74HC/HCT182 Look-ahead Carry Generator

The 74HC HCT182 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC HCT182 carry look-ahead generators accept 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). The devices provide anticipated active HIGH carries (Cn+x, Cn+y, Cn+z) across four groups of binary adders.The ,182, also has active LOW carry propagate (P) and carry generate (G) outputs which may be used for further levels of look-ahead.The Logic equations provided at the outputs are:Cn+x =G0 +P0 Cn Cn+y =G1 +P1 G0 +P1 P0 Cn Cn+z =G2 +P2 G1 +P2 P1 G0 +P2 P1 P0 Cn G= G3 + P3 G2 + P3 P2 G1 + P3 P2 P1 GO P= P3 P2 P1 P0 The '182' CAN also be used with binary ALU,s in an active LOW or active HIGH input operand mode. The connections to and from the ALU to the carry look-ahead generator are identical in both cases.
