Overview
December 2013 HI-8420, HI-8423 6-Channel / 8-Channel Discrete-to-Digital Interface Sensing Open / Ground Signals DESCRIPTION The HI-8420 is a six channel discrete-to-digital interface device.
The HI-8423 has eight channels.
Mixed-signal CMOS technology is used to provide superior low-power performance.
The device inputs are configured to sense Ground / Open discrete signals.
The device outputs are CMOS / TTL compatible and may be disabled (tri-state) using the CE and OE pins.
The HI-8420 is a drop-in replacement for the DEI1026.
For added functionality, the Holt HI-8422 offers eight channels of Open / Ground sensing and eight channels of 28V / Ground sensing in a single device.
