SN75ALS1178 - Dual Differential Drivers and Receivers

Download the SN75ALS1178 datasheet PDF. This datasheet also covers the SN75ALS1177 variant, as both devices belong to the same dual differential drivers and receivers family and are provided as variant models within a single manufacturer datasheet.

General Description

The SN75ALS1177 and SN75ALS1178 dual differential drivers and receivers are integrated circuits designed for bidirectional data communication on multipoint bus transmission lines.

The devices are designed for balanced transmission lines, and meet standards TIA/EIA-422-B and TIA/EIA-485-A.

Key Features

  • Meet or exceed standards TIA/EIA-422-B and TIA/EIA-485-A.
  • Designed for multipoint bus transmission on long bus lines in noisy environments.
  • Low supply-current requirement 50mA maximum.
  • Driver positive-and negative-current limiting.
  • Driver common-mode output voltage range of.
  • 7V to 12V.
  • Thermal shutdown protection driver 3-state outputs active-high enable.
  • Receiver common-mode input voltage range of.
  • 12V to 12V.
