The LT1080 and LT1081 are dual driver/receivers that include a charge pump to supply EIA-232 voltage levels from a single 5-V supply. These interface-optimized devices are designed to avoid latch-up and provide a realistic balance between CMOS levels of power dissipation and real-world requirements for ruggedness. The driver outputs are fully protected against overload and can be shorted to 30 V. Unlike CMOS devices, the advanced architecture of the LT1080 and LT1081 does not load the signal line when shut down or when the power is off. Both the receiver and EIA-232 outputs are put into a high-impedance state. An advanced output stage allows driving higher capacitive loads at higher speeds with exceptional resistance to ESD. Applications for these devices include portable computers, battery-powered EIA-232 systems, power-supply generators, terminals, and modems. The LT1080C and LT1081C are characterized for operation from 0C to 70C. The LT1080I and LT1081I are characterized for operation from 40C to 85C. |
