CBT3251D

1-of-8 FET multiplexer/demultiplexer

The CBT3251 is a single-pole, 8-throw bus switch. The device features an output enable input (OE) and three select inputs (S0, S1 and S2). When OE is LOW the switch is enabled and the select inputs can be used to connect the A terminal to one of the eight B terminals.

Features and benefits

  • 5 Ω switch connection between two ports

  • Direct interface with TTL levels

  • Overvoltage tolerant control inputs to 5.5 V

  • IOFF circuitry provides partial Power-down mode operation

  • Minimal propagation delay through the switch

  • Latch-up protection exceeds 100 mA per JEDEC standard JESD78 class II level A

  • ESD protection:

    • HBM JESD22-A114E exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

    • CDM JESD22-C101C exceeds 1000 V

  • Specified from -40 °C to +85 °C

Sample

As a Nexperia customer you can order samples via our sales organization or directly via our Online Sample Store: https://extranet.nexperia.com.

Sample orders normally take 2-4 days for delivery.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples.

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.
