Electrical & Optical Specifications

Specifications hold over 3.0 V ≤ VCC ≤ 5.5 V and 0°C ≤ TA ≤ 70°C and all typicals are at VCC = 5.0 V and

TA = 25°C unless otherwise specified. Listed conditions represent worst case values for the parameters

under test. Unspecified test conditions can be anywhere in their recommended operating range.

Conditions

For in-band EI ≥ 3.6 µ

W/cm2, ϕ1/2 ≤ 15°

Iο = -20 µA, for in-band EI

≤ 0.3 µW/cm2

Half-angle, ϕ1/2, is the

angle where receiver

sensitivity = 3.6 µW/cm2.

ILEDA = 240 mA, VI = 2.5 V

TA = 25°C

0°C ≤ TA ≤ 70°C

Half-angle, θ1/2, is the angle

where radiant intensity =

44 mW/SR.

0 ≤ VI ≤ 0.8 V

VI = 2.5 V

VI = 5.0 V

ILEDA = 240 mA,

Tj = 25°C

VLEDA = VCC = 5.5 V,

VI = 0.3 V

VCC = 3.6 V

VCC = 5.5 V,

EI = EIIL, VI (TXD) = VIL

VCC = 5.5 V,

EI = EIIH, VI(TXD) = VIL

VCC = 5.5 V,

EI = EIIL, VI(TXD) = VIH

VCC = 3.6 V

VCC = 5.5 V,

EI = EIIL, VI(TXD) = VIL,

VSD = VIH

VCC = 5.5 volts

VSD = 5.5 volts

VCC = 3.6 volts

VSD = 3.6 volts

3.0 V ≤ VCC ≤ 5.5 V

0 V ≤ VSD ≤ 0.8 V

Notes:

1. 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).

2. 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-1001.
