NOTES:

T = +25°C.

8. The HC55183 and HC55184 devices are specified with a single high battery voltage grade.

9. The device represents a low output impedance during ringing. Therefore the voltage across the ringing load is determined by the voltage divider

formed by the protection resistance, loop resistance and ringing load impedance.

10. The HC55183 and HC55184 are specified with a single longitudinal balance grade.

11. Longitudinal Balance is tested per IEEE455-1985, with 368

 per Tip and Ring Terminal.

12. These parameters are tested 100% at room temperature. These parameters are guaranteed not tested across temperature via statistical

characterization.

13. The HC55183 and HC55184 do not support uncommitted switch operation.

14. The HC55183 and HC55184 do not support the Forward Loopback operating mode.

15. The HC55183 and HC55184 do not support the Tip Open operating mode.

16. The power dissipation numbers are actual device measurements and will be less than worse case calculations based on data sheet supply

current limits.

17. Characterized with 2 x 10

s, and 10 x 1000s first level lightning surge waveforms (GR-1089-CORE).
