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.
Unless otherwise noted, all tests are pulsed
tests; therefore, T

The set-up and hold times are a measure of the time required for an input signal to propagate through the
first stage of the comparator to reach the latching circuitry. Input signals occurring before t
