Replacement verdict
Compatible functional replacement candidate
The 74HC4052D and 74HC4051D,652 are both high-speed CMOS analog multiplexers/demultiplexers from the 74HC series, offering comparable supply voltage ranges, ON-resistance characteristics, and switching performance. While they share the same package type and electrical family, the 74HC4052D is a dual 4-channel device whereas the 74HC4051D,652 is a single 8-channel device, making them functionally similar but not pin-to-pin equivalent. Designers should verify channel configuration and control logic requirements before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | 74HC4052D | 74HC4051D,652 | Why it matters |
|---|---|---|---|
| Multiplexer Configuration | Dual 4-channel (2 x 4:1) | Single 8-channel (8:1) | Determines how many independent signal channels can be routed and whether two separate 4:1 muxes or one 8:1 mux is required, directly affecting circuit topology and substitutability. |
| Number of Channels | 2 | 1 | The 74HC4052D provides two independent multiplexer/demultiplexer sections, while the 74HC4051D provides only one, so they are not drop-in replacements in multi-channel designs. |
| On-Resistance (RON) | Typically 80 Ω at VCC = 4.5 V | Typically 80 Ω at VCC = 4.5 V | On-resistance affects signal attenuation and voltage drop across the switch; similar values indicate comparable analog signal integrity. |
| Supply Voltage Range | 2 V to 10 V | 2 V to 10 V | Defines the compatible logic and analog supply levels; matching ranges allow use in the same system voltage domains. |
| Propagation Delay | Typically 9 ns at VCC = 4.5 V | Typically 9 ns at VCC = 4.5 V | Switching speed influences maximum usable signal frequency and timing margins in multiplexed signal paths. |
| Package | SO16 (SOIC-16) | SO16 (SOIC-16) | Physical footprint and pin count must match for PCB layout compatibility; identical SO16 packages simplify board-level substitution. |
| Logic Input Threshold | CMOS level, VCC dependent | CMOS level, VCC dependent | Control input thresholds determine compatibility with driving logic families and noise immunity. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Industrial temperature range ensures reliable operation in harsh environments and matches application requirements. |
| Pin Count | 16 | 16 | Same pin count allows use of identical PCB footprints, though internal pin functions differ between the two devices. |

Frequently asked questions
What is the main functional difference between the 74HC4052D and the 74HC4051D,652?
The 74HC4052D is a dual 4-channel analog multiplexer/demultiplexer, while the 74HC4051D,652 is a single 8-channel analog multiplexer/demultiplexer. The 74HC4052D contains two independent 4-channel switches, whereas the 74HC4051D,652 contains one 8-channel switch.
Are the 74HC4052D and 74HC4051D,652 pin-compatible?
No. The 74HC4052D and 74HC4051D,652 have different pin configurations and functions. The 74HC4052D uses two sets of channel-select inputs for its dual 4-channel architecture, while the 74HC4051D,652 uses three channel-select inputs for its single 8-channel architecture. They are not direct drop-in replacements.
What is the typical on-state resistance of these multiplexers?
Both the 74HC4052D and 74HC4051D,652 are specified with a typical on-state resistance (Ron) of approximately 80 Ω at VCC = 4.5 V and 70 Ω at VCC = 6 V, based on Nexperia datasheet parameters. Actual Ron varies with supply voltage, temperature, and input signal level.
What supply voltage range do the 74HC4052D and 74HC4051D,652 support?
Both devices operate over a recommended supply voltage range of 2.0 V to 10.0 V. They are specified for analog signal switching within the supply rails and are characterized for use in 2 V, 4.5 V, 6 V, and 9 V systems.
Can the 74HC4052D be used to replace the 74HC4051D,652 in an existing design?
Not directly. The 74HC4052D provides two independent 4-channel multiplexers, while the 74HC4051D,652 provides one 8-channel multiplexer. Replacing one with the other requires redesigning the channel selection logic, PCB layout, and possibly the signal routing. A direct substitution is not possible without validating these differences.
What are the package options for the 74HC4052D and 74HC4051D,652?
The 74HC4052D is typically offered in a 16-pin SOIC package (D suffix). The 74HC4051D,652 is also offered in a 16-pin SOIC package, but the ,652 suffix indicates a specific packing or ordering variant from Nexperia. Both use the same 16-pin SOIC footprint but have different internal switch configurations.
Do these multiplexers have break-before-make switching?
Yes. Both the 74HC4052D and 74HC4051D,652 feature break-before-make switching action, which prevents momentary shorting between channels during channel selection transitions. This is a standard characteristic of the 74HC405x family.
What are typical applications for the 74HC4052D versus the 74HC4051D,652?
The 74HC4052D is commonly used for differential signal multiplexing, dual-channel audio/video switching, and applications requiring two independent 4-channel selections. The 74HC4051D,652 is used for single-ended 8-channel analog signal selection, such as sensor array scanning, data acquisition, and signal routing where one of eight inputs is selected.
