RHFLVDS31A：Rad-Hard quad LVDS driver

The RHFLVDS31A is a quad, low-voltage, differential signaling (LVDS) driver specifically designed, packaged, and qualified for use in aerospace environments in a low-power and fast point-to-point baseband data transmission standard.

Operating at 3.3 V power supply, the RHFLVDS31A 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 floating input. All pins have cold spare buffers to ensure they are in high impedance when VCC is tied to GND.

Designed on ST's proprietary CMOS process with specific mitigation techniques, the RHFLVDS31A achieves “best in the class” for hardness to total ionisation dose and heavy ions.

The RHFLVDS31A can operate over a large temperature range of -55 °C to +125 °C and it is housed in an hermetic Ceramic Flat-16 package.
