DescripTion
Triple RS232 Driver/Receiver
with Shutdown
The LTC1039A is a triple RS232 driver/receiver that
includes shutdown. Each receiver will accept up to ±30V
input and can drive either TTL or CMOS logic. The RS232
drivers accept TTL logic inputs and output RS232 voltage
levels.Theoutputsarefullyprotectedagainstoverloadand
can be shorted to ground or up to ±30V without damage
to the drivers. Additionally, when the system is shut down
or power is off, the outputs are in a high impedance state
allowing data line sharing. On-chip ESD protection elimi-
nates the need for external protection devices.
A bias pin allows one receiver to be kept on while the rest
of the part is shut down.
TheLT1039Aisalsoavailableinthe16-pinversion,without
shutdown or bias pin functions.
For applications requiring operation from a single 5V
supply, see the LT1180A/LT1181A and LT1130A data
sheets.
