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
