† _{All typical values are at VCC = 5 V, TA = 25°C.}
‡ _{See section for fmax specifications. fmax with external feedback is not production tested but is calculated from the equation found in the fmax}
section.
§ _{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.
