Functional Description
The device can also be configured as an 8 and 16-bit device by grounding the unused pins in the 10-bit and 20-bit configu-
rations respectively. The 8-bit configuration may also be achieved by connecting two of the 4-bit enables from the 4-bit con-
figuration together and connecting the remaining enable pin (OE) HIGH.
