Product Summary

The MAX238CWG is a Multichannel RS-232 Driver/Receiver. It is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available. The MAX238CWG is especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5μW. The applications of the MAX238CWG are Portable Computers, Low-Power Modems, Interface Translation, Battery-Powered RS-232 Systems, Multidrop RS-232 Networks.
