10-bit bus switch with 5-bit output enables

The CBT3384 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 CBT3384 device is organized as two 5-bit bus switches with two separate output enable (1OE, 2OE) inputs. When nOE is LOW, the switch is on and port A is connected to the B port. When nOE is HIGH, each switch is disabled.

The CBT3384 is characterized for operation from -40 °C to +85 °C.


  • 5 W switch connection between two ports
  • TTL-compatible control input levels
  • Multiple package options
  • See CBTD3384 for CBT3384 with level shifting diodes
  • Latch-up protection exceeds 100 mA per JESD78
  • ESD protection:
    • HBM JESD22-A114E exceeds 2000 V
    • CDM JESD22-C101C exceeds 1000 V
