ANALOG DEVICES LT1081ISW#PBF RS232 Transceiver, 120Kbps, 5 to 5.5V, -40°C to 85°C, WSOIC-18

LT1081ISW#PBF is a advanced low power 5V RS232 dual driver/receiver. This interface optimized device provides 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 used in applications such as portable computers, battery-powered RS232 systems, power supply generator, terminals, modems.

• Three-state outputs are high impedance when off
• Absolutely no latchup, only needs 1µF capacitors
• Driver logic input current is 5µA typical at (VIN ? 2V, TA = 25°C)
• Driver slew rate is 15V/µs typical at (RL = 3K, CL = 51pF, TA = 25°C)
• Driver output leakage current is 10µA typical at (SHUTDOWN, VOUT = ±30V)
• Receiver input resistance is 5Kohm typical at (VIN = ±10V, TA = 25°C)
• Supply current is 12mA typical at (TA = 25°C)
• Receiver output short-circuit current is -20mA typical at (sinking current, VOUT = VCC)
• Operating temperature range from -40°C to 85°C
• 16-lead plastic WSOIC package
