Frequently Asked Questions
What is the required procedure for using the Output Enable (OE) pins?
During power up or down, OE must be tied to V through a pull-up resistor to ensure the high-impedance state.
What voltage range does this transceiver operate in while maintaining 5V tolerance?
It operates at low voltages ideal for applications between 2.3V–3.6V, utilizing 5V tolerant inputs and outputs.
What must be done with unused data pins to prevent errors?
All unused inputs or I/O's must be explicitly held HIGH or LOW; they may not float.
What is the recommended operating voltage range for this device?
The recommended supply voltage for operation is between a minimum of 2.0 V and a maximum of 3.6 V.
