4-BIT ARITHMETIC LOGIC UNIT

The MC54/74F382 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. An Overflow output is provided for convenience in twos complement arithmetic. A Carry output is provided for ripple expansion. For high-speed expansion using a Carry Lookahead Generator, refer to the F381 data sheet.

• Performs Six Arithmetic and Logic Functions
• Selectable Low (Clear) and High (Preset) Functions
• LOW Input Loading Minimizes Drive Requirements
• Carry Output for Ripple Expansion
• Overflow Output for Twos Complement Arithmetic
