3 / 9 page SN74SSQEB32882 www.ti.com SCAS896-PUB – JUNE 2010 ABSOLUTE MAXIMUM RATINGS Table 3. Absolute Maximum Ratings Over Operating Free-Air Temperature Range(1) PARAMETER VALUE UNIT VDD Supply voltage –0.4 to +1.975 V VI Receiver input voltage See (2) and (3) –0.4 to VDD + 0.5 V VREF Reference voltage –0.4 to VDD + 0.5 V VO Driver output voltage See (2) and (3) –0.4 to VDD + 0.5 V IIK Input clamp current VI < 0 or VI > VDD –50 mA IOK Output clamp current VO < 0 or VO > VDD ±50 mA IO Continuous output current 0 < VO < VDD ±50 mA ICCC Continuous current through each VDD or GND pin ±100 mA Tstg Storage temperature –65 to +150 °C (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. (3) This value is limited to 1.975 V maximum. Table 4. Case Temperature vs Speed Node PARAMETER DDR3-800 DDR3-1066 DDR3-1333 DDR3-1600 DDR3-1866 UNIT Tcase(max) Maximum case temperature (1) +109 +108 +106 +103 +101 °C (1) The temperature values fit to JEDEC RAW cards A, B, and C. The user must keep Tcase below the specified values in order to keep the junction temperature below +125°C. Other combinations of features and termination resistors can require lower case temperature and extra cooling. These combinations depend on the specific application.
