Photo Modules for PCM Remote Control Systems
Available types for different carrier frequencies
DescriptionThe TSOP21..UH1 – series are miniaturized receivers
for infrared remote control systems. PIN diode and
preamplifier are assembled on lead frame, the epoxy
package is designed as IR filter.
The demodulated output signal can directly be
decoded by a microprocessor. The main benefit is the
reliable function even in disturbed ambient and the
protection against uncontrolled output pulses.

Features Photo detector and preamplifier in one package Internal filter for PCM frequency Improved shielding against electrical field
disturbance TTL and CMOS compatibility Output active low Low power consumption High immunity against ambient light Enhanced data rate of 2400 bit/s Operation with short bursts possible
(≥6 cycles/burst)
