Package:. Dual In~Line and Flat Pack
The ITT930 and ITT961 elements are dual
four-input NAND/NOR gates.
In addition to performing the positive NAND and
negative NOR logic functions. the gates can be
cross-coupled to form a flip-flop or the outputs can
be tied together to perform the "wired OR"
function. Both gate inputs may be extended using
ITT933 elements to allow increased fan-in.
The ITT930 im;orporates a 6K output pull-up
resistor which allows for a fan-out of up to 8 DTL
loads.
The ITT961 incorporates a 2 K output pull-up
resistor which typically results in a 30% faster rise
time with capacitive loads at a fan-out of up to 7
DTL loads.

NOTES:
1. Above which useful life may be impaired.
2. Allow 300·C/Watt OJ-A for 1/4". x 1/4".
flatpack and dual in-line. Allow 50·C/Watt
OJ-C for TO-5; 180·C/Watt OJ-C for 1/4"
x 1/4" flatpack and dual in-line. Heat removal
in 1/4" x 1/4" flatpack is highly dependent
upon contact surfaces or air flow and on lead
attachment and thermal paths thru leads, as
well as number of soldered leads.
