The HS-26CLV31RH and HS-26CLV31EH are radiation hardened 3. 3V quad differential line drivers designed for digital data transmission over balanced lines, in low voltage RS-422 protocol applications. CMOS processing assures low power consumption, High-Speed, and reliable operation in the most severe radiation environments. The HS-26CLV31RH and HS-26CLV31EH accept CMOS level inputs and converts them to differential outputs. Enable pins allow several devices to be connected to the same data source and addressed independently. These devices have unique outputs that become high impedance when the driver is disabled or powered-down, maintaining signal integrity in multi-driver applications.
