MAX485CSA+T datasheet by Maxim Integrated Products

MAX485CSA+T Frequently Asked Questions (FAQs)

• What is the maximum data rate that the MAX485CSA+T can support?
  The MAX485CSA+T can support data rates up to 2.5 Mbps.
• Can the MAX485CSA+T be used in a multi-point application?
  Yes, the MAX485CSA+T can be used in a multi-point application, but it requires an external repeater or a star topology to ensure reliable communication.
• How do I ensure that the MAX485CSA+T is properly terminated?
  To ensure proper termination, a 120-ohm resistor should be connected between the RxD and TxD pins, and a 560-ohm resistor should be connected between the RxD pin and ground.
• What is the maximum cable length that can be used with the MAX485CSA+T?
  The maximum cable length that can be used with the MAX485CSA+T depends on the data rate and the type of cable used. As a general rule, the maximum cable length is 4000 feet at 9600 bps and 1000 feet at 115.2 kbps.
• Can the MAX485CSA+T be used in a noisy environment?
  Yes, the MAX485CSA+T has built-in noise immunity and can operate in noisy environments. It also has a high common-mode rejection ratio (CMRR) to reject electromagnetic interference (EMI).
