Additional Details

The HS0038A series typically operates at a carrier frequency of 38 kHz. The supply voltage range is typically 2.7 V to 5.5 V, and the supply current is typically less than 1 mA. The output is an active low signal. Different models within the HS0038A series may have slightly different specifications, so it's important to consult the datasheet for the specific model being used. The device is often packaged in a three-pin epoxy package.
