Overview

Radiation hardened Low Voltage Technology (LVT) line dual 16-bit transceivers and level shifters in a highly miniaturized package, bring the maximum area and weight savings for Space applications board’s designs. Conceived for low power and very high speed applications. Performs cold sparing and bus hold function enabling a two-way asynchronous communication between buses (address, data). The direction of data transmission is determined by a digital input. The two enable inputs, can be used to disable the device cold-sparing the component to the bus. Enable inputs can be shorted together to provide 32-bit operation.

Devices are offered with standard SOP footprint for high resistance SMT assembly and for withstanding harsh thermal and mechanical environments.

LVT product line offers a wide range of supply voltages suitable for high reliability and all space applications such as commercial or scientific GEO stationary mission, Earth observation, navigation, manned space vehicles and deep space scientific exploration.
