Maxim Integrated MAX3097E/MAX3098E Triple RS-422/RS-485 Receiver Datasheet
The MAX3097E and MAX3098E are high‑speed, triple RS‑422/RS‑485 receivers designed for motor‑shaft encoders and other applications requiring robust fault detection. Each receiver provides independent fault‑status outputs for open‑circuit, short‑circuit, low differential voltage, and common‑mode range violations, with a programmable delay to avoid false alarms at slow edge rates.
The devices operate from a 3 V to 5.5 V supply, support data rates up to 32 Mbps, and feature +15 kV ESD protection (Human Body Model and IEC 1000‑4‑2 standards). They are offered in a 16‑pin QSOP package and include detailed pin descriptions, electrical characteristics, and typical operating curves.
