MAX14780E
+5.0V, ±30kV ESD-Protected, Fail-Safe,
Hot-Swap, RS-485/RS-422 Transceiver
General Description
The MAX14780E is a +5V, ±30kV HBM ESD half duplex
RS-485/422 transceiver.
The MAX14780E features reduced slew-rate drivers that
minimize EMI and reduce reflections caused by improp-
erly terminated cables, allowing error-free data transmis-
sion up to 500kbps.
The MAX14780E is available in an 8-pin SO and PDIP
packages operating over a temperature range from
-40°C to +85°C.
