Part Number:SN65176B
Hi team,
Customer has questions about the Figure 19 of SN65176B datasheet.
1. Does there is a 16.8k ohms resistor between the A/B port?
2. From datasheet, the minimum input resistance is 12K ohm. But from customer's test, the impedance between A/B and GND is infinity. So how to measure the input impedance? Is it the higher, the better?
Thank you.
Marc
