TEST LEVEL CODES

All electrical characteristics are subject

to the following conditions:

All parameters having min/max specifi-

cations are guaranteed. The Test Level

column indicates the specific device

testing actually performed during pro-

duction and Quality Assurance inspec-

tion. Any blank section in the data

column indicates that the specification

is not tested at the specified condition.

TEST LEVEL

TEST PROCEDURE

100% production tested at the specified temperature.

100% production tested at TA = +25 °C, and sample tested at the

specified temperatures.

III

QA sample tested only at the specified temperatures.

Parameter is guaranteed (but not tested) by design and characteriza-

tion data.

Parameter is a typical value for information purposes only.

100% production tested at TA = +25 °C. Parameter is guaranteed over

specified temperature range.

NOTES:

1. All input rise and fall times

are measured from 10% to

90% of +5 V. tR = tF = 5 ns.

2. If LD is activated while WR is

low, LD must stay low for t3 or

longer after WR goes high.
