TSOP75338TR

TSOP75338TR is a 38 kHz infrared receiver module. It contains a photodiode, low-noise preamp, automatic gain control, a 38 kHz band-pass filter, and a demodulator, delivering a clean digital output that represents received remote-control data. It operates from about 2.7–5.5 V and has three pins: GND, Vcc, and OUT. The output is active-low (low during a valid IR burst). It rejects ambient light and handles typical 38 kHz remote protocols (e.g., NEC, RC5, RC6). The “TR” suffix usually denotes Tape & Reel packaging for automated assembly. Common uses include TV/DVD/AV remotes, set-top boxes, and other consumer electronics. For best performance, place a decoupling capacitor near Vcc and connect the output to a microcontroller input with appropriate logic levels.
