Product Summary
The MAX13412EESA is a half-duplex RS-485-/RS-422-compatible transceiver optimized for isolated applications. The device features an internal low-dropout regulator (LDO), one driver, and one receiver. The internal LDO allows the part to operate from an unregulated power supply of up to 28V. The AutoDirection feature reduces the number of optical isolators needed in isolated applications. Other features of the MAX13412EESA include enhanced ESD protection, fail-safe circuitry, slew-rate limiting, and fullspeed operation. The applications of the MAX13412EESA include: Isolated RS-485 Interfaces, Utility Meters, Industrial Equipment, Telecomm Equipment.
