RS-232 Driver Output

RS-485/422 Receiver Output/RS-232 Receiver Output

Active-Low Shutdown-Control Input. Drive low to shut

down transmitters and charge pump.

RS-232 Driver Output

Select slew rate limiting for both RS-232 and RS-

485/422. Slew rate limits with a logic-level low.

RS-485/422 Receiver Output

Software-Programmable Pin Functionality. Operates as

RS-485/422 with a logic-level high; operates as RS-232

with a logic-level low.

RS-485/422 Receiver Enable. Logic-level low enables

RS-485/422 receivers.

Software-Programmable Pin Functionality. Operates in

full-duplex mode when low; operates in half-duplex

mode when high.
