OE function

When the OE1, OE2, OE3 inputs are “H” than the outputs are driven to VEE regardless of the contents of the shift register.

Each of the three inputs drives it own set of outputs. This function is not synchronized with FX. The signal XDON can

override this function. In the Table below the relation between each OE1,2,3 and their related outputs is given.
