APEX 20KC Programmable Logic Device Data Sheet

Notes to Tables 21 through 35:

(1)

The IOH parameter refers to high-level output current.

(2)

The IOL parameter refers to low-level output current. This parameter applies to open-drain pins as well as output

pins.

(3)

VREF specifies center point of switching range.

Figure 31 shows the output drive characteristics of APEX 20KC devices.
