RS485 Transceivers


Posted on Mar 26, 2013

Recent innovations in process and circuit design have enabled the release of three new RS485 transceivers: the LTC®1481, LTC1483 and LTC1487. These devices share an improved receiver circuit which features 80mA quiescent current operation (driver disabled) with no loss in AC performance relative to standard RS485 devices, and a new 1mA shutdown mode (Figure 1).



The LTC1481 provides full 2.5Mbaud driver and receiver speeds with the low power and improved ruggedness features shared by all three members of the family. Like all Linear Technology RS485 products, it features full RS485 and RS422 compatibility, gua
