CB3Q for switching 5 V signals in 3.3 V isolation and multiplexing applications

Bus switches for hot plug, isolation and multiplexing

Nexperia's CB3Q bus switches are low delay single transistor solutions for multiplexing data buses, hot swapping boards in backplanes, memory interleaving and signal conditioning. CB3Q switches can multiplex 5 V signals when powered at 3.3 V.

Nexperia’s CB3Q bus switch products feature improved RON and RON(flat) performance and the ability to switch 5 V signals when VCC = 3.3 V.

Key features and benefits

  • Wide supply voltage range from 2.3 V to 3.6 V
  • Fast switching frequency
  • Low input/output capacitance minimizes loading and signal distortion

Key applications

  • Telecomunications infrastructure
  • Memory interleaving
  • Industrial control
  • Uni-directional level shifting
  • Cell phones
