6 Detailed Description

6.1 Overview

The CDx4ACT151 is a high speed silicon gate CMOS multiplexer well suited to multiplexing and data routing

applications. It contains a single 8:1 multiplexer.

The CDx4ACT151 operates asynchronously, with the Y output being equal to the input selected by the address

inputs (A, B, C). The W output is always the inverse of the Y output.

The strobe (G) input forces the Y output low, and the W output high, regardless of the state of other inputs.
