Note:

13. An in-band optical signal is a pulse/sequence where the peak wavelength,

λp, is defined as 850 nm ≤ λp ≤ 900 nm, and the pulse characteristics

are compliant with the IrDA Serial Infrared Physical Layer Link Specification.

Absolute Maximum Ratings

For implementation where case to ambient thermal resistance is

≤ 50˚C/W.
