STMicroelectronics has strengthened its space-grade semiconductor portfolio with the RHFLVDS42, a QML-V-qualified quad low-voltage differential signaling (LVDS) receiver designed for high-speed data transmission in aerospace and space applications. The device supports data rates of up to 600 Mbps while combining low power consumption, radiation resistance, and enhanced electrostatic discharge (ESD) protection.
The RHFLVDS42 operates across a supply voltage range of 2.3V to 3.6V and complies with the TIA/EIA-644 standard, along with applicable JEDEC low-voltage logic and power-supply requirements. It also supports legacy CMOS designs, allowing integration into existing electronic systems. Its input common-mode voltage range of -4V to +5V helps ensure reliable signal reception in electrically noisy environments, while an absolute maximum voltage rating of 4.8V enhances its ability to withstand power-supply transients.
Designed for harsh radiation environments, the receiver offers robust protection against several radiation-induced effects. STMicroelectronics reports single-event latch-up (SEL)-free operation at a linear energy transfer (LET) of 122.6 MeV·cm²/mg, along with single-event transient (SET)- and single-event upset (SEU)-free performance at 61.3 MeV·cm²/mg. The device meets Radiation Hardness Assurance (RHA) QML-V requirements for total ionizing doses of up to 300 krad (Si). It also delivers ESD immunity of up to 8kV.
Manufacturing takes place at STMicroelectronics’ facility in Rennes, France, using 130nm CMOS technology that the company has employed in space applications for more than a decade. The RHFLVDS42 carries an EAR99 export classification, which can help facilitate international supply-chain operations, including shipments involving the United States and Asian markets.
The receiver supports an operating temperature range of -55°C to +125°C and comes in a hermetic Flat-16 package with a grounded lid. Its flow-through pin configuration is designed to minimize crosstalk and simplify printed circuit board (PCB) layout. For applications with stringent size and weight requirements, STMicroelectronics also provides a bare-die version.
The RHFLVDS42 is intended for aerospace and space systems requiring high-speed differential signaling, radiation resilience, and dependable operation under demanding environmental conditions. Its combination of compact packaging, low power consumption, and radiation-qualified performance makes it suitable for applications where reliability and efficient system integration are essential.
