PIN CONFIGURATIONS
NOTES:
1. All Vcc pins must be connected to the power supply.
2. All GND pins must be connected to the ground supply.
3. This text does not indicate orientation of the actual part-marking.
ABSOLUTE MAXIMUM RATINGS
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
2. VTERM must not exceed Vcc + 0.5 for more than 25% of the cycle time
