LT1081CSW#PBF

LT1081 is an advanced low power RS232 driver/ receiver with charge pump to guarantee absolutely no latch up. These interface optimized devices 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 ±30V. Unlike CMOS, the advanced architecture of the device does not load the signal line when “shut down” or when power is off. Both the receiver and RS232 outputs are put into a high impedance state. An advanced output stage allows driving higher capacitive loads at higher speeds with exceptional ruggedness against ESD. It is widely used in application such as portable computers, battery-powered RS232 systems, power supply generator, terminals, modems etc.
