DC CHARACTERISTICS
VCC = 5V, VSS = 0V, -55°C ≤ TA ≤ +125°C
NOTE:
Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage
to the device. This is a stress rating only and functional operation of the device at these or any other
conditions greater than those indicated in the operational sections of this specication is not implied.
Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
