10-bit bus switch with output enable

The CBT3861 provides ten bits of high-speed TTL-compatible bus switching. The low ON resistance of the switch allows connections to be made with minimal propagation delay.

The CBT3861 device is organized as one 10-bit bus switches with one output enable (OE) input. When OE is LOW, the switch is on and port A is connected to the B port. When OE is HIGH, each switch is disabled.

The CBT3861 is characterized for operation from –40 ℃ to +85 ℃.


  • 5 Ω switch connection between two ports
  • TTL-compatible control input levels
  • Multiple package options
  • Latch-up protection exceeds 100 mA per JESD78
  • ESD protection:
    • HBM JESD22-A114F exceeds 2000 V
    • CDM JESD22-C101C exceeds 1000 V
