CBT3257A

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
