Replacement verdict
Not a drop-in replacement
The 74HC4053PW and 74HC4015D,653 are functionally unrelated devices and cannot serve as substitutes for one another. The 74HC4053PW is a triple single-pole double-throw analog multiplexer/demultiplexer, while the 74HC4015D,653 is a dual 4-bit static shift register. Their core functions, signal paths, logic behavior, and pin configurations are fundamentally different, making direct replacement impossible without complete circuit redesign.

Key electrical and mechanical differences between the two devices
| Parameter | 74HC4053PW | 74HC4015D,653 | Why it matters |
|---|---|---|---|
| Function | Triple 2-channel analog multiplexer/demultiplexer | Dual 4-bit serial-in/parallel-out shift register | These devices perform fundamentally different logic functions, so they are not functionally substitutable in a circuit. |
| Logic Type | Analog switch / multiplexer | Shift register | The logic type determines the signal-processing behavior and cannot be interchanged between these parts. |
| Number of Circuits | 3 switches (triple 2:1) | 2 registers (dual 4-bit) | Circuit count affects how many independent channels or data paths the device can handle. |
| Number of Pins | 16 | 16 | Pin count affects package compatibility and PCB layout, though both share the same count here. |
| Supply Voltage Range | 2 V to 10 V | 2 V to 6 V | The usable supply voltage range determines compatibility with the system power rail and logic levels. |
| Propagation Delay | Typically around 4 ns at 5 V | Typically around 15 ns at 5 V | Propagation delay influences maximum operating speed and timing margins in the application. |
| Output Type | Analog signal pass-through (bidirectional) | Digital push-pull | Output type determines whether the device can handle analog signals or only digital logic levels. |
| Package / Mounting | TSSOP-16, surface mount | SO-16, surface mount | Package and mounting style affect footprint, assembly, and thermal characteristics on the PCB. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | The temperature range defines the environments in which the device can reliably operate. |

Frequently asked questions
Are the 74HC4053PW and 74HC4015D,653 functionally interchangeable?
No. The 74HC4053PW is a triple single-pole double-throw (SPDT) analog multiplexer/demultiplexer, while the 74HC4015D,653 is a dual 4-bit static shift register. They perform entirely different logic and signal-routing functions and cannot be substituted for one another.
What are the primary functions of the 74HC4053PW and 74HC4015D,653?
The 74HC4053PW contains three independent SPDT analog switches controlled by digital select inputs, suitable for analog and digital signal routing. The 74HC4015D,653 contains two independent 4-bit serial-in/parallel-out shift registers with separate clock and reset inputs.
Do the 74HC4053PW and 74HC4015D,653 use the same package type?
No. The 74HC4053PW is supplied in a TSSOP-16 package, while the 74HC4015D,653 is supplied in a SO-16 package. The package footprints and thermal characteristics differ, so PCB layout compatibility must be verified separately.
What supply voltage range is specified for the 74HC4053PW and 74HC4015D,653?
Both devices are 74HC-family CMOS parts typically specified for operation from 2.0 V to 6.0 V. Exact limits, including recommended operating conditions and absolute maximum ratings, should be confirmed from the respective manufacturer datasheets.
Can the 74HC4053PW be used to multiplex analog signals?
Yes. The 74HC4053PW is designed for analog and digital signal multiplexing/demultiplexing, with low on-resistance and bidirectional signal capability, making it suitable for analog signal routing within its specified voltage and current limits.
What is the role of the clock input on the 74HC4015D,653?
The 74HC4015D,653 shifts data one bit position on each low-to-high transition of its clock input. Each of the two 4-bit registers has its own clock input, allowing independent serial-to-parallel data conversion.
Are the control inputs of the 74HC4053PW and 74HC4015D,653 compatible with standard CMOS logic levels?
Yes. Both devices are 74HC-family CMOS ICs and their digital inputs are compatible with standard CMOS logic levels when operated at the same supply voltage. Logic threshold and input current specifications should be verified from the datasheets.
Which device is better suited for serial-to-parallel data conversion?
The 74HC4015D,653 is the appropriate choice for serial-to-parallel data conversion because it contains dual 4-bit shift registers. The 74HC4053PW does not perform shift-register functions and is intended for signal switching and multiplexing.
