Hi team,
The recommended supply voltage of SN65LBC184 is 5V +/-5%. This is not typical. Typically a 5V RS485 interface device is specified for 5V +/-10% supply. I do not know why? This kind of requirement will complicated the design of isolated dc/dc for RS485, since most of 5V to 5V isolated dcdc module is +/-10.
My customer wants to know is it possible to power SN65LBC184 with 5V +/-10% supply? is there any potential issue or performance degradation?
Thank you,
John
