LT1039 - RS232 Driver/Receiver with Shutdown - Linear Technology（凌力尔特）

功能描述

The LT?1039 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. Bipolar circuitry makes this driver/receiver exceptionally rugged against overloads and immune to latchup.

A BIAS pin allows one receiver to be kept on while the rest of the part is shut down.

The LT1039 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 LT1080/LT1081, LT1180A/LT1181A andLT1130A data sheets. For applications requiring 15kV ESD, see the LT1039A.
