ELECTRICAL OPERATING CHARACTERISTICS
VCC = Full range, TA = -40°C to +85°C unless otherwise noted. Typical values at TA = +25°C and VCC = 5V for the
L/M/J versions, VCC = 3.3V for the T/S versions, VCC = 3V for the R version and VCC = 2.5V for the Z version.

Notes:
(1) 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 outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
