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 and 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.
