LT1039MJ Description

Short technical summary and product information.

The LT1039MJ is a versatile triple RS232 driver/receiver IC manufactured by Analog Devices / Maxim Integrated. This component includes a shutdown feature, allowing for power saving when not in use. Each receiver can accept inputs up to -30V and drive TTL or CMOS logic, while the RS232 drivers accept TTL logic inputs and output RS232 voltage levels.

The outputs are fully protected against overload and can withstand short circuits to ground or up to -30V without damage. When the system is shut down or power is off, the outputs enter a high impedance state, enabling data line sharing. The bipolar circuitry ensures ruggedness against overloads and immunity to latch-up.

Key electrical specifications include an input voltage range of -30V, an input impedance of 30kΩ, and operation from -5V to -15V supplies. The LT1039MJ meets all RS232 specifications and is available in a 16-lead plastic small outline (SW) package, suitable for surface mounting.

This driver/receiver is ideal for applications such as RS232 interfaces, terminals, and modems where robust and reliable serial communication is required.
