TCA6507EVM User's Guide
This user's guide describes the characteristics, operation, and use of the TCA6507EVM evaluation module. This
document also reviews various aspects of hardware configuration and program operation, allowing designers to
evaluate the TCA6507 at different loading conditions (pullup resistors and bus capacitance), VCC voltages, and
output loads as needed. Throughout this document, the terms: evaluation board, evaluation module, and EVM
are synonymous with the TCA6507EVM. This user's guide also includes an electrical schematic, printed circuit
board (PCB) layout drawings, and a parts list for the EVM.
