1 / 9 page © 1999 Fairchild Semiconductor Corporation DS009929 www.fairchildsemi.com November 1988 Revised November 1999 74AC157 • 74ACT157 Quad 2-Input Multiplexer General Description The AC/ACT157 is a high-speed quad 2-input multiplexer. Four bits of data from two sources can be selected using the common Select and Enable inputs. The four outputs present the selected data in the true (noninverted) form. The AC/ACT157 can also be used as a function generator. Features s ICC and IOZ reduced by 50% s Outputs source/sink 24 mA s ACT157 has TTL-compatible inputs Ordering Code: Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code. Logic Symbols IEEE/IEC Connection Diagram Pin Descriptions FACT is a trademark of Fairchild Semiconductor Corporation.
