December 2013 HI-8421, HI-8424 6-Channel / 8-Channel Discrete-to-Digital Interface Sensing 28V / Open Signals DESCRIPTION The HI-8421 is a six channel discrete-to-digital interface device.The HI-8424 has eight channels. Mixed-signal CMOS technology is used to provide superior low-power performance. The device inputs are configured to sense 28V / Open discrete signals. The device outputs are CMOS / TTL compatible and may be disabled (tri-state) using the CE and OE pins. The HI-8421 is a drop-in replacement for the DEI1054. 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.
