Replacement verdict
Not a drop-in replacement
The 74HCT4052D and 74HCT04D,653 are functionally unrelated devices and cannot serve as substitutes for one another. The 74HCT4052D is a dual 4-channel analog multiplexer/demultiplexer, while the 74HCT04D,653 is a hex inverter. Their differing logic functions, channel configurations, and signal-handling characteristics make direct replacement infeasible in any design.

Key electrical and mechanical differences between the two devices
| Parameter | 74HCT4052D | 74HCT04D,653 | Why it matters |
|---|---|---|---|
| Function | Dual 4-channel analog multiplexer/demultiplexer | Hex inverter | These devices perform completely different logic functions, so they are not functionally substitutable in a circuit. |
| Logic Type | Analog switch / multiplexer | Inverter | The logic type determines the signal-processing behavior and cannot be interchanged between these parts. |
| Number of Circuits | 2 | 6 | The number of independent channels affects how many signals can be handled per package. |
| Number of Channels per Circuit | 4 | 1 | Channel count per circuit determines the multiplexing capability versus single-signal inversion. |
| Supply Voltage Range | 4.5 V to 5.5 V | 4.5 V to 5.5 V | Both operate in the standard 5 V HCT logic range, so supply compatibility is similar. |
| On-State Resistance | Typically 70 Ω at 5 V | Not applicable | On-state resistance is a key analog-switch parameter and does not apply to a digital inverter. |
| Propagation Delay | Typically 8 ns at 5 V | Typically 12 ns at 5 V | Propagation delay affects timing performance in high-speed digital systems. |
| Output Drive Current | ±4 mA | ±4 mA | Output drive capability determines the load that can be driven directly by the device. |
| Package | SO16 | SO14 | Different package pin counts and footprints prevent direct board-level substitution. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Both support industrial temperature ranges, so environmental tolerance is comparable. |

Frequently asked questions
What are the primary functions of the 74HCT4052D and the 74HCT04D,653?
The 74HCT4052D is a dual 4-channel analog multiplexer/demultiplexer, while the 74HCT04D,653 is a hex inverter. They serve entirely different signal-routing and logic functions and are not interchangeable.
Are the 74HCT4052D and 74HCT04D,653 pin-compatible?
No. The 74HCT4052D is typically supplied in a 16-pin SOIC package, whereas the 74HCT04D,653 is supplied in a 14-pin SOIC package. The pin counts and pin functions differ, so they cannot share the same PCB footprint.
Do both devices operate from the same supply voltage range?
Both are HCT-family logic devices and are specified for a nominal 5 V supply, with the 74HCT4052D typically rated for 4.5 V to 5.5 V operation and the 74HCT04D,653 similarly specified for 4.5 V to 5.5 V. Exact limits should be confirmed on the respective manufacturer datasheets.
Can the 74HCT4052D be used to invert a digital signal like the 74HCT04D,653?
No. The 74HCT4052D is an analog switch/multiplexer and does not provide logic inversion. Signal inversion requires a logic gate such as the 74HCT04D,653.
Which device is suitable for switching analog signals?
The 74HCT4052D is intended for analog signal multiplexing/demultiplexing and can pass analog levels within its specified signal range. The 74HCT04D,653 is a digital hex inverter and is not intended for analog signal routing.
Are the logic input thresholds of the 74HCT4052D and 74HCT04D,653 compatible with TTL levels?
Yes. Both are HCT-family devices, which are designed for TTL-compatible input thresholds when operated at 5 V, allowing direct interfacing with TTL-level logic in appropriate designs.
Can the 74HCT04D,653 drive the control inputs of the 74HCT4052D?
In principle, a 74HCT04D,653 output can drive 74HCT4052D control inputs because both are HCT-family devices operating at the same logic supply, provided fan-out, loading, and timing are verified against the datasheets. This is a functional interface, not a substitution.
Do the 74HCT4052D and 74HCT04D,653 have the same propagation delay specifications?
No. Propagation delay depends on the internal function and load conditions. The 74HCT04D,653 inverter and the 74HCT4052D multiplexer have different internal architectures and therefore different timing parameters, which must be checked individually on the manufacturer datasheets.
