D*CRIPTION
The TSOP341.., TSOP343.. series are miniaturized
receivers for infrared remote control systems. A PIN diode
and a preamplifier are *embled on a lead frame, the epoxy
package acts as an IR filter.
The demodulated output signal can be directly decoded by a
microprocessor. The TSOP341.. is compatible with all
common IR remote control data formats. The TSOP343.. is
optimized to better suppress spurious pulses from energy
saving fluorescent lamps but will also suppress some data
signals.
This component has not been qualified according to
automotive specifications.
