What are the key features of CD74HC157M96G4?
- Quad 2-to-1 multiplexer packs 4 independent select channels in a single 16-pin SOIC, replacing 4 discrete gates and reducing PCB component count
- Wide supply voltage range of 2V to 6V with full CMOS input compatibility enables direct use in both 3.3V and 5V logic systems without level-shifting
- Fast propagation delay of approximately 9 ns at 5V and 50 pF load allows reliable signal routing at bus frequencies up to 50 MHz in glue-logic designs
- Active-low common SELECT and ENABLE inputs allow all 4 channels to be controlled simultaneously with a single control line, simplifying multi-bus switching logic
What is CD74HC157M96G4 used for?
The CD74HC157M96G4 is widely used in microprocessor and FPGA-based systems as a data bus multiplexer, routing one of two 4-bit input buses to a common output based on a single select line. Its 2V to 6V supply range makes it suitable for mixed-voltage board designs where 3.3V and 5V logic domains coexist, such as in industrial PLCs and embedded communication interfaces. Signal routing applications in test equipment, memory address multiplexing, and display controllers also benefit from its low propagation delay and compact 16-pin SOIC footprint.

Frequently Asked Questions
How fast can the CD74HC157M96G4 route signals and what is its propagation delay at 5V?
The CD74HC157M96G4 has a typical propagation delay of approximately 9 ns at 5V with a 50 pF load capacitance, allowing reliable signal routing at bus clock frequencies up to 50 MHz. At 3.3V the propagation delay increases to around 14 ns, so designers working with high-speed buses should verify setup and hold timing margins if the device is used in synchronous data-routing paths.
In what supply voltage range does the CD74HC157M96G4 operate and how does this affect system integration?
The device operates from 2V to 6V, covering both 3.3V and 5V logic families without external level-shifting components. The output drive current is 4 mA at 5V, sufficient to drive one standard CMOS load with a 50 pF capacitance, making it compatible with most microcontroller GPIO and FPGA I/O standards in the VCC_IO range of 2.5V to 5V.
How does the ENABLE input on the CD74HC157M96G4 simplify multi-bus designs?
The active-low ENABLE input disables all 4 output channels simultaneously when asserted LOW, forcing all outputs to logic LOW regardless of SELECT or input states. This allows the device to share a common output bus with other multiplexers or tri-state drivers without logic contention, enabling straightforward 8-bit or 16-bit bus expansion by paralleling 2 or 4 CD74HC157 devices controlled by a shared 1-bit enable signal.
For a compact board layout, how much PCB area does the CD74HC157M96G4 SOIC-16 package occupy?
The 16-pin SOIC package has a body size of approximately 9.9 mm × 3.9 mm with a 1.27 mm lead pitch, occupying roughly 40 mm² of PCB area. Compared to a 16-pin DIP package at 200 mm², the SOIC reduces footprint by 80%, making it well-suited for high-density PCB designs where board area is allocated to fewer than 50 mm² per logic IC.
When is the CD74HC157M96G4 a practical alternative to an FPGA internal LUT for 4-channel signal selection?
The CD74HC157M96G4 is cost-effective when signal selection is needed outside the FPGA I/O fabric, such as routing analog or mixed-signal lines where FPGA pins carry only digital control. Using the external MUX frees 8 FPGA I/O pins for other functions, and at a unit cost of under $0.50 in volume, it avoids the need for a larger FPGA package with 8 additional I/O pins just to implement 4 two-to-one mux paths at 50 pF loads.
