LT1081ISW

Advanced low-power 5V RS232 dual driver/receiver

peculiarity Speed increase over CMOS: Works 120kBaud Perfect protection: the output can force ± 30V There is absolutely no lockdown CMOS comparatively low power: 60MW Power Additional RS232 Driver: 10 mAh Shutdown: 1μA supply current Available in SO packages With or without shutdown ® The LT 1080/LT1081 is the only dual RS232 driver/receiver with charge pump to guarantee absolute no latching. These real-world requirements to optimize the power consumption and durability of CMOS levels between device interfaces provide a realistic balance. The fully protected driver outputs are overloaded and short-circuited to ± 30V. Different CMOS, advanced architecture LT1080/LT1081 does not load signal lines when "off" or when power is lost. receiver and RS232 output high impedance state input. Advanced output stages enable higher speeds, more robust public service electronic programming, and drive high-capacitance loads. For those who require 5 drivers and a pack of 5 receivers with charge pumps LT1130A series datasheet. Versions of the LT1080/LT1081, LT1180A and LT1181A using only 0.1μF capacitors are also available. Linear RS232 chips are available in standard surface-mount packages.
