LT1039CSW#PBF

LT1039 is a triple RS232 driver/receiver that includes shutdown. Each receiver will accept upto ±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 upto ±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 latch up. A BIAS pin allows one receiver to be kept on while the rest of the part is shut down. It is widely used in application such as RS232 interface, terminals, modems etc.
