DESCRIPTION
The TSOP581.. series are miniaturized receivers for infrared
remote control systems. A PIN diode and a preamplifier are
assembled on a lead frame, the epoxy package acts as an IR
filter.
The demodulated output signal can directly be decoded by a
microprocessor. The main benefit of the TSOP581.. is the
compatibility to all IR remote control data formats.
This component has not been qualified according to
automotive specifications.

The output voltage VO should not be pulled down to a level
below 1 V by the external circuit.
The capacitive load at the output should be less than 2 nF.
