74F381
4-Bit Arithmetic Logic Unit
General Description
The 74F381 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. Carry
propagate and generate outputs are provided for use with
the 74F182 carry lookahead generator for high-speed
expansion to longer word lengths. For ripple expansion,
refer to the 74F382 ALU data sheet.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
