Limiting Clamp Currents on TMS470/TMS570 Digital and Analog Inputs (Rev. A)

Texas Instruments

Published Date: 12/08/2014

Description

Digital and Analog input pins require protection from input voltages that are negative or positive exceeding the maximum input levels. This is a practical explanation of using the Electrostatic Discharge (ESD) protection diodes that are part of the input pins to help limit the voltage if input current is limited.
