At 20Mbps, the MAX3045BCUE+ supports high-speed RS422/RS485 links such as camera data, industrial encoder feedback, or multi-drop instrumentation busses. This is roughly double the 10Mbps ceiling of many legacy RS485 drivers, so it keeps the bus timing margin cleaner on longer cable runs or daisy-chained nodes. The 4/0 driver/receiver count means you need an external RS485 receiver on the same bus if bidirectional communication is required.

Frequently asked questions
What is the maximum data rate of MAX3045BCUE+?
The MAX3045BCUE+ supports a maximum data rate of 20Mbps over RS422 or RS485 protocols.
How many drivers does MAX3045BCUE+ have?
The MAX3045BCUE+ has 4 drivers and 0 receivers — it is a pure transmit-side line driver.
What is the closest pin-compatible alternative to MAX3045BCUE+?
Within the same 16-TSSOP footprint, the industrial-temperature MAX3045EUE+ (-40°C to +85°C) is pin-compatible and shares the same 20Mbps data rate and 4/0 driver/receiver configuration. For a part with integrated receivers, the MAX3045 series does not offer a drop-in; you would need a different family such as the MAX3082 series.
