ANALOG DEVICES LT1081IN#PBF RS232 Driver/Receiver, 120 Kbps, 6V Supply, -40 to 85 °C, PDIP-16

LT1081IN#PBF is an advanced low power 5V RS232 dual driver/receiver. The LT1081 is the only dual RS232 driver/ receiver with charge pump to guarantee absolutely no latchup. This interface optimized device provides a realistic balance between CMOS levels of power dissipation and real world requirements for ruggedness. The driver output is fully protected against overload and can be shorted to ±30V. Unlike CMOS, the advanced architecture of the LT1081 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. Application includes portable computers, battery-powered RS232 systems, power supply generator, terminals, modems.

• Data rate is 120kBd min (RL = 3K, CL = 2500pF, TA = 25°C)
• Improved protection: outputs can be forced to ±30V without damage
• Three-state outputs are high impedance when off
• Only needs 1µF capacitors, absolutely no latchup
• CMOS comparable low power: 60mW
• Can power additional RS232 drivers: 10mA
• Supply current in shutdown: 1µA
• Slew rate is 15V/µs typ (RL = 3K, CL = 51pF, TA = 25°C)
• Output voltage is 0.2V typ (Output low, IOUT = -1.6mA, TA = 25°C)
• 16 lead PDIP package, operating temperature range from -40°C to 85°C
