1 These are worst case values that are estimated from simulation and not tested. The values in the table are

simulated at VDD = 1.14 V to 1.32 V, VDDEH = 4.5 V to 5.5 V, TA = TL to TH

Output Delay (ns)2,3

Low-to-High /

High-to-Low

2 This parameter is supplied for reference and is not guaranteed by design and not tested.

3 Delay and rise/fall are measured to 20% or 80% of the respective signal.

Rise/Fall Edge (ns)3,4

4 This parameter is guaranteed by characterization before qualification rather than 100% tested.

5 In high swing mode, high/low swing pad Vol and Voh values are the same as those of the slew controlled output

pads

6 Medium Slew-Rate Controlled Output buffer. Contains an input buffer and weak pullup/pulldown.

7 Output delay is shown in Figure 9. Add a maximum of one system clock to the output delay for delay with respect

to system clock.
