15.6. notes on TTL ICs
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 COMPONENTS
74122/74422 2.2
F between pins 24 and 26 of the ZIF socket, +ve to pin 26
74123/74423 2.2
F between pins 18 and 19 of the ZIF socket, +ve to pin 19
2.2
F between pins 27 and 26 of the ZIF socket, +ve to pin 27
4528/4538/4098 0.22
F between pins 13 and 14 of the ZIF socket.
0.22
F between pins 27 and 26 of the ZIF socket.
15.7. notes on CMOS ICs
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.
15.8. notes on memory ICs
Note 5: The 4532 32k DRAM is in fact a partially non-functional 64k
DRAM.
Four types exist, manufactured by OKI and TI who each
supply two types. The type numbers 45321 and 45322 are used for
OKI types, and 45323 and 45324 are used for TI types. The first
number in each case is for the low array version, and the second
number for the high array version. See the IC data sheets for further
details.
