Frequently Asked Questions
What is the operating voltage range?
The devices operate from 2 V to 5.5 V VCC.
Can the outputs drive bus lines directly?
Yes, the 3-state outputs can drive bus lines directly without interface or pullup components.
How to ensure high-impedance state during power up/down?
Tie OE to VCC through a pullup resistor; min value depends on driver's current-sinking capability.
What ESD protection levels do these devices have?
Exceeds 2000-V HBM, 200-V MM, 1000-V CDM per JESD 22.
