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.
