+5V-Powered, Multichannel RS-232

Drivers/Receivers

The MAX220–MAX249 family of line drivers/receivers isintended for all EIA/TIA-232E and V.28/V.24 communica-tions interfaces, particularly applications where ±12V isnot available.

These parts are especially useful in battery-powered sys-tems, since their low-power shutdown mode reducespower dissipation to less than 5µW. The MAX225,MAX233, MAX235, and MAX245/MAX246/MAX247 useno external components and are recommended for appli-cations where printed circuit board space is critical.

Next-Generation For Low-Voltage, Integrated ESD Applications

MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: +3.0V to +5.5V, Low-Power, Up to1Mbps, True RS-232 Transceivers Using Four0.1µF External Capacitors (MAX3246E Availablein a UCSP Package) For Low-Cost Applications

MAX221E: ±15kV ESD-Protected, +5V, 1µA,

Single RS-232 Transceiver with AutoShutdown
