hello folks, I am using a micocontroller to communicate with 18 other microcontrollers via rs489. Using the IC MAX3088, and a 100 ohm resistor across A and B.. Since there are 19 MAX3088, there are also 19 100 ohm in parallel. IS there something wrong with this? the resulting resistance is only about 5.3 ohms. thanks for advice mago
