The TC74ACT153F is a high-speed CMOS dual 4-input multiplexer manufactured by Toshiba Semiconductor and Storage. Multiplexers, also known as data selectors, are used to select one of several input signals and route it to a single output. The TC74ACT153F provides two independent 4-input multiplexer circuits in a single package, offering a versatile solution for various digital logic applications.

Applications

• Data selection: Used to select one of multiple data sources in data acquisition systems.
• Address decoding: Employed in memory systems for address decoding.
• Logic function generation: Implements various logic functions by selectively routing input signals.
• Control signal routing: Routes control signals to different parts of a system.
• Parallel-to-serial conversion: Converts parallel data into a serial stream.

Features

• High-speed operation: Provides fast signal switching with a typical propagation delay of a few nanoseconds.
• Low power consumption: Minimizes power usage due to CMOS technology.
• Wide operating voltage range: Operates from a wide range of supply voltages.
• TTL compatible inputs: Compatible with standard TTL logic levels.
• Multiple enable inputs: Allows for independent control of each multiplexer.
