Frequently Asked Questions
How do I power on or off the switch ports?
When OE is LOW, Port 1A connects to Port 1B, and Port 2A connects to Port 2B. When OE is HIGH, there is a high impedance state between the A and B Ports.
What should I do with unused control inputs?
The unused control inputs must be held either HIGH or LOW; they may not float.
Is this device suitable for life support systems?
No, Fairchild states that its products are not authorized for use as critical components in life support devices without the express written approval of the corporation's President.
What is the switch's recommended maximum on resistance?
The typical On Resistance (R_ON) is 4.5 Ω (when V=0V and I=64 mA).
In what temperature range can this device be stored?
The Storage Temperature Range is specified as -65°C to +150 °C.
