Philips Semiconductors Product specification Look-ahead carry generator 74F182 FEATURES • Provides carry look-ahead across a group of four ALUs • Multi-level look-ahead for high speed arithmetic operation over long word lengths PIN CONFIGURATION G1 P1 G0 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 VCC P2 G2 Cn Cn+x Cn+y G Cn+z 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.
