What are the key features of CD74HC151EE4?
- 8-to-1 multiplexing with complementary true and inverted outputs enables both non-inverting and inverting signal routing in a single IC
- 5.2 mA output current supports direct driving of logic inputs and small signal lines without external buffers
- HC CMOS family compatibility allows interfacing with 2 V to 6 V systems and TTL inputs for mixed-voltage designs
What is CD74HC151EE4 used for?
The CD74HC151EE4 is used in data routing, function generation, and parallel-to-serial conversion circuits where one of 8 input signals must be selected and forwarded. Microprocessor-based systems use it to reduce I/O pin count by multiplexing multiple analog or digital signals onto a shared data bus through 3-bit address selection. Digital designers also apply it in programmable logic function generation and signal switching applications in communications equipment and industrial controllers.

Frequently Asked Questions
How many inputs does the CD74HC151EE4 multiplex, and what is its output drive current capability?
The CD74HC151EE4 is an 8-input, 1-of-8 multiplexer that routes one of 8 data inputs to a single output based on a 3-bit address. It provides a maximum output low current of 5.2 mA, enabling direct connection to standard logic inputs, indicator LEDs with current-limiting resistors, or buffer inputs without additional drive stages in most HC-family designs.
What advantage do the complementary outputs of the CD74HC151EE4 provide in digital function generation?
The CD74HC151EE4 provides both a true (Y) and an inverted (W) output simultaneously, allowing designers to implement arbitrary 3-variable Boolean logic functions by connecting the 8 data inputs to Vcc or GND according to a truth table. This complementary output pair doubles the available logic functions from one package and eliminates the need for an external inverter gate when the opposite polarity is needed in data selector or signal routing applications.
When would a design team choose the CD74HC151EE4 DIP-16 version over an equivalent SOIC package for a keypad scanning circuit?
For a keypad scanning prototype or a small-batch production run where hand soldering or IC socket insertion is preferred, the CD74HC151EE4 16-pin DIP package allows direct breadboard placement and easy in-circuit replacement. Once the design is validated and production volume exceeds a few hundred units, engineers typically switch to an SOIC variant to reduce PCB footprint by roughly 50% and to support automated SMT assembly, lowering per-board cost.
