Typical Applications
CD74AC151M96 is suitable for 6 applications: Data Selection in Microprocessors, Parallel-to-Serial Converter, Boolean Function Generator, Data Source Selector, Communication Channel Selection, Test and Measurement Equipment.
Data Selection in Microprocessors
The CD74AC151M96 is used to select one of multiple data sources to a single bus, enabling efficient data routing in microprocessor systems. Its high speed (5.5 ns propagation delay) ensures minimal latency in critical paths. The wide supply range (1.5V to 5.5V) allows interfacing with both 3.3V and 5V logic. The balanced noise immunity (30% of supply) ensures reliable operation in noisy digital environments. This multiplexer can be used to expand I/O capabilities or to implement register selection logic.
Recommended
Parallel-to-Serial Converter
The CD74AC151M96 can convert parallel data into a serial stream by sequentially selecting each input using the select lines. This is useful in communication interfaces where data must be transmitted serially. The device's high speed supports high data rates, and its low power consumption is ideal for portable devices. The enable input allows for easy synchronization with external timing signals. This application is common in UART, SPI, and other serial protocols.
Recommended
Boolean Function Generator
By connecting the data inputs to logic levels, the CD74AC151M96 can implement any 3-variable Boolean function. This is useful in programmable logic applications where a simple, low-cost function generator is needed. The device's high speed and low power make it suitable for real-time control systems. The enable input can be used to implement additional logic functions. This approach is often used in educational projects and simple digital circuits.
Recommended
Data Source Selector
The CD74AC151M96 can select between multiple data sources, such as sensors or memory banks, and route the selected data to a single output. This is essential in data acquisition systems where multiple inputs need to be monitored. The device's wide operating temperature range (-55Β°C to +125Β°C) makes it suitable for industrial environments. The high output current (24 mA) allows direct driving of LEDs or other loads. The enable input provides a simple way to disable the output when not needed.
Recommended
Communication Channel Selection
In communication systems, the CD74AC151M96 can be used to select between different channels or data streams. Its high speed ensures minimal signal delay, and its low power consumption is beneficial for battery-powered devices. The device's balanced noise immunity helps maintain signal integrity in RF environments. The select lines can be controlled by a microcontroller to dynamically switch channels. This application is common in radio receivers, multiplexed telemetry, and network switches.
Recommended
Test and Measurement Equipment
The CD74AC151M96 is used in test equipment for signal routing and selection. Its high speed and precision make it ideal for automated test systems that need to switch between multiple test points. The device's wide supply range allows integration with various logic levels. The enable input provides a convenient way to isolate the output during calibration. The compact SOIC-16 package saves board space in dense test equipment.

Key Differentiators
- Wide supply voltage range (1.5V to 5.5V) (vs SN74HC151NSR)
- Faster propagation delay (5.5 ns at 5V) (vs SN74HC151NSR)
- Higher output current (24 mA) (vs 74HC151D)
Design Notes
The CD74AC151M96 operates from 1.5V to 5.5V. Ensure the supply voltage is within the recommended range and is adequately decoupled with a 0.1uF ceramic capacitor placed close to the VCC pin. At higher supply voltages, the device consumes more power, so consider the thermal implications in high-density designs.
For high-speed operation, keep traces short and avoid excessive capacitive loading on the output. Use a ground plane to minimize noise and ensure signal integrity. Place the device close to the signal source to reduce propagation delays. The SOIC-16 package has a thermal pad that should be connected to ground for better heat dissipation.
Do not leave the enable input (G) floating; it should be tied to a defined logic level. When the device is disabled, the output is high-impedance, which can cause floating nodes if not properly terminated. Also, ensure that the select lines (A, B, C) are stable before the enable is asserted to avoid glitches on the output.
