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 propri-
etary 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 trans-
mission 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 trans-
ceivers 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°C to +85°C temperature range.
