Zusammenfassung:The utility model provides a communication interface circuit and a communication device. A first resistor and a second resistor are arranged between the enable end of a MAX485 integrated circuit and the signal output/input end of a MAX232 integrated circuit, so that level signal interference between the MAX485 integrated circuit and the MAX232 integrated circuit is avoided, and the communication device with the communication interface circuit can be connected with an RS232 device or an RS485 device according to the actual need. Therefore, the range of applications of the communication device with the communication interface circuit is expanded.
