SPI electrical characteristics

6.3

Dynamic characteristics

The voltages are referred to ground and currents are assumed positive, when the current

flows into the pin. 6 V

≤ V

S ≤ 24 V; all outputs open; Tj = -40 °C to 150 °C, unless otherwise

specified.

For definition of the parameters please see Figure 29 and Figure 30.
