Description
The RHFLVDS325 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 using ST's proprietary CMOS process with specific mitigation techniques, the RHFLVDS325 achieves “best in the class” for hardness to total ionisation dose and heavy ions.
The RHFLVDS325 can operate over a large temperature range of -55 °C to +125 °C and is housed in a hermetic Ceramic Flat-16 package.
