Notes :
1. Operating temperature is for commercial product defined by this spec.
2. Minimum D.C. input voltage is -0.5 V. During transitions, inputs may undershoot, to -2.0 V for periods less than 20 ns.
Maximum D.C. voltage on output pins is VCC+0.5 V, which may overshoot to VCC + 2.0 V for periods less than 20 ns.
Warning:
Stressing the device beyond the “Absolute Maximum Rating” may cause permanent damage. This is stress rating only.
Operation beyond the “operating conditions” is not recommended and extended exposure beyond the “operating
conditions” may affect device reliability.
