DESCRIPTION
The TSOP77... series are miniaturized SMD IR receiver
modules for infrared remote control systems. Two PIN
diodes 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 TSOP774.. series devices are optimized to suppress
almost all spurious pulses from Wi-Fi and CFL sources.
They may suppress some data signals if continuously
transmitted.
The TSOP772.. series devices are provided primarily for
compatibility with old AGC2 designs. New designs should
prefer the TSOP774.. series containing the newer AGC4.
These components have not been qualified according to
automotive specifications.

SUITABLE DATA FORMAT
This series is designed to suppress spurious output pulses
due to noise or disturbance signals. The devices can
distinguish data signals from noise due to differences in
frequency, burst length, and envelope duty cycle. The data
signal should be close to the device’s band-pass center
frequency (e.g. 38 kHz) and fulfill the conditions in the table
below.
When a data signal is applied to the product in the presence
of a disturbance, the sensitivity of the receiver is
automatically reduced by the AGC to insure that no spurious
pulses are present at the receiver’s output.
Some examples which are suppressed are:
• DC light (e.g. from tungsten bulbs sunlight)
• Continuous signals at any frequency
• Strongly or weakly modulated noise from fluorescent
lamps with electronic ballasts (see Fig. 13 or Fig. 14)
• 2.4 GHz and 5 GHz Wi-Fi
