Description

  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.
