2 / 35 page www.ti.com ABSOLUTE MAXIMUM RATINGS ELECTRICAL CHARACTERISTICS ADS8506 SLAS484B – SEPTEMBER 2007 – REVISED DECEMBER 2007 These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
