MC10H181

4-Bit Arithmetic Logic Unit/

Function Generator

The MC10H181 is a high–speed arithmetic logic unit capable of

performing 16 logic operations and 16 arithmetic operations on two

four–bit words. Full internal carry is incorporated for ripple through

operation.

Arithmetic logic operations are selected by applying the appropriate

binary word to the select inputs (S0 through S3) as indicated in the

tables of arithmetic/logic functions. Group carry propagate (PG) and

carry generate (GG) are provided to allow fast operations on very long

words using a second order look–ahead. The internal carry is enabled

by applying a low level voltage to the mode control input (M).

When used with the MC10H179, full–carry look–ahead, as a second

order look–ahead block, the MC10H181 provides high–speed

arithmetic operations on very long words.

This 10H part is a functional/pinout duplication of the standard

MECL 10K family part with 100% improvement in propagation delay

and no increase in power supply current.
