It prevents the receiver from chattering on slow edges or when the bus is idle and unterminated. For a retrofit into an existing plant-floor network with unknown cable quality, this hysteresis buys you margin without adding external filtering. ## Lifecycle and sourcing posture The MAX490CSA+T carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"MAX490CSA+T RS-485/RS-422 Transceiver, Full Duplex, 2.5 Mbps","metaDescription":"MAX490CSA+T RS-485/RS-422 transceiver, full duplex, 2.5 Mbps data rate, 5 V supply, 0°C to 70°C, 8-SOIC.
