The TC74HC153AF(EL) is a high-speed dual 4-to-1 line multiplexer from Toshiba Semiconductor and Storage, belonging to the High-speed CMOS (HC) logic family. This device operates with a supply voltage of 2V to 6V. It selects one of four data inputs from each of the two multiplexer sections based on the binary address applied to the select inputs (A and B). Each multiplexer also has a separate enable input (E). When the enable input is HIGH, the corresponding output is LOW, regardless of the select inputs. This is commonly used in data routing and selection applications.

Applications:

• Data selection and routing
• Parallel-to-serial conversion
• Logic function generation
• Address multiplexing
• Instrument and control panels

Features:

• High-speed operation: tpd = 14 ns (typ.) at VCC = 5V
• Wide operating voltage range: VCC = 2V to 6V
• Low power consumption: ICC = 1 μA (max.) at VCC = 5V
• Two independent 4-to-1 line multiplexers
• Separate enable inputs for each multiplexer
• Symmetrical output drive: |IOH| = IOL = 4 mA
• Wide operating temperature range: -40°C to +85°C
• Package: SOIC16 (Small Outline Integrated Circuit)

Benefits:

• Fast data selection for high-performance systems
• Low power consumption for energy efficiency
• Flexibility with two independent multiplexers
• Output control via enable inputs
• Suitable for a wide range of voltage levels
• Directly drives LEDs and other low-current loads
• Compact size for space-constrained applications

Additional Details:

The TC74HC153AF(EL) is fabricated using silicon gate CMOS technology. The device's inputs are equipped with clamp diodes. The 'AF' suffix denotes a surface mount package (SOIC16), and the 'EL' indicates an environmentally friendly lead-free version. The device is frequently used in microprocessor systems, data acquisition systems, and control circuits. The two multiplexer sections can be used independently or cascaded to create larger multiplexers. It is pin-compatible with standard TTL/CMOS multiplexers.
