= 60 Ω
Output slew rate measured across a 60 Ω resistive load.
Output turn ON and OFF delay time measured from 50% rising edge of CS to 80% and 20% of initial voltage.
Duration of fault before fault bit is set. Duration between access times must be greater than 450 µs to read faults.
This parameter is guaranteed by design but is not production tested.
Rise and Fall time of incoming SI,
Time required for valid output status data to be available on SO pin.
Time required for output status data to be terminated at SO pin.
Time required to obtain valid data out from SO following the rise of SCLK with 200 pF load.
This parameter is guaranteed by design. Production test equipment used 4.16 MHz, 5.5 V/3.1 V SPI Interface.
