TEST LEVEL CODES

All electrical characteristics are subject to the

following conditions:

All parameters having min/max specifications

are guaranteed. The Test Level column indi-

cates the specific device testing actually per-

formed during production and Quality Assur-

ance inspection. Any blank section in the data

column indicates that the specification is not

tested at the specified condition.
