TYPICAL APPLICATIONS
The MC10H179 is a high–speed, low–power, standard
MECL complex function that is designed to perform the
look–ahead carry function. This device can be used with
the MC10H181 4–bit ALU directly, or with the MC10H180
dual arithmetic unit in any computer, instrumentation or
digital communication application requiring high speed
arithmetic operation on long words.
When used with the MC10H181, the MC10H179
performs a second order or higher look–ahead. Figure 2
shows a 16–bit look–ahead carry arithmetic unit. Second
order carry is valuable for longer binary words. As an
example, addition of two 32–bit words is improved from
30 nanoseconds with ripple–carry techniques. A block
diagram of a 32–bit ALU is shown in Figure 1. The
MC10H179 may also be used in many other applications.
It can, for example, reduce system package count when
used to generate functions of several variables.
