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

‡ See section for fmax specifications.

§ This parameter applies to TIBPAL16R4’ and TIBPAL16R6’ 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.
