EI = In-Band Infrared Intensity at detector

Notes:

1. In-Band El ≤ 115.2 kb/s.

2. Logic Low is a pulsed response. The condition is maintained for duration dependent on the pattern and strength of the incident intensity.

3. To maintain low shutdown current, TXD needs to be driven high or low and not left floating.
