MC74AC352, MC74ACT352
Dual 4−Input 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
