Product Summary

The MAX3218CAP is a RS-232 transceiver. It 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 low- voltage supply. The MAX3218CAP provides a wide +1.8V to +4.25V operating voltage range while maintaining true RS-232 and EIA/TIA-562 voltage levels. The MMAX3218CAP 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. The applications of the MAX3218CAP are (1)Battery-Powered Equipment; (2)Subnotebook Computers; (3)PDAs; (4)Hand-Held Equipment; (5)Peripherals; (6)Cellular Phones.
