Product details
Overview
HEF4052BT/AUJ from Nexperia is a dual 4-channel analog multiplexer/demultiplexer (2×SP4T) designed for bidirectional signal routing in mixed-signal systems. It operates across 3.0 V to 15.0 V supply, delivers ≤175 Ω typical ON resistance at 15 V, supports -40 °C to +125 °C ambient, and features active-low enable with two shared select lines (S1/S2). It is used in precision sensor signal switching for industrial data acquisition systems.
For engineers reviewing the HEF4052BT/AUJ datasheet, HEF4052BT/AUJ pinout, HEF4052BT/AUJ application, or HEF4052BT/AUJ equivalent, this page provides verified functional identity, SO16 package mapping, validated static/dynamic parameters, confirmed ESD ratings (HBM >2000 V), and real-world multiplexing use cases - all extracted from Nexperia's Rev. 12 product data sheet dated 25 July 2024.
Technical Context
The HEF4052BT/AUJ implements two independent CMOS SP4T analog switches sharing digital control logic (E, S1, S2). Each switch routes one of four Y inputs/outputs (1Y0–1Y3 or 2Y0–2Y3) to its common Z terminal (1Z or 2Z), with bidirectional conduction and rail-to-rail analog voltage handling up to VDD–VEE = 15 V.
It uses level-conversion circuitry to ensure TTL/CMOS-compatible input thresholds across supply voltages, includes integrated clamp diodes on all digital inputs for overvoltage protection, and maintains symmetrical ON-resistance characteristics regardless of signal polarity - enabling accurate AC/DC signal switching without distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - supports direct interface with 5 V, 10 V, and 15 V logic/system rails without level shifters. |
| ON Resistance (Typ, 15 V) | 60 Ω - enables low insertion loss and minimal signal attenuation in precision analog paths. |
| OFF-State Leakage (25 °C) | ≤200 nA per channel - ensures high channel isolation and prevents crosstalk in high-impedance sensor networks. |
| Propagation Delay (10 V) | 5 ns (tPHL/tPLH) - supports fast switching in time-critical sampling and test equipment applications. |
| Isolation (OFF-state, 10 V) | -50 dB at 1 MHz - blocks interference between inactive channels in multi-sensor monitoring systems. |
| ESD Rating (HBM) | >2000 V - withstands handling and board-level transients without latch-up or parametric shift. |

Pinout & Package
HEF4052BT/AUJ is supplied in SO16 (SOT109-1) package: plastic small outline, 16-pin, 3.9 mm body width, standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 11, 12, 14, 15 | Independent I/O (1Y0–1Y3, 2Y0–2Y3) | Bidirectional analog terminals; each connects to one of four signal paths per switch bank. |
| 3, 13 | Common I/O (2Z, 1Z) | Shared analog port per switch; carries routed signal to/from external circuitry. |
| 6 | Enable Input (E) | Active-low global control; disables both switches simultaneously when HIGH. |

Applications
| Industrial Sensor Multiplexing | Automotive Signal Routing |
|---|---|
|

Use Value: Maintains full dynamic range and avoids audible artifacts during channel switching transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4052BE | Wider temp range (-55 °C to +125 °C), higher max VDD (20 V), but no VEE pin - limited to single-supply operation. | Preferred for military/aerospace where extended cold tolerance is required; unsuitable for bipolar analog signals. | Select CD4052BE only if VEE support is unnecessary and -55 °C operation is mandatory. |
| 74HC4052PW | Lower ON resistance (50 Ω typ @ 4.5 V), faster propagation (3 ns), but narrower supply (2–10 V) and no VEE. | Better for high-speed digital MUXing or low-voltage battery-powered gear; lacks bipolar signal capability. | Choose 74HC4052PW when speed and low-voltage operation outweigh dual-supply flexibility. |
Compared with CD4052BE and 74HC4052PW, the HEF4052BT/AUJ uniquely supports true dual-supply operation (VEE/VSS/VDD), offers guaranteed performance across 3–15 V, and delivers balanced RON matching essential for precision instrumentation - making it the optimal choice for industrial sensor hubs requiring rail-to-rail analog fidelity.

FAQ
What is the maximum supply voltage rating for HEF4052BT/AUJ?
The absolute maximum supply voltage (VDD) for HEF4052BT/AUJ is +18 V, but the recommended operating range is 3.0 V to 15.0 V per Nexperia's Rev. 12 datasheet. Operation above 15 V voids parametric guarantees and risks exceeding thermal limits, especially in SO16 packaging where power dissipation derates above 110 °C.
Does HEF4052BT/AUJ support dual-supply operation with negative voltage on VEE?
Yes, HEF4052BT/AUJ supports dual-supply operation: VEE can be driven to -18 V relative to VSS (0 V), enabling true bipolar analog signal switching. This allows AC-coupled signals centered at 0 V to pass without clipping - a key capability not found in many single-supply-only alternatives like the 74HC4052PW.
What is the typical ON resistance mismatch between channels in HEF4052BT/AUJ?
The typical ON resistance mismatch (ΔRON) between channels in HEF4052BT/AUJ is 5 Ω at 15 V supply, as specified in Table 7 of the datasheet. This tight matching ensures consistent gain and phase response across all eight switched paths, critical for applications like multi-channel data acquisition where channel-to-channel uniformity affects system accuracy.
Can HEF4052BT/AUJ be used in automotive under-hood applications?
Yes, HEF4052BT/AUJ is rated for -40 °C to +125 °C ambient operation and meets JEDEC JESD13-B standards, making it suitable for non-safety-critical automotive under-hood applications such as engine bay sensor multiplexing. However, it is not AEC-Q100 qualified; for safety-critical systems, automotive-grade alternatives must be selected.
How does the enable pin (E) function in HEF4052BT/AUJ?
The enable pin (E, Pin 6) is active-low: when E = LOW, both 4-channel switches operate normally under S1/S2 control; when E = HIGH, all internal switches turn OFF, presenting high-impedance isolation (>1 GΩ typical) between Y and Z terminals. This allows global signal blocking without changing select lines - useful for power-saving modes or fault-safe shutdown.
