AC CHARACTERISTICS (Unless otherwise noted, parametric values are the same
between Commercial devices and Industrial devices.)
Notes:
1. The following BIU timing assumes that EDSEL = 1. Therefore, these parameters are specified with respect to the falling edge
of SCLK (SCLK↓). If EDSEL = 0, the same parameters apply but should be referenced to the rising edge of SCLK ↑).
2. Tested with CL set at 100 pF and derated to support the Indicated distributed capacitive Load. See the BIU output valid delay
vs. Load Chart.
3. Guaranteed by design–not tested.
4. tDATD is defined as the time required for outputs to turn high impedence and is not referred to as output voltage lead.
No.
