RHFLVDSR2D2：Rad-Hard dual LVDS transceiver

Dual low voltage differential signaling (LVDS), driver receiver designed, packaged and qualified for use in aerospace environments in a low-power and fast-transmission standard, and operating at 3.3 V power supply (3.6 V max operating and 4.8 V AMR). The RHFLVDSR2D2 operates over a controlled impedance of 100-ohm transmission media that may be printed circuit board traces, back planes, or cables.

The circuit features an internal fail-safe function to ensure a known state in case of an input short circuit or floating input. All pins have cold spare buffers to ensure they are in high impedance when VCC is tied to GND.

The RHFLVDSR2D2 can operate over a large temperature range of -55 °C to +125 °C and it is housed in an hermetic Ceramic Flat-18 package.
