Electrical Characteristics
(continued)
Table 9. Data Interface and Logic (Logic Inputs [CLK, NCS, and B0—B5] and Outputs [NDET])
1. Unless otherwise specified, all logic voltages are referenced to DGND.
2. This parameter is not tested in production; it is guaranteed by design and device characterization.
Table 10. Timing Requirements (CLK, B0—B5, and NCS)
1, 2
1. Unless otherwise specified, all times are measured from the 50% point of logic transitions.
2. These parameters are not tested in production; they are guaranteed by design and device characterization.
Table 11. Relay Driver (RDO)
1. Unless otherwise specified, all logic voltages are referenced to DGND.
2. This parameter is not tested in production; it is guaranteed by design and device characterization.
