This part is officially marked as obsolete by Texas Instruments. ## Voltage domains — what the VCCA and VCCB ranges mean for your design The VCCA range of 1.2 V to 3.3 V covers the lower-voltage side. The part is bidirectional with auto-direction sensing, handling open-drain buses without a direction-control pin. The two channels per circuit translate two independent signals. ## Package and footprint — 8-LSSOP/8-MSOP (SM8) The package is an 8-lead LSSOP or MSOP with a 2.80 mm body width. The SM8 supplier device package is the TI designation for this footprint. It is a surface-mount package, so reflow soldering is standard.","metaTitle":"TI PCA9306DCTRG4 Voltage-Level Translator, Bidirectional","metaDescription":"Texas Instruments PCA9306DCTRG4 is a 2-channel bidirectional voltage-level translator with auto-direction sensing.
