Questions answered in these manuals
What is the supply current in low‑power shutdown mode?
In shutdown, the devices typically draw only 1 nA of supply current.
From: Maxim Integrated MAX3080–MAX3089 RS-485/RS-422 Transceivers Datasheet
How do I select half‑duplex or full‑duplex operation?
Use the Half/Full‑Duplex selector pin (H/F): connect H/F to VCC for half‑duplex, or to GND/leave unconnected for full‑duplex.
From: Maxim Integrated MAX3080–MAX3089 RS-485/RS-422 Transceivers Datasheet
What is the maximum data rate of the MAX3089E?
The MAX3089E can operate at up to 10 Mbps, selectable via the slew‑rate selector pin.
