MC74AC151, MC74ACT151
1−of−8
Decoder/Demultiplexer
The MC74AC151/74ACT151 is a high−speed 8−input digital
multiplexer. It provides, in one package, the ability to select one line of
data from up to eight sources. The MC74AC151/74ACT151 can be
used as a universal function generator to generate any logic function of
four variables. Both true and complementary outputs are provided.
• Outputs Source/Sink 24 mA
• ′ACT151 Has TTL Compatible Inputs
