The CD74HC157N is a high-speed CMOS quad 2-input multiplexer. It is part of the CD74HC series logic family from Intersil (now Renesas). This device selects one of two 4-bit data sources based on the state of a single select input. The selected data is then presented at the output.

Applications

• Data selection and routing
• Address decoding
• Memory mapping
• Function generation
• Logic function multiplexing

Features

• High Speed Operation: Provides fast switching speeds for high-performance applications.
• Low Power Consumption: Typical quiescent current of 2 μA.
• Wide Operating Voltage Range: Operates from 2V to 6V.
• High Noise Immunity: Provides reliable operation in noisy environments.
• Fanout (Over Temperature Range): Outputs can drive 10 LSTTL loads.
• Quad 2-Input Multiplexer: Selects one of two 4-bit data sources.
• Non-Inverting Outputs: Outputs present the selected data directly.

Benefits

• Versatile Data Selection: Enables flexible selection of data sources for various applications.
• Reduced Power Consumption: Minimizes power consumption in battery-powered devices.
• Improved System Performance: Provides fast switching speeds for improved system performance.
• Enhanced Reliability: Offers high noise immunity for reliable operation.
