85 / 95 page ![]() 85 AT43USB353M 3307B–USB–4/04 Electrical Specification Absolute Maximum Ratings Stresses beyond those listed below may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Expo- sure to absolute maximum rating conditions for extended periods may affect device reliability. Note: VCEXT is the voltage of CEXT1, CEXT2 and CEXTA. DC Characteristics The values shown in Table 28 are valid for TA = 0 °C to 85°C, VCC = 4.4 to 5.25V, unless oth- erwise noted. Table 27.
