These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operation sections of the specifications is not implied. Exposure to Absolute Maximum Rat- ing conditions for extended periods may affect device reliability. TC7106/A AND TC7107/A ELECTRICAL SPECIFICATIONS Electrical Characteristics: Unless otherwise noted, specifications apply to both the TC7106/TC7106A and TC7107/TC7107A at TA = +25°C, fCLOCK = 48 kHz. Parts are tested in the circuit of the Typical Operating Circuit.
