The MAX490ESA+ line interface IC is a rugged, full duplex RS 422/RS 485 transceiver in an 8 pin SOIC package. Ideal for industrial, control, sensor network, or automation designs, it provides a reliable, low-power communication channel at up to 2.5 Mbps over long distances, with built-in protection and fail-safe features for demanding environments.
Suppose you’re specifying a single-channel RS 422/485 transceiver for industrial or building automation systems. In that case, the MAX490ESA+ stands out thanks to its efficient power use, robust bus handling, full duplex support, and rugged ±40 °C to +85 °C operating range. It helps streamline design overhead, minimize thermal stress, and reduce system cost — while ensuring signal integrity and reliability in harsh EMI-prone or long-distance installations.
