1µA Supply Current, 1.8V to 4.25V-Powered RS-232 Transceiver with AutoShutdown™
_______________General Description
The MAX3218 RS-232 transceiver is intended for battery-powered EIA/TIA-232E and V.28/V.24 communications interfaces that need two drivers and two receivers with minimum power consumption from a single lowvoltage supply. It provides a wide +1.8V to +4.25V operating voltage range while maintaining true RS-232 and EIA/TIA-562 voltage levels. The MAX3218 runs from two alkaline, NiCd, or NiMH cells without any form of voltage regulator. A guaranteed 120kbps data rate provides compatibility with popular software for communicating with personal computers. Supply current is reduced to 1µA with Maxim’s new AutoShutdown™ feature.
