描述 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.
