1 Guaranteed by design and characterization; not production tested.
2 All input signals are specified with tR = tF = 5 ns (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH)/2.
3 See Figure 3 and Figure 4.
4 This is measured with the load circuit of Figure 2. t13 determines maximum SCLK frequency in daisy-chain mode.
5 Daisy-chain mode only.
