74CB3Q3257PW

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

The 74CB3Q3257 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.

Features and benefits

  • 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

  • 3.5 pF (typical) OFF-state capacitance

  • High bandwidth 0.5 GHz (maximum)

  • Low input/output capacitance minimizes loading and signal distortion

  • Fast switching frequency fmax = 20 MHz (maximum)

  • Low power consumption ICC = 0.4 mA (typical)

  • Control inputs can be driven by TTL or 5 V/3.3 V CMOS outputs

  • IOFF supports partial power-down mode operation

  • Latch-up performance exceeds 100 mA per JESD 78E Class II Level A

  • ESD protection:

    • HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V

    • CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V

  • Specified from -40 °C to +85 °C

Applications

  • Communication infrastructure

  • Bus isolation

  • Memory interleaving

  • Sensor multiplexing

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
