NOTES:
3. These parameters are controlled via design or process parameters and are not directly tested. These parameters are characterized upon initial
design release and upon design changes which would affect these characteristics.
4. Differential Ringing Gain is measured with VRS = 0.795VRMS for -100V devices, VRS = 0.663 VRMS for -85V devices and VRS = 0.575VRMS
for -75V devices.
5. Longitudinal Balance is tested per IEEE455-1985, with 368Ω per Tip and Ring terminal.
6. These parameters are tested 100% at room temperature. These parameters are guaranteed not tested across temperature via statistical
characterization and design.
7. The power dissipation is based on actual device measurements and will be less than worst case calculations based on data sheet supply current
limits.
8. Characterized with 2 x 10µs, and 10 x 1000µs first level lightning surge waveforms (GR-1089-CORE)
9. For Unbalanced Ringing the Tip terminal is offset to 0V and the Ring terminal is centered at Vbh/2 + 0.5V.
