Electrical Characteristics
Ring Trip Requirements
Table 11. Timing Requirements (DI, EN, DO, and RD), CCLK = 2.048 MHz
1. Unless otherwise specified, all times are measured from the 50% point of logic transitions.
2. This parameter is not tested in production. It is guaranteed by design and device characterization.

Ringing signal:
— Voltage, minimum 35 Vrms, maximum 100 Vrms.
— Frequency, 17 Hz to 28 Hz.
— Crest factor, 1.4 to 2.
Ringing trip:
— 100 ms (typical), 250 ms (V
Pretrip:
— The circuits in Figure 4 will not cause ringing trip.
