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.
RE485
HDPLX
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.
