Typical Applications
CD74AC151M96 is suitable for 6 applications: Data Selection in Microprocessors, Parallel-to-Serial Converters, Boolean Function Generators, Data Source Selectors, Communication Channel Selection, Test Equipment Signal Routing.
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, and its wide supply range (1.5V-5.5V) allows interfacing with various logic levels. The 24 mA output drive capability can directly drive bus lines without additional buffers, simplifying design and reducing component count.
Recommended
Parallel-to-Serial Converters
In parallel-to-serial conversion, the CD74AC151M96 selects one of eight parallel inputs sequentially, producing a serial output. Its balanced propagation delays and output transition times minimize skew, ensuring accurate data transmission. The device's low power consumption makes it ideal for battery-powered portable devices where efficiency is critical. The active-low enable input allows easy synchronization with control logic.
Recommended
Boolean Function Generators
The CD74AC151M96 can implement any Boolean function of three variables by connecting the function's truth table to the data inputs and using the select lines as variables. This flexibility makes it a versatile building block in programmable logic. Its high noise immunity (30% of supply voltage) ensures reliable operation in electrically noisy environments, such as industrial control systems. The wide temperature range (-55Β°C to +125Β°C) supports harsh operating conditions.
Recommended
Data Source Selectors
The CD74AC151M96 is used to select between multiple data sources, such as sensors or memory banks, and route the chosen source to a single output. Its high-speed operation (5.5 ns) ensures real-time data acquisition, and its 24 mA output drive can directly feed ADCs or other loads. The device's low power dissipation is beneficial in portable instrumentation, extending battery life. The enable input provides a simple method to disable the output when not needed.
Recommended

Key Differentiators
- Wider supply voltage range (1.5V-5.5V) compared to HC family (vs SN74HC151NSR)
- Higher output drive current (24 mA) vs HC family (vs SN74HC151NSR)
- Wider operating temperature range (-55Β°C to +125Β°C) vs onsemi 74AC151SC (vs 74AC151SC)
Design Notes
Place decoupling capacitors (0.1uF) close to the VCC pin (pin 16) and GND pin (pin 8) to minimize power supply noise. Use a solid ground plane to reduce ground bounce and ensure signal integrity for high-speed operation.
Ensure that the select lines (A, B, C) and enable input (G) are driven to valid logic levels to avoid undefined states. When the device is disabled (G high), the output Y is high-impedance; use a pull-up or pull-down resistor to prevent floating nodes.
For high-speed signals, keep trace lengths short and matched between the data inputs and the output to minimize skew. The CD74AC151M96 has balanced propagation delays, but PCB layout can introduce additional skew. Use controlled impedance traces if routing over long distances.
