Note 1: The 7450 and 7453 ICs have non-TTL compatible expander
inputs that are often not used in designs. These inputs are not tested.
Note 2: The 74LS51 and 74LS54 have differing pin connections and
functions from the standard 7451 and 7454 ICs. The test assumes that
the 'LS version is being tested - to test the standard version use the
numbers 7450 and 7453 respectively. In addition, the 74L86 IC has a
different pin out to the standard 7486 ICs, but it can be tested using the
74386 test.
Note 3: When testing these ICs the warning "EXT" will appear on the
LCD display. This means that external timing components are required
to test the IC. The timing components should be inserted into the socket
as given in following table:
IC
74122/74422
74123/74423
4528/4538/4098

Note 4: Certain differences exist between manufacturers parts with this
IC which may cause a FAIL result with ICs other than (Motorola)
MC14585 ICs. Consult the data sheets for full details.
