1.1 Introduction

This EVM describes the TCA984649-EVM evaluation module (EVM) and the intended use. The board allows for quick prototyping and characterization of TI’s TCA9846 and TCA9849 switch/multiplexer in PW and QFN packages.

The EVM includes the following additional features:

  • Two 3-pin headers for connecting or disconnecting device from external power.
  • Two 3-pin headers for setting the addresses of the device.
  • Eleven 3-lane 3-pin headers to pull up the bus through the desired resistor value.
  • Multiple unpopulated load capacitor footprints for potential additional bus capacitance.
