Half-Duplex RS-485-/RS-422-Compatible  
Transceiver with AutoDirection Control  
7/MAX1348E  
General Description  
Features  
The MAX13487E/MAX13488E +5V, half-duplex, ±15ꢀV  
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.

AutoDirection Enables Driver Automatically on  
Transmission  
Hot-Swappable for Telecom Applications  
Enhanced Slew-Rate Limiting Facilitates Error-  
Free Data Transmission (MAX13487E)  
High-Speed Version (MAX13488E) Allows for  
Transmission Speeds Up to 16Mbps  
Extended ESD Protection for RS-485 I/O Pins  
± 15kV Human Body Model  
The MAX13487E/MAX13488E feature Maxim’s propri-  
etary AutoDirection control. This architecture maꢀes 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.  
1/4-Unit Load, Allowing Up to 128 Transceivers on  
the Bus  
The MAX13487E features reduced slew-rate drivers  
that minimize EMI and reduce reflections caused by  
improperly terminated cables, allowing error-free trans-  
mission up to 500ꢀbps. The MAX13488E driver slew  
rate is not limited, allowing transmit speeds up to  
16Mbps.

CODE  
The MAX13487E/MAX13488E feature a 1/4-unit load  
receiver input impedance, allowing up to 128 trans-  
ceivers on the bus. These devices are intended for half-  
duplex communications. All driver outputs are  
protected to ±15ꢀV ESD using the ꢁuman ꢂody Model.  
The MAX13487E/MAX13488E are available in an 8-pin  
SO pacꢀage. The devices operate over the extended  
-40°C to +85°C temperature range.
