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.
Please see the document “Product Transition Schedule” at

SUITABLE DATA FORMAT
The TSOP312.., TSOP314.. series are designed to suppress
spurious output pulses due to noise or disturbance signals.
Data and disturbance signals can be distinguished by the
devices according to carrier frequency, burst length and
envelope duty cycle. The data signal should be close to the
band-pass center frequency (e.g. 38 kHz) and fulfill the
conditions in the table below.
When a data signal is applied to the TSOP312.., TSOP314..
in the presence of a disturbance signal, the sensitivity of the
receiver is reduced to insure that no spurious pulses are
present at the output. Some examples of disturbance
signals which are suppressed are:
• DC light (e.g. from tungsten bulb or sunlight)
• Continuous signals at 38 kHz or at any frequency
• Strongly or weakly modulated noise from fluorescent
lamps with electronic ballasts (see figure 15 or figure 16)
