SPI - electrical characteristics
VS = 8 to 16 V, VCC = 4.5 to 5.3 V, Tj = - 40 to 150 °C, unless otherwise specified. The
voltages are referred to GND and currents are assumed positive, when the current flows into
the pin.
Note:
Value of input capacity is not measured in production test. Parameter guaranteed by design.
