The 1.2 V floor on VCCA is critical for designs using the latest sub-1.8 V FPGAs or MCUs; the 5.5 V ceiling on VCCB accommodates 5 V-tolerant I2C buses without external clamping. ## Package and footprint: SM8 (8-LSSOP/8-MSOP) The PCA9306DCTTE4 comes in an 8-lead LSSOP/MSOP package (2.80 mm width, 0.110\" body), designated as supplier device package SM8. It is surface-mount only, shipped in Tape & Reel. No thermal pad is present, so power dissipation is limited to the package's natural capability. For new designs, the active PCA9306DCUR (same SM8 package, different reel suffix) or the broader PCA9306 family in other packages (e.g., DCT, DCU) should be evaluated for pin compatibility and electrical equivalence.","metaTitle":"PCA9306DCTTE4 Voltage-Level Translator, 1.2–5.5 V, Obsolete","metaDescription":"TI PCA9306DCTTE4 dual bidirectional voltage-level translator for I2C/SMBus.
