For more information please visit our website at TI.com/rs232 for our complete device portfolio. We have an online interface selection guide which covers both the RS232 and USB transceiver portfolios. We have an application note for the low voltage single-supply 232 standard solutions, and there is a detailed cross-reference tool if you are looking for a TI drop-in replacement. EVM boards are also available for both the RS232 product lines and USB transceivers.
