NOTES
1Includes acquisition time.
2Measured from the falling edge of OE/EOCEN (0.8 V) to the time at which the data lines/EOC cross 2.0 V or 0.8 V. See Figure 3.
3COUT = 100 pF.
4COUT = 50 pF.
5Measured from the rising edge of OE/EOCEN (2.0 V) to the time at which the output voltage changes by 0.5 V. See Figure 3; C OUT = 10 pF.
Specifications subject to change without notice.
