† _{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 with external feedback is not production tested but is calculated from the equation found in the fmax}
specification section.
# _{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.
