74CB3Q3253BQ

Dual 1-of-4 FET multiplexer/demultiplexer with charge pump

The 74CB3Q3253 is a dual high-bandwidth single-pole, quad-throw FET bus switch.Each switch features a select input (Sn) and an output enable input (nOE). The switch is disabled when the nOE input is HIGH. An internal charge-pump increases the gate voltage of the NMOS pass transistor. The result is improved RON and RON(flat) performance and the ability to switch 5 V signals when VCC=3.3 V.

Features and benefits

  • Wide supply voltage range from 2.3 V to 3.6 V
    • 0 V to 5 V switching with VCC = 2.5 V
    • 0 V to 5 V switching with VCC = 3.3 V
  • Overvoltage switching on switch ports:
  • Switch voltage accepts signals up to 5.5 V
  • 4 Ω (typical) ON resistance
  • 3.5 pF (typical) OFF-state capacitance
  • High bandwidth 0.5 GHz (maximum)
  • Low input/output capacitance minimizes loading and signal distortion
