Notes:(1). Stresses above those listed may cause permanent damage to the device. This is a stress rating only, and functional operation at these or any other conditions above those listed in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

          (2). This device employs high-impedance CMOS devices on all signal pins. It must be handled as an ESD-sensitive device. Voltage on any signal pin that exceeds the power supply voltage by more than +0.5 V or drops below ground by more than 0.5 V can induce destructive latchup.
