The HI-8421 is a six channel discrete-to-digital device. Mixed-signal CMOS technology is used to provide superior low-power performance. The device has six separate 28V/Open sensing inputs with CMOS/TTL compatible outputs that can be disabled (tri-state) using the /CE and /OE pins. The HI-8421 is a drop-in replacement for the DEI1054 and is offered in a small footprint 16-pin plastic SOIC package.
