Upper and lower logic threshold voltage levels apply to SI, CS, SCLK, RST, and SFPD inputs.
Hysteresis is characterized, but it is not production tested.
Input capacitance of SI CS, SCLK, RST, and SFPD for 0 V < V
DD
< 5.5 V. This parameter is guaranteed by design, but it is not production
tested.
Tri-state capacitance of SO for 0 V < V
