LT1080/LT1081
10801fe
Advanced Low Power
5V RS232 Dual Driver/Receiver
The LT
1080/LT1081 are the only dual RS232 driver/
receiver with charge pump to guarantee absolutely no
latchup. These interface optimized devices provide a real-
istic 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 LT1080/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.
For applications requiring up to five drivers and five
receivers with charge pump in one package see the LT1130A
Series data sheet. A version of the LT1080/LT1081, the
LT1180A and LT1181A that use only 0.1
F capacitors, is
also available. All of Linear Technology’s RS232 ICs are
available in standard surface mount packages.
