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.
