Figure 9. Pad output delay

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.

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.

8 Can be used on the tester.

9 This drive select value is not supported. If selected, it will be approximately equal to 11.

10 Slow Slew-Rate Controlled Output buffer. Contains an input buffer and weak pullup/pulldown.

11 Selectable high/low swing IO pad with selectable slew in high swing mode only.

12 Stand alone input buffer. Also has weak pull-up/pull-down.
