Evaluation Board User Guide
Description
The
ISL71831SEH
is a radiation tolerant, 32-channel high ESD
protected multiplexer that is fabricated using Intersil's
proprietary P6SOI (Silicon On Insulator) process technology to
provide excellent reliability. It operates with a single supply
voltage ranging from 3.0V to 5.5V. This evaluation board is
designed to provide easy access to the capabilities of the part.
The evaluation board has a DIP switch, which provides a
convenient way to address all 32 channels without the need
for extra supplies. There's also a BNC input available that will
allow you to drive the address pins with a signal generator.
