The auto flow control and IrDA encoder/decoder are built in — no external logic needed for hardware handshake or infrared serial links. That saves board area and BOM count in a panel controller or gateway that talks to multiple serial devices. ## Active lifecycle — no LTB pressure for new builds The MAX14830ETM+ carries an active lifecycle status and is ROHS3 compliant. There is no last-time-buy window to track.
