Product Summary

The MAX238CNG is a line driver/receiver intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available. The MAX238CNG is especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5μW. The MAX238CNG uses no external components and are recommended for applications where printed circuit board space is critical.
