HI-8435PQTF Description

Short technical summary and product information.

The HI-8435PQTF is a 32-channel discrete-to-digital sensor designed for avionics applications. It operates at 3.3V and communicates via a 20MHz Serial Peripheral Interface (SPI). The device offers robust performance due to its Silicon-on-Insulator (SOI) technology, ensuring latch-up-free operation.

The sensor features programmable input thresholds and hysteresis, adjustable in 0.5V steps from 2V to 21V. The 32 sensing channels are divided into four banks of eight, each independently configurable to detect either GND/Open or 28V/Open signals. All sense inputs are internally lightning protected to DO160G standards without requiring external components.

The HI-8435PQTF is available in industrial (-40°C to +85°C) and extended (-55°C to +125°C) temperature ranges. It comes in multiple standard package options, including the 44-pin PQFP and a compact 7mm x 7mm 44-pin QFN. The device is fully compliant with Airbus ABD0100H standards.
