Frequently Asked Questions
How does the FST16862 connect or disconnect the bus?
When OE is LOW, Port A connects to Port B; when OE is HIGH, a high impedance state exists.
What voltage range should I use for the main power supply (VCC)?
The recommended operating condition for the VCC supply voltage is 4.0V to 5.5V DC.
Are there restrictions on unused control inputs?
Yes, all unused control inputs must be held either HIGH or LOW; they may not float.
Can this component be used in life support systems?
No, the products are not authorized for use as critical components in life support devices without express written approval.
