NOTES:

7. The HC55180 does not provide battery switch operation. Therefore all battery voltage references will be made to VB. VB is the voltage applied to the common connection of the device VBL

and VBH pins. See the HC55180 Basic Application Circuit.

8. Ringing Voltage is measured with VRS = 0.839 VRMS for -100V devices, VRS = 0.707 VRMS for -85V devices and VRS = 0.619 VRMS for -75V devices. All measurements are at T = 25°C.

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

10. 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.

11. The HC55180, HC55183 and HC55184 are specified with a single longitudinal balance grade.

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

Ω per Tip and Ring Terminal.

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

14. The HC55180, HC55183 and HC55184 do not support uncommitted switch operation.

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

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

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

18. Characterized with 2 x 10

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

Electrical Specifications

Unless Otherwise Specified, TA = 0°C to 70°C for the HC55183, 184 only, all others -40°C to 85°C, VBL = -24V, VCC = +5V, AGND = BGND = 0V,

loop current limit = 25mA. All AC Parameters are specified at 600

Ω 2-wire terminating impedance over the frequency band of 300Hz to 3.4kHz.

Protection resistors = 0

Ω. (Continued)
