AC Electrical Characteristics, MCLK Independent

The following specifications apply for AGND=DGND=DGNDI/O=0V, VA=VD=VDI/O=+5.0VDC, VREF IN = +2.0VDC, fMCLK=24MHz,

tMCLK=1/fMCLK, tr=tf=5ns, Rs=25¾, CL (databus loading) = 50pF/pin.

Boldface limits apply for TA=TJ=TMIN to TMAX; all other limits TA=TJ=25°C. (Notes 7 & 8)
