| | Possible Cause | Solution | | :--- | :--- | :--- | | Component not found | Library file not installed correctly or placed in the wrong folder. | Re-download the library, ensure it's placed in the correct LIBRARY folder, and restart Proteus. | | No output signal | Power supply not connected to the receiver (VCC pin). | Double-check that the VCC pin is connected to a +5V source and GND to ground. | | | Transmitter not generating a 38 kHz modulated signal. | Verify the frequency of your IR LED driver circuit or PWM signal. | | Output stuck low | Transmitter is continuously sending a signal. | Modify your transmitter code or circuit to send bursts of data rather than a continuous stream. | | | The IR LED and receiver are not aligned in the schematic. | Ensure the IR LED is facing the receiver in the workspace. | | Simulation crash | Model file (.DLL or .HEX) is missing or corrupt. | Re-install the library, ensuring that all model files are placed in the MODELS folder. |
Navigate to your Proteus installation directory. It is usually found at: tsop1738 proteus library download

: Avoid downloading unprotected library files. Instead, follow Section 4. | Double-check that the VCC pin is connected
The TSOP1738 is a miniaturized receiver for infrared remote control systems. It combines a PIN diode, preamplifier, and bandpass filter into a single three-pin package. Key Specifications 38 kHz (matches standard TV remotes) Operating Voltage: 5V (TTL and CMOS compatible) Low Power Consumption: Minimal current draw Demodulated Output: Active low signal output Why Do You Need a Custom Proteus Library?
It responds to a specific infrared carrier frequency of 38 kHz .
