test array
A test array that consists of product lines 48 and 49 has been added to these devices to allow testing
prior to programming. The test array is factory programmed as shown· below. Testing is accomplished
by connecting 00-03 to 110-113, PRE/DE to GND, and applying the proper input signals as shown in the
timing diagram. Product lines 48 and 49 must be deleted during user programming to avoid interference
with the programmed logic function.
