Note:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. Minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –
2.0V for periods less than 20 ns. Maximum DC voltage on output pins is Vcc + 0.5V
which may overshoot to Vcc + 2.0V for periods less than 20 ns.
3. Operating temperature is for commercial products only defined by this specification.
