What are the key features of CD74HC151EG4?
- 8-to-1 single-channel multiplexer with 3-bit binary address selects one of 8 data inputs, reducing wiring complexity in analog or digital routing applications
- Wide 2 V to 6 V supply range with CMOS high-speed logic compatible with both 3.3 V and 5 V microcontroller I/O standards
- Complementary true (Y) and inverted (W) outputs provide built-in signal inversion without an additional NOT gate, saving component count
- 16-DIP through-hole package (EG4 RoHS-compliant suffix) ideal for breadboard prototyping and field-serviceable industrial PCBs
What is CD74HC151EG4 used for?
CD74HC151EG4 is used in microcontroller designs to expand analog multiplexing by routing one of 8 sensor signals to a single ADC input under 3-bit GPIO control, reducing the required number of ADC channels. It fits digital logic selection circuits in test equipment and data acquisition systems where one of 8 parallel data streams must be selected and forwarded to downstream processing. The complementary output feature also makes it useful for generating balanced differential signals from single-ended digital sources in communication board designs.

Frequently Asked Questions
How many data inputs can CD74HC151EG4 multiplex and how are they selected?
CD74HC151EG4 multiplexes 8 data inputs (I0 through I7) selected by a 3-bit binary address applied to pins A, B, and C. All 8 combinations of the 3-bit address are decoded internally, routing the chosen input to both the true output Y and the complementary output W simultaneously.
What propagation delay does CD74HC151EG4 exhibit from address change to output settling at 5 V?
At 5 V supply, CD74HC151EG4 has a typical propagation delay of approximately 9 ns from address input change to stable output, and 11 ns maximum at 25°C. This sub-15 ns switching makes it practical for use in logic circuits requiring address decode cycles as short as 20 ns.
For a battery-powered sensor hub, how does CD74HC151EG4 compare to a dedicated analog MUX like CD4051B?
CD74HC151EG4 is a digital multiplexer passing logic-level signals (0 V to VCC), suitable for digital data routing at 2 V to 6 V supply. CD4051B handles true analog signals up to 15 V bipolar supply. For routing 8 analog sensor voltages to one ADC, CD4051B is the correct choice; CD74HC151EG4 suits digital signal selection at logic levels only.
Can CD74HC151EG4 be used to generate a lookup-table output from 3 GPIO inputs without a microcontroller?
Yes, CD74HC151EG4 implements a 3-input, 1-output combinational logic function by wiring I0–I7 to fixed Vcc or GND according to the desired truth table. The 3 address pins A, B, C become input variables, and the Y output produces the programmed Boolean function using only 8 pull-up/pull-down resistors—no microcontroller or FPGA required.
