Look-Ahead Carry Block

The MC14582B is a CMOS look–ahead carry generator capable of anticipating a carry across four binary adders or groups of adders. The device is cascadable to perform full look–ahead across n–bit adders. Carry, generate–carry, and propagate–carry functions are provided as enumerated in the pin designation table shown below.

• All Buffered Outputs

• Low Power Dissipation

• Diode Protection on All Inputs

• Supply Voltage Range = 3.0 Vdc to 18 Vdc

• Capable of Driving Two Low–power TTL Loads or One Low–Power

Schottky TTL Load over the Rated Temperature Range
