Additional Information

  • Summary

  • Reviews
The NTE74182 is a high-speed, look-ahead carry generator in a 16-lead plastic DIP-type package capable of anticipating a carry across four binary adders or group of adders. It is capable of performing full look-ahead across n-bit adders. Carry, generate-carry and propagate-carry functions are provided as enumerated in the pin designation table. When used in conjunction with the NTE74181, NTE74LS181 or NTE74S181 arithmetic logic unit (ALU), this generator provides high-speed carry look-ahead capability for any word length. This device generates look-ahead (anticipated carry) across a group of four ALU's and, in addition, other carry look-ahead circuits may be employed to anticipate carry across sections of four look-ahead packages up to n-bits.
Logic equations for this device 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
Cn + z = G2 + P2 G1 + P2 P1 G0 + P2 P1 P0 Cn
G = G3 + P3 G2 + P3 P2 G1 + P3 P2 P1 G0
P = P3 P2 P1 P0
Cn + x = Y0 (X0 + Cn)
Cn + y = Y1 [X1 + Y0 (X0 + Cn)]
Cn + z = Y1 {X2 + Y1 [X1 + Y0 (X0 + Cn)]}
Y = Y3 (X3 + Y2) (X3 + X2 + Y1) (X3 + X2 + X1 + Y0)
X = X3 + X2 + X1 + X0
