† _{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 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.
