What are the key features of CD74AC251M96?
- 8-input multiplexer with 3-state outputs for clean bus sharing and signal routing in digital systems
- AC-family CMOS logic with 50 pF load capacitance rating and 24 mA output sink current for reliable high-speed operation
- 16-pin SOIC (R-PDSO-G16) package with RoHS-compliant e4 designation, supporting modern green manufacturing requirements
What is CD74AC251M96 used for?
The CD74AC251M96 is used in data-routing circuits where one of 8 parallel digital signals must be selected and driven onto a shared 3-state bus, such as in microprocessor address/data multiplexing and FPGA I/O expansion. Its AC-family speed and 24 mA output current also make it well-suited for driving backplane traces with up to 50 pF load in telecommunications and industrial control boards. Signal-selection stages in test and measurement equipment benefit from its clean 3-state switching and compact 16-pin SOIC footprint.

Frequently Asked Questions
How many input channels does CD74AC251M96 support, and what output structure does it use?
The CD74AC251M96 provides 8 input channels that are selected via 3 binary address lines, with the chosen signal routed to a single 3-state output. The 3-state output can sink up to 24 mA, allowing multiple devices to share a common bus without contention when the output-enable pin is deasserted.
For a 50 pF PCB trace in a backplane design, can CD74AC251M96 drive the line reliably?
Yes, the CD74AC251M96 is rated for a 50 pF load capacitance, which directly matches the specified load for its AC-family timing parameters. At this load it maintains the propagation delay guarantees of the AC logic family, making it reliable for backplane and multi-card bus environments where trace capacitance commonly reaches 50 pF.
When is CD74AC251M96 a better choice than an HC-family 8-input mux for high-frequency digital routing?
The AC-family CD74AC251M96 offers significantly faster switching speeds than HC-family equivalents because AC-family devices are designed for higher drive strength and lower propagation delays at the same supply voltage. When the design requires switching frequencies above 50 MHz or driving 50 pF loads with tight timing margins, the AC family's 24 mA output sink capability and faster edge rates outperform typical HC-series multiplexers.
