HI-8436PQI Description

Short technical summary and product information.

The HI-8436PQI is a 32-channel discrete-to-digital sensor from Holt Integrated Circuits Inc., built with robust Silicon-on-Insulator (SOI) technology. Designed for avionics discrete sensing applications, it interfaces with microcontrollers and FPGAs via a 20MHz Serial Peripheral Interface (SPI) with 3.3V logic compatibility.

This sensor offers selectable sense operations, programmable for either GND/Open or 28V/Open inputs. The sensing circuit's window comparator thresholds can be programmed from 0.4V to 5.2V in 0.1V steps, with adjustable hysteresis. All 32 sense inputs are internally lightning protected to DO-160G, Section 22, Cat AZ, BZ, and ZZ without requiring external components.

The HI-8436PQI operates from a single low voltage supply and supports logic operation from 3.0V to 3.6V. It includes an internal self-test feature for added reliability. The part is available in a 44-pin Plastic Quad Flat Pack (MQFP) or Chip-Scale Package (QFN) with industrial and extended temperature ranges.

Available in industrial (-40°C to +85°C) and extended (-55°C to +125°C) temperature ranges, the HI-8436PQI is suitable for demanding environments. Its internal lightning protection and selectable sensing modes make it a versatile solution for avionics discrete sensing.
