74CB3Q3257-Q100

4-bit 1-of-2 FET multiplexer/demultiplexer with charge pump

The 74CB3Q3257-Q100 is a quad high-bandwidth single-pole, double-throw FET bus switch. The device features one select input (S) and one output enable input (OE). The switch is disabled when the OE 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.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 3) and is suitable for use in automotive applications.

Features

  • Automotive product qualification in accordance with AEC-Q100 (Grade 3)
    • Specified from -40 °C to +85 °C
  • Wide supply voltage range from 2.3 V to 3.6 V
  • Overvoltage switching on switch ports:
    • 0 V to 5 V switching with VCC = 2.5 V
    • 0 V to 5 V switching with VCC = 3.3 V
  • 4 Ω (typical) ON resistance
