Can someone recommend an 8 pin DIP RS422 driver IC that has a high
output current potential.  They will be used to transmit NMEA serial
data in marine electronics.  They will output to several paralled
optocouplers.  The 422 driver will not input.  I am looking for a chip
with the maximum output current potential and that can take a shorted
output or output accidently connected to 12VDC.  Data rate will only be
4800 baud.  I normally use high current TTL drivers, but I need to do
some circuits without the negative grounded.
