Description

General part information

ISOS141-SEP Series

The ISOS141-SEP radiation-tolerant device is a high-performance, quad-channel digital isolator in a small form factor 16-pin QSOP package. Each isolation channel has a logic input and output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. This device supports low Earth orbit (LEO) space applications with its high data rate of 100 Mbps, low propagation delay of 10.7 ns, and tight channel-to-channel skew of 4 ns. The ISOS141-SEP device has three forward and one reverse-direction channels and if the input power or signal is lost, the default output is low. The enable pins can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption.

The ISOS141-SEP provides high electromagnetic immunity and low emissions with low power consumption, while isolating CMOS or LVCMOS digital I/Os. The device has a high common-mode transient immunity of 100 kV/µs and can ease system-level ESD, EFT, surge, and simplify emissions compliance through its innovative chip design.
