQE X2SON-8, DQM SON-8, YZP DSBGA-8, and DTT DSBGA-8 formats for compact interface assemblies.

Procurement Notes
When requesting a quote for TXS0102_Level-Shifter, 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 TXS0102_Level-Shifter?
TXS0102_Level-Shifter is a Texas Instruments 2-bit bidirectional voltage-level translator in the Interface category. It provides non-inverting automatic bidirectional translation and does not require a separate direction-control signal.
What supply ranges does TXS0102_Level-Shifter support?
The recommended A-port supply range is 1.65 V to 3.6 V, and the recommended B-port supply range is 2.3 V to 5.5 V. The specified operating condition requires VCCA to be less than or equal to VCCB.
What happens when OE is driven low?
The output enable input is active high and referenced to VCCA. When OE is low, all I/O pins are placed in a high-impedance state, supporting tri-state operation under the specified OE = GND condition.
What data rates are specified for this translator?
The device specifies a maximum data rate of 24 Mbps for push-pull applications and 2 Mbps for open-drain applications. These limits are tied to the application conditions stated in the extracted datasheet facts.
