SN65HVD1176DRG4

RS-485接口IC PROFIBUS RS-485 Transceiver

Description

The SNx5HVD1176 devices are half-duplex differential transceivers with characteristics optimized for use in PROFIBUS EN 50170 applications. The driver output differential voltage exceeds the PROFIBUS requirements of 2.1 V with a 54-Ω load. A signaling rate of up to 40 Mbps allows technology growth to high data-transfer speeds. The low bus capacitance provides low signal distortion.
