MECHANICAL DATA
Pinning for TSOP44.., TSOP48..:
DESCRIPTION
These products 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.
1 = OUT, 2 = GND, 3 = VS
Pinning for TSOP22.., TSOP24..:
1 = OUT, 2 = VS, 3 = GND
The demodulated output signal can be directly decoded by
a microprocessor. The TSOP22.., TSOP48.. are compatible
with all common IR remote control data formats. The
TSOP24.., TSOP44.. are optimized to suppress almost all
spurious pulses from energy saving fluorescent lamps but
will also suppress some data signals.
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.
