description

It is now obsolete from H (metal cans), J (ceramics) and K (metal cans) from linear technologysoftware package

® The LT 1280A/LT1281A integral charge pump dual RS232 driver/receiver pair generates the voltage level of RS232 for a single 5V supply. These circuits feature rugged bipolar designs, providing operating system fault tolerance and ESD protection unmatched by competing CMOS designs. Using only 0.1μF external capacitors, these circuits consume only 40mW of power and can operate 120kbaud even high capacitive loads while driving. The new ESD architecture on the chip allows the LT1280A/LT1281A to survive multiple ± 10kV hits, eliminating the need for expensive TransZorbs for RS232 line pins ®. The LT1280A/LT1281A are fully EIA RS232 compliant. The driver outputs overload protection and can be short-circuited to ground or up to ± 30V without damage. In the event of a shutdown or power-down condition, the driver and receiver outputs are in a high-impedance state, allowing line sharing.

The LT1281A is available in 16-lead DIP and SO packages. The LT1280A is available in 18-lead DIP and SO packages and the application needs to be closed.
