Product Overview
TXB0106_Level-Shifter is a Texas Instruments Interface device implemented as a 6-bit noninverting bidirectional voltage translator. The translator uses auto-direction sensing, so direction control is handled by the device during bidirectional operation rather than by a separate direction pin.
The device supports mixed-voltage logic domains with VCCA from 1.2 V to 3.6 V and VCCB from 1.65 V to 5.5 V, with the recommended supply relationship of VCCA <= VCCB. Data input thresholds are defined relative to VCCI, while the OE input is referenced to VCCA. The recommended operating free-air temperature range is -40°C to 85°C.
Package availability spans PW TSSOP-16, RGY VQFN-16, RSV UQFN-16, BQB WQFN-16, and DYY SOT-16 footprints. Device behavior includes all outputs high-impedance when OE is low, all outputs high-impedance if either VCC input is at GND, and Ioff support to reduce current backflow during power-down conditions.

Procurement Notes
When requesting a quote for TXB0106_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 TXB0106_Level-Shifter?
TXB0106_Level-Shifter is a Texas Instruments 6-bit bidirectional voltage translator in the Interface category. It provides noninverting level shifting with auto-direction sensing for bidirectional translator operation.
What supply ranges does the TXB0106_Level-Shifter support?
The recommended VCCA range is 1.2 V to 3.6 V, and the recommended VCCB range is 1.65 V to 5.5 V. The specified supply relationship is VCCA <= VCCB during recommended operation.
What happens when OE is driven low?
When the OE input is low, all outputs are placed in a high-impedance state. The OE input thresholds are referenced to VCCA.
Does TXB0106_Level-Shifter support power-down protection?
Yes. The extracted datasheet facts state that Ioff is supported, with outputs disabled to prevent damaging current backflow during power down. All outputs are also high-impedance if either VCC input is at GND.
