SN75174DW .

产品概述

The SN75174DW is a quadruple monolithic differential Line Driver with 3-state outputs. It is designed to meet the requirements of ANSI standards EIA/TIA-422-B and RS-485 and ITU recommendation V.11. It is optimized for balanced multipoint bus transmission at rates up to 4Mbps. Each driver features wide positive and negative common-mode output voltage ranges making it suitable for party-line applications in noisy environments. It provides positive- and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of approximately 150°C.
