Product Summary
The LT1281ACN is a dual RS232 driver/receiver pairs with integral charge pump to generate RS232 voltage levels from a single 5V supply. New ESD structures on the chip allow the LT1281ACN to survive multiple ±10kV strikes, eliminating the need for costly TransZorbs on the RS232 line pins. The LT1281ACN is fully compliant with EIA RS232 standards. Driver outputs are protected from overload, and can be shorted to ground or up to ±30V without damage. It is available in 16-pin DIP and SO packages. During shutdown or power-off conditions, driver and receiver outputs are in a high impedance state, allowing line sharing. The applications of the LT1281ACN are Portable Computers, Battery-Powered Systems, Power Supply Generator, Terminals, Modems.
