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. NOTES: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 2. This value is limited to 4.6 V maximum. 3. The package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions MIN MAX UNIT VCC Supply voltage 3 3.6 V IOH‡ High-level output current –25 mA IOL‡ Low-level output current 25 mA ∆t/∆v Input transition rise or fall rate Outputs enabled 5 ns/V TA Operating free-air temperature –40 85 °C ‡ See Figures 1 and 2 for typical I/O ranges. |
