Stresses above 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
above those indicated in the operation sections of the
specifications is not implied. Exposure to Absolute
Maximum Rating conditions for extended periods may
affect device reliability.
ELECTRICAL SPECIFICATIONS
Electrical Characteristics: VCC = 5V for L/M versions, VCC = 3.3V for T/S versions, VCC = 3V for R version, VCC =2.0V for F
version. Unless otherwise noted, TA = -40°C to +85°C. Typical values are at TA = +25°C. (Note 1).
