1 Guaranteed by design and characterization; not production tested.
2 All input signals are specified with tr = tf = 5 ns (10% to 90% of DVCC) and timed from a voltage level of 1.2 V.
3 See Figure 2, Figure 3, and Figure 4.
4 Standalone mode only.
5 Measured with the load circuit of Figure 5.
6 Daisy-chain mode only.
