Electrical & Optical Specifications
Specifications hold over the Recommended Operating Conditions unless otherwise noted. Unspecified test conditions
can be anywhere in their operating range. All typical values are at 25 °C and 3.3 V unless otherwise noted.

Notes:
7. Logic Low is a pulsed response. The condition is maintained for duration dependent on pattern and strength of the incident intensity.
8. An in-band optical signal is a pulse/sequence where the peak wavelength, lp, is defined as 850 ≤ lp ≤ 900 nm, and the pulse characteristics are
compliant with the IrDA Serial Infrared Physical Layer Link Specification.
9. For in-band signals ≤ 115.2 kb/s where 3.6 µW/cm2 ≤ EI ≤ 500 mW/cm2.
10. Wake Up Time is the time between the transition from a shutdown state to an active state and the time when the receiver is active and ready
to receive infrared signals.
