TSOP44..RF1

Vishay Semiconductors

IR Receiver Modules for Remote Control Systems

Description

The TSOP44..RF1 - 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.
