HI-8470
16-Channel Discrete-to-Digital Sensor with ARINC 429 Transmitter
DESCRIPTION
The HI-8470 is a sixteen channel discrete-to-digital interface device. The IC has 16 channels which can sense Open/Ground or 28V/Open signal levels. The voltage threshold of the sensors is user programmable with external resistors. Sense input thresholds may also be set to CMOS logic levels to interface the part with other sensors, for example an external ADC or resolver.
An on-chip ARINC 429 transmitter / line driver allows the status of discrete lines to be transmitted in ARINC 429 format with pin-programmed label byte value, repetition rate and transmission speed.
