The HI-84201 is a six channel discrete-to-digital interface device with inputs configured to sense Open / Ground discrete signals. All sense inputs are internally lightning protected to RTCA/DO160G, Section 22 Level 3 Pin Injection Test Waveform Set A (3 & 4), Set B (3 & 5A) and Set Z (3 & 5B) without using external components. The device outputs are CMOS / TTL compatible and may be disabled (tri-state) using the /CE and /OE pins.

The HI-84201 is a drop-in replacement for the DEI1026A and is offered in a small footprint 16-pin plastic SOIC package.
