FAST AND LS TTL DATA
4-BIT ARITHMETIC LOGIC UNIT
The MC54/74F381 performs three arithmetic and three logic operations 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 F182 Carry Lookahead Generator for high-speed expansion
to longer word lengths. For ripple expansion, refer to the F382 ALU data
sheet.
Low Input Loading Minimizes Drive Requirements
Performs Six Arithmetic and Logic Functions
Selectable Low (Clear) and High (Preset) Functions
Carry Generate and Propagate Outputs for use with
Carry Lookahead Generator
