Package: Dual I.n-Llne and Flat Pack
The ITT946 and ITT949 elements are quad
two-input NAND/NOR lIates.
In addition to performing the positive NAND and
negative NO R logic functions.· the gates can be
cross-coupled to form a flip-flop or ~he outputs can
be tied together to perform the "wired OR"
function.
These quad two-input gates can also be wired to
perform the "exclusive OR" function. while two
elements can be wired together to form a full adder.
The ITT946 incorporates a 6K output pull-up
resistor which allows for a fan-out of up to 8 DTL
loads.
The ITT949 incorporates a 2 K output pull-up
resistor which allows for typically 30% faster rise
time with capacitive loads at a fan-out of up to 7
DTLloads.
