Product Overview
TXS0102DCUR is a Texas Instruments 2-bit bidirectional voltage-level translator for Signal_Chain use cases requiring logic-level translation between an A-port supply domain and a B-port supply domain. The A-port recommended operating supply range is 1.65 V to 3.6 V with VCCA ≤ VCCB, while the B-port recommended operating range is 2.3 V to 5.5 V. Bidirectional translation does not require a direction-control signal.

Procurement Notes
When requesting a quote for TXS0102DCUR, 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
