The HI-8424 is an eight channel discrete-to-digital device. Mixed-signal CMOS technology is used to provide superior low-power performance. The device has eight separate 28V/Open sensing inputs with CMOS/TTL compatible outputs that can be disabled (tri-state) using the /CE and /OE pins. The HI-8424 is offered in a small footprint 20-pin plastic TSSOP package.
