Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
4. All voltage values are with respect to VSS.
5. The voltage on any input or output can undershoot to – 2 V for periods less than 20 ns. See Figure 8.
6. The voltage on any input or output can overshoot to 7 V for periods less than 20 ns. See Figure 9.

NOTES: A. CL includes probe and fixture capacitance.
B. AC test conditions are driven at VIH and VIL, Timing measurements are made at VOH and VOL levels on both inputs and outputs.
See Table 9 for values based on VCC operating range..
C. Each device must have a 0.1 F ceramic capacitor connected to VCC and VSS as close as possible to the device pins.
