I/O leakage is the worst case of IOZL and IIL or IOZH and IIH respectively.
§Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second. VO is set at 0.5 V to
avoid test problems caused by test equipment ground degradation.
See section for fmax specifications. fmax does not apply for TIBPAL20L8’.
#This parameter applies to TIBPAL20R4’ and TIBPAL20R6’ only (see Figure 4 for illustration) and is calculated from the measured fmax with internal
feedback in the counter configuration.
||This parameter is the measurement of the difference between the fastest and slowest tpd (CLK-to-Q) observed when multiple registered outputs
are switching in the same direction.
