NOTES:
2. These parameters are specified at high battery operation. For the HC55180 the external supply is set to high battery voltage, for the HC55181,
HC55182, HC55183 and HC55184, BSEL = 1.
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 = 0.795 VRMS for -100V devices, VRS = 0.663 VRMS for -85V devices and VRS = 0.575 VRMS
for -75V devices.
5. These parameters are specified at low battery operation. For the HC55180, the external supply is set to low battery voltage, for the HC55181,
HC55182, HC55183 and HC55184, BSEL = 0.
6. Forward Active and Reverse Active performance is guaranteed for the HC55180, HC55181 and HC55184 devices only. The HC55182 and
HC55183 are specified for Forward Active operation only.
