Table 2: Pin Description

Table 3: Truth Table

X : Don’t Care

Z : High Impedance

Table 4: Absolute Maximum Ratings

Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is

not implied

1) IO absolute maximum rating must be observed

2) VO < GND
