Numbers in parentheses are for EPF81500A devices only.

Row-to-IOE Connections

Figure 11 illustrates the connection between row interconnect channels

and IOEs. An input signal from an IOE can drive two separate row

channels. When an IOE is used as an output, the signal is driven by an

n-to-1 multiplexer that selects the row channels. The size of the

multiplexer varies with the number of columns in a device. EPF81500A

devices use a 27-to-1 multiplexer; EPF81188A, EPF8820A, EPF8636A, and

EPF8452A devices use a 21-to-1 multiplexer; and EPF8282A and

EPF8282AV devices use a 13-to-1 multiplexer. Eight IOEs are connected to

each side of the row channels.
