LOGIC DIAGRAM
TYPICAL APPLICATIONS
The MC10H179 is a highspeed, lowpower, standard
MECL complex function that is designed to perform the
lookahead carry function. This device can be used with the
MC10H181 4bit 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 lookahead. Figure 2
shows a 16bit lookahead carry arithmetic unit. Second
order carry is valuable for longer binary words. As an
example, addition of two 32bit words is improved from 30
nanoseconds with ripplecarry techniques. A block diagram
of a 32bit 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.
