Product Overview
TXB0102_Level-Shifter is a Texas Instruments Interface component described as a 2-bit bidirectional voltage-level translator. It provides noninverting bidirectional translation with auto direction sensing, supporting data movement between an A-port supply domain and a B-port supply domain without a separate direction-control input.
The recommended A-port supply voltage is 1.2 to 3.6 V, while the B-port supply voltage is 1.65 to 5.5 V. The specified supply relationship requires VCCA ≤ VCCB, and VCCA must not exceed 3.6 V. OE is referenced to VCCA, and all outputs are high-impedance when OE is low or when either VCC input is at GND.
The device supports Ioff circuitry for partial-power-down behavior, disabling outputs to inhibit current backflow. Package options are VSSOP-8 DCU at 2.30 mm × 2.00 mm and DSBGA-8 YZP at 0.90 mm × 1.80 mm. The operating free-air temperature range is -40 to 85 °C, with specified ESD, leakage, capacitance, transition-rate, and absolute-maximum ratings for design review.

Procurement Notes
When requesting a quote for TXB0102_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.
