Electrical & Optical Specifications

Specifications hold over the Recommended Operating Conditions unless otherwise noted. Test Conditions represent worse case

values for the parameters under test. Unspecified test condition can be anywhere in their recommended operating range. All typicals

are at 25°C and 5V unless otherwise noted.

Notes:

1. EI – received in band light intensity present at detector surface.

2. Pulsed Response – Logic Low is a pulsed response. A receiver output low state VOL (RXD) is not indefinitely maintained but is instead a

pulsed response. The output low state is maintained for a duration dependent on the incident bit pattern and

incident intensity (EI).

3. The EI ≥ 3.6 µW/cm2 condition guarantees the IrDA minimum receiver sensitivity of 4.0 µW/cm2 while allowing for 10% light loss

through a cosmetic window placed in front of the HSDL-1000. (See the Rx TH+ section at the end of this data sheet for information

on receiver sensitivity over temperature, and in the presence of ambient light.)
