The MAX1482 and MAX1483 are low-power transceiversfor RS-485 and RS-422 communication. Bothfeature slew-rate-limited drivers that minimize EMI andreduce reflections caused by improperly terminatedcables. Data rates are guaranteed up to 250kbps.The MAX1482/MAX1483 draw only 20µA of supply current.Additionally, they have a low-current shutdownmode that consumes only 0.1µA. Both parts operatefrom a single +5V supply.Drivers are short-circuit current limited and are protectedagainst excessive power dissipation by thermalshutdown circuitry that places the driver outputs into ahigh-impedance state. The receiver input has a fail-safefeature that guarantees a logic-high output if the inputis open circuit.The MAX1482 is full duplex and the MAX1483 is halfduplex. Both parts have a 1/8-unit-load input impedancethat guarantees up to 256 transceivers on the bus.ApplicationsIndustrial Control Local Area NetworksLarge 256-Node LANsLow-Power RS-485/RS-422 NetworksTransceivers for EMI-Sensitive Applications

The MAX1488E quad, low-power line driver is designed for EIA/TIA-232, EIA/TIA-562, and CCITT V.28 communications in harsh environments. Each transmitter output is protected against ±15kV electrostatic discharge (ESD) shocks. The inputs are TTL and CMOS compatible with minimal loading. The outputs feature internally controlled slew-rate limiting and current limiting. This device has a guaranteed 120kbps data rate. Power-supply current is less than 180µA over a ±4.5V to ±13.2V supply voltage range.The MAX1488E is pin compatible with the MC1488, MC14C88, SN75188, SN75C188, DS1488, and DS14C88. It is available in 14-pin plastic DIP and SO packages.ApplicationsEquipment Meeting IEC 1000-4-2 (Formerly IEC 801-2) or ±15kV ESD ProtectionInterfacing Data Terminal Equipment (DTE) with Data Circuit-Terminating Equipment (DCE)ModemsPC Motherboards

The MAX218 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. It provides a wide +1.8V to +4.25V operating voltage range while maintaining true RS-232 and EIA/TIA-562 voltage levels. The MAX218 runs from two alkaline, NiCd, or NiMH cells without any form of voltage regulator.A shutdown mode reduces current consumption to 1µA, extending battery life in portable systems. While shut down, all receivers can remain active or can be disabled under logic control, permitting a system incorporating the CMOS MAX218 to monitor external devices while in low-power shutdown mode.A guaranteed 120kbps data rate provides compatibility with popular software for communicating with personal computers. Three-state drivers are provided on all receiver outputs so that multiple receivers, generally of different interface standards, can be wire-ORed at the UART. The MAX218 is available in 20-pin DIP, SO, and SSOP packages.ApplicationsBattery-Powered ApplicationsComputers: Desktop, Workstation, ServerInstrumentsModemsPeripheralsPrinters

The MAX250 and MAX251 chip set form the heart of a complete, electronically isolated, RS-232 dual transmitter/receiver. By combining many functions on two chips, the cost and complexity required for an isolated digital interface is greatly reduced. Four low cost optocouplers, four capacitors, a diode and a small pot-core type transformer are all that are required to complete a 19.2k baud transceiver. Faster data rates are possible by using high speed optocouplers. In addition to the driving and receiving circuitry for the optocouplers, the chip set includes a push-pull transformer driver to supply power to the interface's isolated side.Other convenient features include single +5V operation, a low power shutdown mode, and output enable control for three-state operation. The MAX250 and MAX251 are supplied in 14 lead DIP, 14 lead small outline and 20 leadless chip carrier packages.The MAX252 has all the required components for RS-232 communication in a single package.ApplicationsBridge Ground DifferentialsData Links To Analog CircuitsHigh Noise Data CommunicationsIndustrial Communications
