Product Summary

The MAX249CQH+TD is a +5V-Powered, Multichannel RS-232 Drivers/Receiver. The MAX249CQH+TD is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available. The device is especially useful in battery-powered systems, since its low-power shutdown mode reduces power dissipation to less than 5μW. The MAX249CQH+TD uses no external components and is recommended for applications where printed circuit board space is critical. The applications of the MAX249CQH+TD include Battery-Powered RS-232 Systems, Interface Translation, Low-Power Modems, Multidrop RS-232 Networks, Portable Computing.
