The RS422 to TTL (UART) module utilizes the MAX490 chip by maxim integrated. The Max490 is a low-power transceiver for RS-485 and RS422 communication, and it contains one driver and one receiver. The MAX490 features reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables. In addition, the driver slew rates of the MAX490 are not limited, thus allowing error-free data transmission up to 2.5Mbps.
