Product overview
Description
The LEOLVDSRD is a 3 V to 3.6 V power supply (4.8 V absolute maximum ratings) low voltage differential signaling (LVDS) driver and receiver qualified for use in aerospace environments. It 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 an input short-circuit or floating input. All pins have cold spare buffers to ensure they are in high impedance when VCC is tied to GND.
The LEOLVDSRD can operate over a large temperature range of -40 °C to +125 °C and it is housed in plastic TSSOP-20, thin-shrink small outline package, 20 leads, using gold-wires and nickel/palladium/golden-lead-finishing to prevent from whiskers.
The LEOLVDSRD is compliant with ST-LEO-specification, dedicated specification for space-ready rad-hard plastic products. This AEC-Q100-based specification offers a specific trade-off among footprint size savings, cost of ownership and quality assurance together with radiation hardness and a large quantity capability.
