Description

The THVD4421EVM allows for quick prototyping of TI's RS-485 and RS-232 multiprotocol transceiver (THVD4421). The EVM allows for half and full duplex RS-485 operational modes, 2T2R RS-232 communication, and allows for on-chip diagnostic loopback testing for the RS-232. The THVD4421EVM can be powered by a single supply from 3V to 5.5V or can have a separate logic supply that allows control of the transceiver by controllers operating as low as 1.8V. Multiple speeds are allowed through the use of the slew rate control pin and the ability to use integrated terminations in RS-485 mode.
