SPI electrical characteristics

6.1

DC 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.

6.2

AC 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.
