1.8V to 4.25V-Powered, True RS-232 Dual Transceiver
_______________General Description
The MAX218 RS-232 transceiver is intended for batterypowered EIA/TIA-232E and V.28/V.24 communications interfaces that need two drivers and two receivers with minimum power consumption. It provides a wide +1.8V to +4.25V operating voltage range while maintaining true RS-232 and EIA/TIA-562 voltage levels. The MAX218 runs from two alkaline, NiCd, or NiMH cells without any form of voltage regulator. A shutdown mode reduces current consumption to 1µA, extending battery life in portable systems.
