ORDERING INFORMATION TA PACKAGED DEVICES FEATURES CDCM9102RHBT 32-pin QFN (RHB) package, small tape and reel –40°C to 85°C CDCM9102RHBR 32-pin QFN (RHB) package, tape and reel ABSOLUTE MAXIMUM RATINGS over operating free-air temperature range (unless otherwise noted) (1) MIN TYP MAX UNIT VDDx Supply voltage range(2) –0.5 4.6 V VIN Input voltage range (3) –0.5 VDDx + 0.5 V VOUT Output voltage range(3) –0.5 VDDx + 0.5 V IIN Input current 20 mA IOUT Output current 50 mA Tstg Storage temperature range –65 150 °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 Recommended Operating Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) Supply voltages must be applied simultaneously. (3) The input and output negative voltage ratings may be exceeded if the input and output clamp –current ratings are observed Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback 3 Product Folder Link(s): CDCM9102 |
