DESCRIPTION
1 = OUT, 2 = GND, 3 = VS
The TSOP41.., TSOP43.. 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 TSOP41.. is the
compatibility to all IR remote control data formats. The
TSOP43.. is optimized to better suppress spurious pulses
from fluorescent lamps, LCD TVs or plasma displays.
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.
