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.

1. All voltages, except differential I/O bus voltage, are with respect to the network ground terminal.
2. Short-circuits can cause excessive heating. Destructive dissipation can result from short-circuits on the
amplifiers.
