GENERAL DESCRIPTION
The HI-8436 is a 32-channel discrete-to-digital sensor fabricated with Silicon-on-Insulator (SOI) technology
designed to interface with a Serial Peripheral Interface (SPI).
Four banks of 8 sense inputs can be programmed as either GND/Open or Supply/Open sensors. Supply/Open
sensing is also referred to as 28V/Open sensing.
