40 Mbps RS485 bus transceiver in 8-SOIC
The MAX3468ESA+ is a single-channel half-duplex transceiver that handles RS422 and RS485 protocols at data rates up to 40 Mbps. The 1/1 driver/receiver count means one differential pair carries bidirectional traffic on a shared bus — typical for multi-drop industrial networks where each node listens and transmits on the same twisted pair. The 50 mV receiver hysteresis filters out noise on long cable runs where reflections can sit just below the logic threshold.
