TLL/UART to RS485

This TLL/UART to RS485 converter circuit uses MAXIM's 485 chip with built-in automatic receive and send function. The function automatically controls the 500Kbps baud rate and automatically recognizes when the baud rate is lower than 500Kbps.
SPECIFICATIONS:
• Recommended voltage: 5V
• ESD protection :±15KV
• Supports multi-machine communication and allows connection to the bus with no more than 128 devices
