描述 Description

The MAX3485E is a 3.3V powered, half-duplex, low-power RS-485 transceiver that fully meets the

requirements of the TIA/EIA-485 standard.

The MAX3485E includes a driver and a receiver, both of which can be independently enabled and

disabled. When both are disabled, both the driver and the receiver output a high impedance state. The

MAX3485E has a 1/8 load that allows 256 MAX3485E transceivers to be connected to the same

communication bus. Error-free data transfer of up to 12Mbps is possible.

The MAX3485E operates from a voltage range of 3.0 to 3.6V and features fail-safe, over

temperature protection, current limit protection, over-voltage protection, and other functions.
