简 介:MC74AC352 MC74ACT352 Dual 4Input 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 DUAL 4-INPUT MULTIPLEXER
