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.
