ISOS141FDBQSEP General Description

The ISOS141-SEP digital isolator is a cutting-edge solution for space applications, offering high performance and reliability in a compact 16-pin QSOP package. With a data rate of 100 Mbps and a low propagation delay of 10.7 ns, this device is ideal for low Earth orbit (LEO) missions. Its tight channel-to-channel skew of 4 ns ensures precise synchronization between input and output signals, while the three forward and one reverse-direction channels provide versatile functionality

Key Features

Fast cooling technology
Precise temperature control
Easy-clean exterior
Durable construction
