1. Rload = 16 Ω at HB6 and HS7 in low on-resistance mode.

2. Rload = 128 Ω at HS8, HS9, HS11, HS12, HS13, HS14, HS15, HS0 and HS7 in high on-resistance mode.

3. Rload = 4 Ω at HB4,HB5.

4. Slope dVOUT/dt is measured between 20% and 80% of the final output voltage value.

5. Parameter specified by design, not tested in production.
