The Typical Operating Circuit shows a standard appli-
cation for the MAX3160E. The MAX3160E’s outputs are
multiplexed between RS-232 and RS-485 protocols by
a microprocessor (µP). The µP also directs the shut-
down functions, enable lines, and the duplex of the
MAX3160E. Data is transmitted to the MAX3100 UART
through an SPI™ port. The UART asynchronously
transfers data through the MAX3160E to the pin-select-
ed RS-232 or RS-485 protocal. See Table 14 for com-
monly used cable connections.

The Typical Application Circuit shows the MAX3161E
configured as a multiprotocol bus multiplexer. The
MAX3161E separates the RS-232 and RS-485 lines, but
shares the logic pins between modes. This application
allows the µP to monitor a point-to-point RS-232 bus, and
a multidrop RS-485 interface. The MAX3100 UART asyn-
chronously transfers data through the MAX3161E to the
pin-selected RS-232 or RS-485 protocol.
