LT1081ISW Description

Short technical summary and product information.

The LT1081ISW is an advanced, low-power dual RS232 driver and receiver IC from Linear Technology. It features a charge pump design that guarantees no latchup and provides a balance between CMOS power dissipation and real-world ruggedness.

 

Key electrical specifications include operation over 120kBaud data rates and low power consumption of typically 60mW. The driver outputs are protected against overload and can be shorted to –30V without damage. Unlike CMOS devices, the LT1081ISW's outputs enter a high-impedance state when shut down or when power is off, preventing signal line loading.

 

This device is suitable for applications such as portable computers, battery-powered RS232 systems, and modems. It requires only 1µF capacitors for its charge pump. The LT1081ISW is available in an SO package for surface mounting.

 

It offers superior performance compared to CMOS alternatives, with improved speed and protection. The device also features three-state outputs that are high impedance when off, and it only needs 1µF capacitors for operation.
