1/ The above parameter shall be recorded before and after the required burn-in and life tests to determine the delta ().
2/ The I / I are measured for blank devices. Measurement is made with I/O configured as LVTTL.
IL IH
Programmed devices without the optional pull-up and pull-down resistors also comply with this limit.
3/ For programmed devices with the optional pull-up and pull-down resistors selected.
IIL / IIH parametric limits shown in table I are without the optional pull-up and pull-down resistors selected,
to calculate IIL / IIH with optional pull-up and pull-down resistors selected, use the table below:

RPULL-DOWN-MAX = VOLspec / IOLspec
RPULL-UP-MAX = (VCCImax – VOHspec) / IOHspec
Minimum output buffer resistance values depend on VCCI, drive strength selection, temperature, and process. For
board design considerations and detailed output buffer resistances, use the corresponding IBIS models located on the
manufacturer’s website (see 6.7 herein).
