The Texas Instruments MAX3243ECPWR is an RS-232 line driver and receiver in a 28-pin TSSOP package, supplied on tape and reel. It integrates three drivers/transmitters and five receivers in a single full-duplex transceiver supporting data rates to 500 kbps and 16 total I/Os. The device operates from 3 V to 3.6 V or 4.5 V to 5.5 V supplies at 1 mA maximum supply current, with 150 ns propagation delay. MAX3243ECPWR is rated -40 C to +85 C and is lead free and RoHS compliant.

An RS-232 transceiver translates a controller's logic-level UART signals to and from the higher-voltage bipolar levels the RS-232 standard requires, generating those levels on-chip from a single supply. With three transmitters and five receivers, the MAX3243ECPWR suits full-handshake serial ports that need control lines alongside TX and RX, rather than a minimal two-wire link. Common applications include industrial equipment consoles, point-of-sale and payment terminals, test and measurement instruments, networking gear management ports, and legacy peripheral interfaces on embedded computers. Buyers are typically embedded and industrial hardware teams maintaining or designing serial connectivity where RS-232 remains the field standard.
