1. Voltages are measured with respect to ground
2. These are stress ratings only and functional implication is not implied. Exposure to absolute maximum ratings for extended
periods may affect device reliability.
DC Electrical Characteristics
Unless otherwise stated, 4.5V <= VCC<= 5.5V and over the operating temperature range of 0°C to 70°C (-40°C to +85°C. for N devices). All
voltages are referenced to ground.
