Figure 5: Copper Separation and Signal Traces for a Polyphase PCB
3.5 Compatibility with the 71M654x
The 71M6xxx isolated sensor ICs are designed to be operated in conjunction with the 71M654x energy-
metering ICs. Operation of the 71M6xxx isolated sensor ICs requires a 71M654x IC with CE code
capable of interfacing with the 71M6xxx. CE codes written for operation with CTs do not work with the
71M6xxx.
The 71M6xxx isolated sensor ICs are not arbitrarily interchangeable. Each type of the 71M6xxx must be
matched with its corresponding CE code in the 71M654x per Table 14. A 71M6xxx remote sensor IC
generates unpredictable results when paired with a CE code for a different part number. All 71M6xxx
isolated sensor ICs used in a polyphase system must be of the same part number.

4.1 Absolute Maximum Ratings
Table 3 shows the absolute maximum ranges for the device. Stresses beyond Absolute Maximum
Ratings may cause permanent damage to the device. These are stress ratings only and functional
operation at these or any other conditions beyond those indicated under recommended operating
conditions (4.3 Recommended Operating Conditions) is not implied. Exposure to absolute maximum
ratings conditions for extended periods may affect device reliability. All voltages are with respect to GND.
