LT1781CN#PBF General Description

Designed to comply with EIA RS232 standards, the LT1781CN#PBF features driver outputs that are safeguarded from overload, allowing for short circuits to ground or up to ±30V without risking damage. Moreover, during SHUTDOWN or power-off situations, both driver and receiver outputs transition into a high impedance state, facilitating seamless line sharing. With just 0.1µF external capacitors, this product delivers outstanding performance while minimizing external component requirements. Its robust design and ability to withstand harsh operating conditions make the LT1781CN#PBF an ideal choice for a wide range of industrial and communication applications
