Description
The RHFLVDS315 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
RHFLVDS315 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 using ST's proprietary CMOS process
with specific mitigation techniques, the
RHFLVDS315 achieves “best in the class” for
hardness to total ionisation dose and heavy ions.
The RHFLVDS315 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.
