The MAX3535E/MXL1535E is an RS-485/RS-422 transceiver with 2500VRMS ESD protection, supporting 1000kbps RS-485/RS-422 communication, and operating voltage range of +3V to +5.5V.
The Maxim MAX3535E and MXL1535E are isolated transceiver families supporting full‑duplex RS‑485/RS‑422 communication up to 1000 kbps. They provide high common‑mode voltage isolation (up to 2500 V) and robust ESD protection.
The devices operate from a 3 V‑5.5 V logic‑side supply and a 3.13 V‑7.5 V isolated‑side supply, feature a 28‑pin wide‑SO package, and are rated for –40 °C to +85 °C operation. Key electrical parameters, isolation ratings, and pin configurations are detailed in the following sections.
