Product Overview
The TXS0101 is a Texas Instruments 1-bit bidirectional level translator in the Signal_Chain category. It provides non-inverting translation with auto-direction sensing, so open-drain and push-pull signals can pass between the A and B sides without a separate direction-control input. The A pin is referenced to VCCA, while the B pin is referenced to VCCB.
Recommended operation uses VCCA from 1.65 V to 3.6 V and VCCB from 2.3 V to 5.5 V, with VCCA <= VCCB during normal operation. Push-pull operation supports up to 24 Mbps, while open-drain operation supports up to 2 Mbps. OE is referenced to VCCA, and pulling OE low places the outputs in a high-impedance state.
Power handling features include VCC isolation, no required supply sequencing, and Ioff support for partial-power-down operation. The device is offered in DBV, DCK, DRL, and DRY 6-pin packages with compact footprints for single-bit mixed-voltage signal paths.

Procurement Notes
When requesting a quote for TXS0101, 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 translator is the TXS0101?
The TXS0101 is a Texas Instruments 1-bit bidirectional level translator. It is non-inverting and uses auto-direction sensing for open-drain and push-pull applications, so no direction-control signal is required.
What supply ranges does TXS0101 support?
The A-port supply VCCA is specified from 1.65 V to 3.6 V, and the B-port supply VCCB is specified from 2.3 V to 5.5 V. Normal operation requires VCCA <= VCCB.
What happens when OE is driven low?
When OE is low, the TXS0101 outputs are placed in a high-impedance state. The OE input is referenced to VCCA, with a recommended low-level input range from 0 V to 0.35 x VCCA.
What are the maximum data rates for TXS0101?
The TXS0101 supports up to 24 Mbps in push-pull operation and up to 2 Mbps in open-drain operation. These limits depend on the operating mode stated in the datasheet facts.
