CD74AC251M96 is a quadruple 2-line to 1-line data selector/multiplexer. This device is designed by Texas Instruments, which is widely used for data communication between memory, peripherals, and microprocessors. It is a single-supply circuit, making it suitable for battery-operated applications. It comes in three package types—Dual-In-Line (DIP), Small Outline (SOIC) and Thin Small Outline (TSSOP).

Application Field

CD74AC251M96 is widely used in data multiplexing applications, such as those found in the automotive, automotive, industrial and communication markets. It is also used in analog-to-digital converters, digital-to-analog converters, multiplexers and demultiplexers, oscilloscopes and power supplies. Other applications include communication systems, security systems, and point-of-sale systems.

Working Principle

The CD74AC251M96 has four 2-to-1 multiplexers. When the enable pin is LOW or open, the output will be tri-stated regardless of the digital logic inputs. The multiplexers offer TTL-compatible logic levels and logic selections. It has a low-on-resistance which drives two TTL loads. The enable pins provide a control signal for output enable and latch control. It has a very low static power consumption and no static power dissipation. The output enable pin is active LOW, meaning it can be used for high-performance data multiplexing.

The device utilizes inverted inputs so that unconnected inputs can read as a Logic HIGH. This can be useful for applications requiring an active low output enable. Additionally, the multiplexers offer TTL compatible logic levels and logic selections. The enable pins are configurable as an active low enable or latch control. It has an output enable pin which is active LOW, so it can be used for high-speed data multiplexing. Lastly, it has a very low static power consumption and no static power dissipation.

The device is designed with a fail-safe feature that ensures the output remains tri-stated if the enable pin is Low or open. This feature can be useful for protecting data integrity. It also offers input clamp diodes to protect the inputs from electrostatic discharge (ESD) damage.

In summary, the CD74AC251M96 is a highly versatile device that is suitable for a variety of applications. It features low-on-resistance, TTL compatible logic levels and a fail-safe feature that keeps the output tri-stated if the enable pin is Low or open. Its inverted inputs can be useful for applications requiring an active low output enable. Lastly, it has a very low static power consumption and no static power dissipation.
