n Available in SO Package The LTCВ®1039A is a triple RS232 driver/receiver that
includes shutdown. Each receiver will accept up to В±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 В±30V without damage
to the drivers. Additionally, when the system is shut down …
