The MAX2202x/F Isolated RS-485/RS-422 Transceivers feature Analog Devices' proprietary AutoDirection control making these devices ideal for applications such as isolated RS-485 ports, where the driver input is used in conjunction with the driver-enable signal to drive the differential bus.
The MAX22025, MAX22027, MAX22025F, and MAX22027F feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improper termination of cable allowing error-free transmission up to 0.5Mbps. The MAX22026, MAX22028, MAX22026F, and MAX22028F driver outputs are not slew-rate limited, allowing transmit speeds up to 16Mbps.
The receiver output of the MAX22025, MAX22026, MAX22025F, and MAX22026F does not follow (VA-VB) when the device is in the driver-enabled state. The receiver output on the MAX22027, MAX22028, MAX22027F, and MAX22028F always follows (VA-VB).
The driver outputs and receiver inputs are protected from ±10kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the Human Body Model (HBM). These devices are available in a compact 8-pin wide-body SOIC package and operate over the -40°C to +85°C temperature range.
