RHFLVDS32A:Rad-Hard quad LVDS receiver

The RHFLVDS32A is a quad, low-voltage differential signaling (LVDS) receiver specifically designed, packaged and qualified for use in aerospace environments in a low-power and fast data transmission standard.

The circuit features an internal fail-safe function to ensure a known state in case of an input short circuit or a 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 RHFLVDS32A achieves “best in the class” for hardness to total ionisation dose and heavy ions.

The RHFLVDS32A can operate over a large temperature range of -55 °C to +125 °C and it is housed in an hermetic Ceramic Flat-16 package.
