This is a stress rating only and functional opera- tion of the device at these or any other conditions above those indicated in the operation section of this specifica- tion is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. ** Junction temperature depends upon package type, cycle time, loading, ambient temperature and airflow. RECOMMENDED OPERATING CONDITIONS SYM DESCRIPTION MIN NOM MAX UNIT VCC Supply Voltage 4.5 5 5.5 V VIH High-Level Input Voltage 2.4 6.5 V VIL Low-Level Input Voltage 1 -1 0.8 V TA Minimum Operating Temperature -55 °C TC Maximum Operating Case Temperature 125 °C 1. The algebraic convention, where the more negative (less positive) limit is designated as minimum, is used for logic-voltage levels only. |
