Frequently Asked Questions

What is the operating temperature range for this switch?

The CBT3245A can be characterized for operation from -40 to +85 °C.

How does the OE pin control switching?

When OE (Output Enable) is LOW, the switch is ON, connecting port A to port B. When OE is HIGH, it is open in a high-impedance state.

What are the input and output voltage specifications?

The recommended operating conditions specify a VCC between 4.0V and 5.5V for the DC supply voltage.

Is this component designed for life-support applications?

No, these products are explicitly not designed for use in life support appliances or systems.
