LT1039A/LT1039A-16
Triple RS232 Driver/Receiver
with Shutdown
DESCRIPTIO
N
U
The LT
1039A 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. The outputs are fully protected against overload
and 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 eliminates 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.
The LT1039A is also available in the 16-pin version,
without shutdown or bias pin functions.
For applications requiring operation from a single 5V
supply, see the LT1180A/LT1181A and LT1130A data
sheets.
