CBT3257AD

Quad 1-of-2 multiplexer/demultiplexer

The CBT3257A is a quad 1-of-2 high-speed TTL-compatible multiplexer/demultiplexer. The low ON resistance of the switch allows inputs to be connected to outputs without adding propagation delay or generating additional ground bounce noise.

Output enable (OE) and select-control (S) inputs select the appropriate nB1 and nB2 outputs for the nA input data.

The CBT3257A is characterized for operation from -40 °C to +85 °C.

Features

  • 5 Ω switch connection between two ports
  • TTL-compatible input levels
  • Minimal propagation delay through the switch
  • 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
