MAX13487EESA+ Half-Duplex RS-485 And RS-422 Compatible Transceiver

The MAX13487EESA+ 5V, half-duplex, ±15kV ESD-protected RS-485/RS-422-compatible transceivers feature one driver and one receiver. The MAX13487EESA+ include a hot-swap capability to eliminate false transitions on the bus during power-up or live insertion. The MAX13487EESA+ feature Maxim’s proprietary Auto-Direction control. This architecture makes the devices ideal for applications, such as isolated RS-485 ports, where the driver input is used in conjunction with the driver-enable signal to drive the differential bus.

The MAX13487EESA+ features reduced slew-rate driver that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error-free transmission up to 500kbps. The MAX13487EESA+ feature a 1/4-unit load receiver input impedance, allowing up to 128 transceivers on the bus. These devices are intended for half-duplex communications. All driver outputs are protected to ±15kV ESD using the Human Body Model. Then MAX13487EESA+ are available in an 8-pin SO package. The devices operate over the extended-40°C to +85°C temperature range.

Applications:

• Isolated RS-485 Interfaces
