What are the key features of CD74HC151E?
- 8-to-1 multiplexer with complementary true and complement outputs for flexible logic routing in a single package
- HC/UH CMOS family with 50 pF load capacitance enables high-speed data selection with low quiescent current
- 16-pin PDIP package supports through-hole prototyping and reworkable production assembly for industrial designs
What is CD74HC151E used for?
The CD74HC151E is used in digital logic systems where one of 8 parallel data inputs must be selected and routed to a single output, such as in address decoders, data concentration circuits, and programmable logic test fixtures. Its complementary output pair simplifies cascading with downstream inverters or flip-flops in microcontroller peripheral expansion designs. It also appears in educational lab kits and FPGA prototype boards where through-hole PDIP components aid manual assembly and signal probing.

Frequently Asked Questions
How many data inputs does the CD74HC151E support, and what sink current can its output drive?
The CD74HC151E is an 8-input multiplexer that selects one of 8 data channels via a 3-bit address, and its output can sink up to 5.2 mA, making it compatible with standard HC-family logic loads and small LED indicators. The 50 pF load capacitance rating ensures signal integrity at typical HC switching speeds, and the complementary output provides both true and inverted versions of the selected input simultaneously.
In which microcontroller I/O expansion designs does the CD74HC151E reduce pin count most effectively?
The CD74HC151E is ideal for reading 8 digital sensor or switch inputs through only 3 address pins and 1 data pin on a microcontroller, reducing required I/O from 8 pins to 4 pins. This approach is common in keyboard matrices, rotary encoder arrays, and multi-sensor acquisition boards where the MCU scans inputs sequentially. The 16-pin PDIP package allows direct breadboard insertion during prototyping before final PCB layout.
When should a designer choose the CD74HC151E over a dual 4-to-1 multiplexer such as the CD74HC153 for a channel-selection task?
The CD74HC151E is the better choice when a single 8-channel mux is needed in one package rather than two separate 4-channel muxes, as it halves the component count and PCB area. Its single 3-bit address selects among 8 inputs simultaneously with a 50 pF load-rated output, whereas two CD74HC153 devices would require separate enables and separate address decoding logic, adding routing complexity in 8-input selection applications.
