2 / 34 page  UCD9246 SLVSA34 – JANUARY 2010 www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. ORDERING INFORMATION(1) OPERATING TEMPERATURE ORDERABLE PART PIN COUNT SUPPLY PACKAGE TOP SIDE RANGE, TA NUMBER MARKING UCD9246RGCR 64-pin Reel of 2000 QFN UCD9246 –40°C to 125°C UCD9246RGCT 64-pin Tray of 250 QFN UCD9246 (1) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com. ABSOLUTE MAXIMUM RATINGS (1) VALUE UNIT Voltage applied at V33D to DGND –0.3 to 3.8 V Voltage applied at V33A to AGND –0.3 to 3.8 V Voltage applied to any pin(2) –0.3 to 3.8 V Storage temperature (TSTG) –40 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 recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltages referenced to GND. RECOMMENDED OPERATING CONDITIONS over operating free-air temperature range (unless otherwise noted) MIN NOM MAX UNIT V Supply voltage during operation, V33D, V33DIO, V33A 3 3.3 3.6 V TA Operating free-air temperature range(1) –40 125 °C TJ Junction temperature (1) 125 °C (1) When operating, the UCD9246’s typical power consumption causes a 15°C temperature rise from ambient.
