Notes to tables:
(1) Operating conditions: VCC = 5 V ± 5%, TA = 0° C to 70° C for commercial use.
(2) Measured with three I/O outputs switching.
(3) The tPZX and tPXZ parameters are measured at ± 0.5 V from steady-state voltage that is driven by the specified
output load. The tPXZ parameter is measured with CL = 5 pF and with all eight outputs switching.
