DESCRIPTION

The 74F182 is a high speed carry look-ahead generator. It accepts up to four pairs of active-Low Carry Propagate (P0, P1, P2, P3) and Carry Generate (G0, G1, G2, G3) signals and an active-High Carry input (Cn) and provides anticipated active-High carries (Cn+x, Cn+y, Cn+z) across four groups of binary adders. The 74F182 also has active-Low Carry Propagate (P) Carry Generate (G) outputs which may be used for further levels of look-ahead.

FEATURES

• Provides carry look-ahead across a group of four ALUs

• Multi-level look-ahead for high speed arithmetic operation over long word lengths
