These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. recommended operating conditions (see Note 2) MIN MAX UNIT VCC Supply voltage 4.5 5.5 V VIH High-level input voltage 2 V VIL Low-level input voltage 0.8 V VI Input voltage 0 VCC V IOH High-level output current –32 mA IOL Low-level output current 64 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 5 ns/V TA Operating free-air temperature –40 85 °C NOTE 2: Unused or floating pins (input or I/O) must be held high or low. |
