4-184
FAST AND LS TTL DATA
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
