The Intersil HS-26C31RH, HS-26C31EH are quad differential line drivers designed for digital data transmission over balanced lines and meets the requirements of EIA standard RS-422. Radiation hardened CMOS processing assures low power consumption, high speed, and reliable operation in the most severe radiation environments.
The HS-26C31RH, HS-26C31EH accept CMOS levels and converts them to RS-422 compatible outputs. These circuits uses special outputs that enable the drivers to power-down without loading down the bus. Enable and disable pins allow several devices to be connected to the same data source and addressed independently.
