â All typical values are at VCC = 5 V, TA = 25°C.
â¡ 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 TIBPAL20R4â and TIBPAL20R6â only (see Figure 4 for illustration) and is calculated from the measured fmax with internal
feedback in the counter configuration.
