Notes:
1. Pin numbers and resistor labels are per MMCA31A8574AA and MMCA11A8574AA descriptions.
2. Node labels are per L8574 package.
3. For 600 V power cross, resistor networks should “open” in less than 40 ms.

1. Continuous (RMS) power.
2. For 50 dB longitudinal balance; 0.2% for 58 dB balance.
Note: Fuses F1 and F2 provide fail-safe operation if excessive overvoltage conditions exist on Tip and Ring. They will not operate if the total
power dissipation of the entire resistor network is
