+5V-Powered, Multichannel RS-232 Drivers/Receivers The MAX220MAX249 family of line drivers/receivers is intended for all EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where ±12V is not available. These parts are especially useful in battery-powered systems, since their low-power shutdown mode reduces power dissipation to less than 5μW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.
Description: The MAX232EPE is a dual driver/receiver that includes a capacitive voltage generator to supply EIA-232 voltage levels from a single 5V supply. Features: Operates from a single 5V supply ±15kV ESD protection on all pins Low power consumption 5V tolerant inputs Low shutdown current Low-power shutdown mode 0.1μF charge-pump capacitors included Available in 8-pin PDIP, SO, and TSSOP packages Applications: RS-232 line drivers/receivers Modems ISDN terminal adapters Set-top boxes IrDA transceivers PCMCIA cards Handheld computers Portable data terminals (For reference only)
