MC74ACT352
Dual 4ĆInput Multiplexer
The MC74AC352/74ACT352 is a very high-speed dual 4-input multiplexer with
common Select inputs and individual Enable inputs for each section. It can select
two bits of data from four sources. The two buffered outputs present data in the
inverted (complementary) form. The MC74AC352/74ACT352 is the functional
equivalent of the MC74AC153/74ACT153 except with inverted outputs.
• Inverted Version of the MC74AC153/74ACT153
• Separate Enables for Each Multiplexer
• Outputs Source/Sink 24 mA
• ′ACT352 Has TTL Compatible Inputs
