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 V
(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

condition guarantees the IrDA minimum receiver sensitivity of 4.0

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.)
