VCCA spans 1.2 V to 3.3 V, covering 1.2 V, 1.8 V, and 3.3 V logic families. A 1.8 V MCU on VCCA can talk to a 5 V sensor or legacy peripheral on VCCB without extra glue. The 2-channel per-circuit count means two independent signal lines (e.g., SDA and SCL for I2C) are translated in one package. ## Package and footprint: 8-bump DSBGA The device comes in an 8-UFBGA / 8-DSBGA package (0.5 mm pitch, 1.6 mm x 1.6 mm body). The supplier device package is 8-DSBGA. Surface-mount only — no through-hole option. No exposed thermal pad; power dissipation is low for a level translator, but keep the traces short to the bypass caps on each supply rail. This is the industrial temperature range, covering most commercial, telecom, and outdoor-base-station environments. Not qualified to AEC-Q100, so avoid under-hood automotive or other high-reliability applications without additional qualification data.","metaTitle":"PCA9306YZTR 2-Ch Bidirectional Voltage-Level Translator","metaDescription":"Texas Instruments PCA9306YZTR: 2-channel bidirectional voltage-level translator, VCCA 1.2V–3.3V, VCCB 1.8V–5.5V, auto-direction sensing, 8-DSBGA package.","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-UFBGA, DSBGA","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-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/43e17d9c17ce8c686f952c07574845d1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/PCA9306YZTR/alternatives.json"},"ai":{"faq":[{"question":"Is PCA9306YZTR compatible with 1.8V to 3.3V level shifting?","answer":"Yes.
