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

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.
