Detailed Product Description

 

Half-Duplex RS-485-/RS-422-Compatible Transceiver with AutoDirection Control

 

General Description

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 halfduplex 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°C to +85°C temperature range.

 

Features

♦ +5V Operation
