Auto-direction sensing means no direction-control GPIO is needed — the part detects the data flow and switches transparently, which simplifies firmware and saves a pin on the host controller. The output stage handles both open-drain (I2C-style) and push-pull signals, so it works with I2C, SMBus, UART, and general-purpose GPIO level shifting. ## Package and temperature — small footprint, industrial range Housed in an 8-XFDFN package with a supplier device package of 8-X2SON measuring 1.4 mm x 1.0 mm, this part is sized for dense PCB layouts — think wearable, IoT module, or multi-rail sensor hub. Surface-mount assembly is standard; the XFDFN package has no exposed thermal pad, so decoupling is straightforward — a 0.1 µF cap near each supply pin per the typical application circuit. No special baking is required beyond standard MSL handling (check the reel label for the specific level). ## Lifecycle — active, no end-of-life concern If your BOM calls for the same translator in a larger package (e.g., SOIC or TSSOP), the PCA9306 family includes those variants — check the NXP selector guide for the exact order code.","metaTitle":"PCA9306DQER Voltage Level Translator, 1.2V–5.5V","metaDescription":"NXP PCA9306DQER voltage level translator, 1.2V–3.3V VCCA / 1.8V–5.5V VCCB, bidirectional, auto-direction sensing, -40°C to 85°C, 8-XFDFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Auto-Direction Sensing","Data Rate":"-","Output Type":"Open Drain, Push-Pull","Channel Type":"Bidirectional","Input Signal":"-","Mounting Type":"Surface Mount","Output Signal":"-","Package / Case":"8-XFDFN","Product Status":"Active","Voltage - VCCA":"1.2 V ~ 3.3 V","Voltage - VCCB":"1.8 V ~ 5.5 V","Translator Type":"Voltage Level","lifecycle_stage":"eol_hot","Number of Circuits":"1","Base Product Number":"PCA9306","Channels per Circuit":"2","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-X2SON (1.4x1)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/43e17d9c17ce8c686f952c07574845d1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PCA9306DQER/alternatives.json"},"ai":{"faq":[{"question":"Is PCA9306DQER compatible with 1.8V and 3.3V?","answer":"Yes.
