General Description

The HT6740 is an RF transponder IC with 13.56MHz RF carrier, which provides a low cost batteryless tran sponder solution when combined with an external in ductor. The inductor and internal capacitor form an LC tank which induce voltage from the radiated 13.56MHz carrier signal generated from the reader antenna.
