The LT1039CSW is a versatile triple RS232 driver/receiver integrated circuit manufactured by Linear Technology. This component is designed to meet RS232 specifications and includes a shutdown feature, allowing for power saving when not in use. Each receiver can accept input voltages up to -30V and drive TTL or CMOS logic, while the drivers accept TTL logic inputs and output RS232 voltage levels.
The drivers are fully protected against overload conditions and can be shorted to ground or up to -30V without sustaining damage. When the system is shut down or power is off, the outputs enter a high impedance state, facilitating data line sharing. The bipolar circuitry ensures ruggedness against overloads and immunity to latch-up. A BIAS pin is available on some versions to keep one receiver active while the rest of the part is shut down.
This device operates from supply voltages ranging from -5V to -15V. The LT1039CSW is available in an 18-lead SOIC package, suitable for surface mounting. Its robust design and comprehensive features make it suitable for various RS232 interface applications, including terminals and modems.
