描述 Description

The HI-8435 is a 3.3V, 32-channel discrete-to-digital sensor with Serial Peripheral Interface (SPI) and built-in lightning protection. The device is fabricated with Silicon-on-Insulator (SOI) technology?for robust latch-up free operation.?The sense input thresholds and hysteresis are programmable via the 20MHz SPI bus and all 32 sense output states may be read with a single SPI command. The device is also fully compliant to Airbus ABD0100H.?
The 32 sensing channels are divided into 4 banks of 8 inputs, with each bank configurable over the SPI bus to detect either GND/Open or 28V/Open signals. Thresholds and hysteresis are programmable in 0.5V steps from 2V to 21V, with GND/Open and 28V/Open input banks independently configurable.?
All sense inputs are internally lightning protected to DO160G, Section 22, Cat AZ, BZ and ZZ without external components.
The device is available in industrial ?40oC to +85oC and extended ?55oC to +125oC temperature ranges and comes in multiple standard package options, including 44 pin PQFP and compact 7mm x 7mm 44-pin QFN.
