ABSOLUTE MAXIMUM RATINGS
Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, input or I/O pins may undershoot V
2. Minimum DC input voltage on pins A[9], OE#, and RESET# is -0.5 V. During voltage transitions, A[9], OE#, and RESET#
3. No more than one output at a time may be shorted to V
4. Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
