The -40°C to 85°C industrial temperature range covers outdoor telecom cabinets and factory-floor controllers. ## Active production — no LTB clock ticking ROHS3 compliant, so it passes current European and global environmental requirements. For a BOM line that needs a simple bus isolation switch with a long procurement horizon, this one is safe to qualify into new designs without worrying about a last-time-buy window closing.","metaTitle":"SN74CB3T3306DCUR Bus Switch, 2.3V–3.6V, 8-VSSOP","metaDescription":"TI SN74CB3T3306DCUR bus switch, 2 independent 1:1 circuits, 2.3V–3.6V supply, -40°C to 85°C, 8-VSSOP.

Each circuit is a single-pole single-throw pass gate that can be controlled separately."},{"question":"How does SN74CB3T3306DCUR compare to similar bus switches?","answer":"Within the 74CB family, the key differentiator is the 2.3V to 3.6V supply range that supports both 2.5V and 3.3V logic without an external regulator. The dual independent channels in the small 8-VSSOP package give it a board-area advantage over two single-channel switches. For applications needing wider voltage tolerance or higher channel count, look at the 74CB family's other density options."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/SN74CB3T3306DCUR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/SN74CB3T3306DCUR when reusing this data.
