The MAX220–MAX249 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..The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 use no external components and are recommended for applications where printed circuit board space is critical.The MAX220–MAX249 are offered in 26 different packages with temperatures from 0 to +70°C up to -55°C to +125°C. See ordering information table at the end of the data sheet for all package and temperature options.ApplicationsInterface TranslationMultidrop RS-232 NetworksPortable Diagnostics Equipment

The MAX202E-MAX213E, MAX232E, and MAX241E are a family of RS-232 and V.28 transceivers with high ±15kV ESD HBM protection and integrated charge pump circuitry for single +5V supply operation. The various combinations of features are outlined in the Selector Guide. The drivers and receivers for all ten devices meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 120kbps when loaded.The MAX211E/MAX213E/MAX241E are available in 28-pin SO and SSOP packages. The MAX202E/MAX232E come in 16-pin TSSOP, narrow SO, wide SO, and DIP packages. The MAX203E comes in a 20-pin DIP/SO package, and needs no external charge-pump capacitors. The MAX205E comes in a 24-pin wide DIP package, and also eliminates external charge-pump capacitors.ApplicationsBattery-Powered EquipmentHandheld EquipmentPortable Diagnostics Equipment

The MAX3080-MAX3089 high-speed transceivers forRS-485/RS-422 communication contain one driver andone receiver. These devices feature fail-safe circuitry,which guarantees a logic-high receiver output when thereceiver inputs are open or shorted. This means thatthe receiver output will be a logic high if all transmitterson a terminated bus are disabled (high impedance).The MAX3080/MAX3081/MAX3082 feature reducedslew-rate drivers that minimize EMI and reduce reflectionscaused by improperly terminated cables, allowingerror-free data transmission up to 115kbps. TheMAX3083/MAX3084/MAX3085 offer higher driver outputslew-rate limits, allowing transmit speeds up to500kbps. The MAX3086/MAX3087/MAX3088's driverslew rates are not limited, making transmit speeds upto 10Mbps possible. The MAX3089's slew rate isselectable between 115kbps, 500kbps, and 10Mbpsby driving a selector pin with a single three-state driver.These transceivers typically draw 375µA of supplycurrent when unloaded, or when fully loaded with thedrivers disabled.All devices have a 1/8-unit-load receiver input impedancethat allows up to 256 transceivers on the bus. TheMAX3082/MAX3085/MAX3088 are intended for halfduplexcommunications, while the MAX3080/MAX3081/MAX3083/MAX3084/MAX3086/MAX3087 are intendedfor full-duplex communications. The MAX3089 is selectablebetween half-duplex and full-duplex operation. Italso features independently programmable receiverand transmitter output phase via separate pins.ApplicationsIndustrial-Control Local Area NetworksLevel TranslatorsRS-422/RS-485 CommunicationsTransceivers for EMI-Sensitive Applications
