It operates from a single 4.5 V to 5.5 V supply and handles data rates up to 120 kbps.
At 120 kbps, this transceiver is sized for standard UART communication at 115200 baud and below — common for industrial sensors, terminal interfaces, and configuration ports. It will not support higher-speed RS-232 applications like video or high-throughput data loggers that need 1 Mbps or more.
5 V only — plan the power rail accordingly
The supply range is 4.5 V to 5.5 V, so this part is a 5 V-only device. If your design uses a 3.3 V logic core, you will need a separate 5 V rail or a level translator between the UART and the transceiver. The through-hole PDIP package (16-DIP, 0.300" width) is a legacy footprint — verify board clearance and hole size if retrofitting into an existing layout.
