DESCRIPTION
MECHNICAL DATA
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.
Pinning for TSOP348.., TSOP344..:
1 = OUT, 2 = GND, 3 = VS
Pinning for TSOP322.., TSOP324..:
1 = OUT, 2 = VS, 3 = GND
The demodulated output signal can be directly decoded
by a microprocessor. The TSOP348.., TSOP322.. are
compatible with all common IR remote control data formats.
The TSOP324.., TSOP344.. are optimized to suppress
almost all spurious pulses from energy saving fluorescent
lamps but will also suppress some data signals.
Please see the document “Product Transition Schedule” at
www.vishay.com/ir-receiver-modules/ for up-to-date info,
when this product will be released.
This component has not been qualified according to
automotive specifications.
