_______________General Desc ription
The MAX214 +5V RS-232 transceiver provides a com-
plete, 8-line, software-configurable, DTE or DCE port
RS-232 interface. Tx, Rx, RTS, CTS, DTR, DSR, DCD,
and RI circuits can be configured as either Data
Terminal Equipment (DTE) or Data Circuit-Terminating
Equipment (DCE) using the DTE/DCE control pin. The
MAX214 eliminates the need to swap cables when
switching between DTE and DCE configurations.
