Maxim Integrated MAX3171/MAX3173 Multiprotocol Transceiver Datasheet
The MAX3171 and MAX3173 are three‑driver/three‑receiver multiprotocol transceivers that operate from a single +3.3 V supply. They form a complete DTE/DCE interface together with the MAX3170 and MAX3172/3174 and support V.28 (RS‑232), V.10/V.11 (RS‑449, V.36, EIA‑530, X.21, RS‑423) and V.35 protocols.
Key features include a dual charge‑pump that generates both positive and negative output voltages, a no‑cable mode that reduces supply current, fail‑safe receiver operation, and software‑selectable mode pins (M0, M1, M2, DCE/DTE) for protocol selection. The devices are offered in a 28‑pin SSOP package and require only four surface‑mount capacitors for charge‑pump operation.

Questions answered in these manuals
What current does the device draw in no‑cable mode?
In no‑cable mode the supply current is less than 8 mA.
From: Maxim Integrated MAX3171/MAX3173 Multiprotocol Transceiver Datasheet
How are the communication protocols selected?
The state of mode select pins M0, M1, M2 and the DCE/DTE pin determines which serial interface protocol is selected.
