MAX323CPA+ datasheet by Maxim Integrated Products

MAX323CPA+ Frequently Asked Questions (FAQs)

• What is the maximum data rate that the MAX323CPA+ can handle?
  The MAX323CPA+ can handle data rates up to 250kbps, but it's recommended to limit the data rate to 120kbps for reliable operation.
• Can I use the MAX323CPA+ with a 3.3V supply voltage?
  Yes, the MAX323CPA+ can operate with a supply voltage as low as 3.0V, but the recommended operating range is 4.5V to 5.5V.
• How do I ensure that the MAX323CPA+ is properly terminated?
  The MAX323CPA+ requires a 1kΩ to 10kΩ pull-up resistor on the receiver input (RIN) to VCC, and a 1kΩ to 10kΩ pull-down resistor on the driver output (DOUT) to GND.
• What is the maximum cable length that can be used with the MAX323CPA+?
  The maximum cable length depends on the data rate and the quality of the cable. As a general rule, the MAX323CPA+ can drive cables up to 100 feet (30 meters) at 120kbps, but it's recommended to use shorter cables for reliable operation.
• Can I use the MAX323CPA+ in a multi-point configuration?
  Yes, the MAX323CPA+ can be used in a multi-point configuration, but it's recommended to use a common-mode termination resistor (RTERM) to ensure reliable operation.
