Signal Switches, Multiplexers, Decoders FAQ

How does the output enable (OE) input function?

When OE is LOW, the switch connects port A to port B. When OE is HIGH, each switch is disabled, placing the outputs in a high-impedance state.

What is the recommended supply voltage range?

The recommended operating conditions specify a supply voltage (VCC) range of 4.5 V to 5.5 V.

Does the device support bidirectional data flow?

Yes, the CBT3861 provides ten bits of bidirectional bus switching, allowing data to flow between port A and port B when enabled.
