DESCRIPTION
The TSOP312.., TSOP314..series are miniaturized IR
receiver modules for infrared remote control systems. A PIN
diode and a preamplifier are assembled on a leadframe, the
epoxy package contains an IR filter.
The demodulated output signal can be directly connected to
a microprocessor for decoding.
The TSOP312.., TSOP314.. are optimized to suppress
almost all spurious pulses from energy saving lamps like
CFLs. The AGC4 used in the TSOP314.. may suppress
some data signals. The TSOP312.. is a legacy product for
all common IR remote control data formats. Between these
two receiver types, the TSOP314.. is preferred. Customers
should initially try the TSOP314.. in their design.
These components have not been qualified according to
automotive specifications.
Note
(1) We advise try AGC4 first if the burst length is unknown.

Note
• Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only
and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating conditions for extended periods may affect the device reliability.
