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
a73 Performs six arithmetic and logic functions
a73 Selectable LOW (clear) and HIGH (preset) functions
a73 LOW input loading minimizes drive requirements
a73 Carry output for ripple expansion
a73 Overflow output for twos complement arithmetic

Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
