MAXIM MAX13487EESA+T

The MAX13487E/MAX13488E +5V half- duplex, ±15kV ESD- protected RS- 485/RS- 422- compatible transceivers feature one driver and one receiver. The MAX13487E/ MAX13488E include a hot- swap capability to eliminate false transitions on the bus during power- up or live insertion. The MAX13487E/MAX13488E feature Maxim's proprietary AutoDirection 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 MAX13487E features reduced slew- rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables, allowing error- free transmission up to 500kbps. The MAX13488E driver slew rate is not limited, allowing transmit speeds up to 16Mbps. The MAX13487E/MAX13488E 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. The MAX13487E/MAX13488E are available in an 8- pin SO package. The devices operate over the extended - 40℃ to +85℃ temperature range.
