74F382
4-Bit Arithmetic Logic Unit
General Description
The 74F382 performs three arithmetic and three logic oper-
ations on two 4-bit words, A and B. Two additional Select
input codes force the Function outputs LOW or HIGH. An
Overflow output is provided for convenience in twos com-
plement arithmetic. A Carry output is provided for ripple
expansion. For high-speed expansion using a Carry Looka-
head Generator, refer to the 74F381 data sheet.
Features
s Performs six arithmetic and logic functions
s Selectable LOW (clear) and HIGH (preset) functions
s LOW input loading minimizes drive requirements
s Carry output for ripple expansion
s Overflow output for twos complement arithmetic

may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
