Dual bus switch with level shifting

The CBTD3306 dual FET bus switch features independent line switches. Each switch is disabled when the associated output enable (nOE) input is HIGH.

The CBTD3306 is characterized for operation from –40 °C to +85 °C.


  • Designed to be used in 5 V to 3.3 V level shifting applications with internal diode
  • 5 Ω switch connection between two ports
  • TTL-compatible input levels
  • Multiple package options
  • Latch-up protection exceeds 100 mA per JESD78B
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • CDM JESD22-C101E exceeds 1000 V
