CBT3257ABQ

Quad 1-of-2 multiplexer/demultiplexer

The CBT3257A is a quad single-pole, dual-throw bus switch. The device features an output enable input (OE) and a select input (S). When OE is LOW the switch is enabled and the select input can be used to connect the nA terminals to either of the associated nB terminals.

Features and benefits

  • 5 Ω switch connection between two ports

  • Minimal propagation delay through the switch

  • Direct interface with TTL levels

  • Overvoltage tolerant control inputs to 5.5 V

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

  • ESD protection:

    • HBM JESD22-A114F exceeds 2000 V

    • MM JESD22-A115-A exceeds 200 V

    • CDM JESD22-C101E exceeds 1000 V

  • Multiple package options

  • 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.
