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 package thermal impedance is calculated in accordance with JESD 51-7. recommended operating conditions (see Note 2) MIN NOM MAX UNIT VCC, BG VCC Supply voltage 4.75 5 5.25 V BIAS VCC Supply voltage 4.5 5 5.5 V VIH High level input voltage B port 1.62 2.3 V VIH High-level input voltage Except B port 2 V VIL Low level input voltage B port 0.75 1.47 V VIL Low-level input voltage Except B port 0.8 V IOH High-level output current AO port –3 mA IOL Low level output current AO port 24 mA IOL Low-level output current B port 100 mA ∆t/∆v Input transition rise or fall rate Except B port 10 ns/V TA Operating free-air temperature 0 70 °C NOTE 2: To ensure proper device operation, all unused inputs must be terminated as follows: A and control inputs to VCC(5 V) or GND, and B inputs to GND only.
