† All typical values are at VCC = 5 V, TA = 25°C.

‡ 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 fmaxwithinternal

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.
