1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
2. Clock may be stopped (DC) for testing purposes, or when CDUSCC is in non-operational modes.
3. This product includes circuitry specifically designed for the protection of its internal devices from damaging effects of excessive static
4. Parameters are valid over specified temperature range.
5. All voltage measurements are referenced to ground (GND). For testing, all inputs except X1/CLK swing between 0.2V and 3.0V with a transi-
6. See Figure 20 for test conditions for outputs.
7. Tests for open drain outputs are intended to guarantee switching of the output transistor. Measurement of this response is referenced from
8. Execution of the valid command (after it is latched) requires 3 rising edges of X1 (see Figure 15).
9. These values were not explicitly tested; they are guaranteed by design and characterization data.
10. X1/CLK and X2 are not tested with a crystal installed.
11. X1/CLK frequency must be at least the faster of the receiver or transmitter serial data rate.
12. Timing is illustrated and referenced to the WRN and RDN inputs. The device may also be operated with CSN as the ‘strobing’ input. CSN
