ABSOLUTE MAXIMUM RATINGS
NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
3. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V

NOTES:
1. Typical ratings are not guaranteed. The values listed are at room temperature, 5V.
2. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
3. Capacitive loading on ports 0 and 2 may cause the V
4. Pins of ports 2 and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its

worst cases (capacitive loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to qualify
ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input.
