13 / 62 page ![]() STE2007 Electrical characteristics 13/62 3.5 Driver TxData mode Note: 1 Data Hold Time T1 depends on SCLK high time and Max Data Hold time. It is always 3-8ns before SCLK pulse falling edge 2 The input signal rise and fall times must be within 10ns. 3 Every timing is specified on the basis of 30% and 70% of VDDI. Note: 1 The input signal rise and fall times must be within 10ns. 2 Every timing is specified on the basis of 30% and 70% of VDDI. Table 11. Input signals change time Signal Symbol Parameter Min.
