HI-8422 - 16-Channel Discrete-to-Digital Interface

Description

The HI-8422 is a sixteen channel discrete-to-digital interface device.

The device has eight channels designed to sense 28 V / Open signals and eight channels that sense Open / Ground signals.

Data is multiplexed from each bank of sensors to an eight bit digital databus.

Features

  • ! 8 independent 28 Volt / Open sensing channels ! 8 independent Open / Ground sensing channels ! 5.0 V single supply operation ! Low power CMOS technology ! Industrial and Extended temperature ranges PIN.

September 2014 HI-8422 16-Channel Discrete-to-Digital Interface Sensing 28 Volt / Open and Open / Ground Signals DESCRIPTION The HI-8422 is a sixteen channel discrete-to-digital interface device. The device has eight channels designed to sense 28 V / Open signals and eight channels that sense Open / Ground signals. Data is multiplexed from each bank of sensors to an eight bit digital databus. Mixed-signal CMOS technology is used to provide superior low-power performance. The device outputs are CMOS / TTL compatible and may be disabled (tri-state) using the CE and OE pins. The HI-8422 is offered in a small footprint 32-pin Plastic Quad Flat Package (PQFP). Please contact the Holt sales department for other packaging options.
