Electrical Specifications
Note:
Verify with your local sales office that you have the latest datasheet before finalizing a design.
9.1
Absolute Maximum Ratings
Operating ambient temperature (TA) ......................................................... 0°C to 70°C
Storage temperature ............................................................................
65°C to 150°C
All voltages with respect to ground ..............................
0.5 V to V
CC +0.5 V (volts)
Supply voltage (VCC) ........................................................................................ +7.0 V
Power dissipation ................................................................................... 0.25 W (watt)
Note:
Stresses above those listed under Absolute Maximum Ratings can cause permanent damage to the
device. These are stress ratings only and functional operation of the device at these or any
conditions above those indicated in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect device reliability.
9.2
DC Electrical Characteristics
(@ VCC = 5 V ± 5%, TA = 0°C to 70°C)
NOTE: The maximum CLK of 35 MHz applies only to Revision D and later devices; revisions prior to D remain
specified at 33 MHz, maximum. All values in the following tables apply to the 35-MHz specification.
