DESCRIPTION
The TSOP312.., TSOP314.. 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 be directly decoded by
a microprocessor. The TSOP312.. is compatible with all
common IR remote control data formats. The TSOP314.. is
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.
