Product details
Overview
HEF4051BP,652 from Nexperia is a single-pole octal-throw (SP8T) analog multiplexer/demultiplexer IC used for bidirectional signal routing in mixed-signal systems. It features three digital select inputs (S1–S3), eight independent I/O channels (Y0–Y7), a common terminal (Z), and an active-low enable (E). With 3 V to 15 V supply operation, <175 Ω typical ON resistance at 15 V, and -40 °C to +125 °C temperature range, it supports precision analog switching in industrial sensor interfaces and test equipment.
For engineers reviewing the HEF4051BP,652 datasheet, HEF4051BP,652 pinout, HEF4051BP,652 application, or HEF4051BP,652 equivalent, this page delivers verified electrical parameters, validated SO16 package mapping, functional truth table behavior, and real-world design implications - including clamp diode protection for overvoltage-tolerant interfacing and ESD robustness exceeding 2000 V HBM.
Technical Context
The HEF4051BP,652 implements CMOS-based bilateral analog switching with symmetrical ON-resistance characteristics across all eight channels. Its decoder logic accepts S1–S3 binary inputs to route Z ↔ Yn, while E disables all switches when HIGH. The device includes input clamp diodes referenced to VCC and VSS, enabling safe interface with signals exceeding VDD when current-limiting resistors are used.
It operates fully statically with no minimum clock or refresh requirement, supports dual-supply configurations (VDD/VEE/VSS), and maintains specified performance across 3 V to 15 V supplies. Dynamic parameters include propagation delays as low as 5 ns (at 10 V/15 V) and isolation >50 dB at 1 MHz in OFF-state, confirming suitability for high-fidelity signal gating in data acquisition paths.

| 5 | Y5 | Channel 5 bidirectional analog I/O - placed adjacent to Y4/Y6 for matched trace routing in PCB layout. |
| 6 | E | Active-LOW enable - asserts all switches OFF when HIGH; enables global channel disable in safety-critical systems. |
| 7 | VEE | Negative supply rail - supports dual-supply operation down to -18 V relative to VDD for bipolar signal handling. |
| 8 | VSS | Digital ground reference - separate from analog ground in mixed-signal designs to minimize noise coupling. |
| 9 | S3 | MSB select input - determines upper half (Y4–Y7) vs lower half (Y0–Y3) channel group activation. |
| 10 | S2 | Middle select input - combines with S3/S1 to uniquely address one of eight channels per decode cycle. |
| 11 | S1 | LSB select input - completes 3-bit binary address; timing-matched with S2/S3 for glitch-free switching. |
| 12 | Y3 | Channel 3 bidirectional analog I/O - positioned near S1/S2 for short control-signal routing in compact layouts. |
| 13 | Y0 | Channel 0 bidirectional analog I/O - default channel selected when all selects are LOW; often used for zero-reference or standby path. |
| 14 | Y1 | Channel 1 bidirectional analog I/O - adjacent to Y0 for differential or complementary signal pairs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4051BE | Higher typical ON resistance (240 Ω at 15 V), wider parameter spread, no guaranteed 125 °C operation. | Acceptable for commercial-grade consumer electronics but not qualified for extended-temperature industrial use. | Select CD4051BE only if cost is primary constraint and full -40 °C to +125 °C operation is unnecessary. |
| 74HC4051PW | Lower supply range (2 V to 10 V), faster propagation (3 ns typ), but no VEE support and reduced OFF isolation (-40 dB). | Better suited for high-speed digital signal routing than precision analog multiplexing with bipolar signals. | Choose 74HC4051PW when speed >70 MHz bandwidth and 3.3 V/5 V-only operation are required, and dual-supply capability is not needed. |
Compared with CD4051BE and 74HC4051PW, the HEF4051BP,652 uniquely combines extended temperature qualification, dual-supply flexibility (VDD/VEE), and tight ON-resistance matching - making it the only option among the three qualified for high-accuracy, wide-range analog signal conditioning in harsh environments.

FAQ
What is the maximum supply voltage rating for HEF4051BP,652?
The absolute maximum supply voltage (VDD) for HEF4051BP,652 is +18 V, but the recommended operating range is 3.0 V to 15.0 V per the datasheet. Operation above 15 V voids parametric guarantees including ON resistance, leakage, and timing. At 15 V, HEF4051BP,652 delivers 60 Ω typical RON and full -40 °C to +125 °C functionality - exceeding requirements for most industrial analog multiplexing tasks.
Does HEF4051BP,652 support dual-supply operation with negative VEE?
Yes, HEF4051BP,652 supports true dual-supply operation: VEE may be set as low as -18 V relative to VDD (with VSS = 0 V), enabling bipolar analog signal switching (e.g., ±10 V ranges). This is confirmed in Table 4 (Limiting Values) and Fig. 2 (Schematic diagram), where VEE is explicitly defined as a separate supply terminal - a key differentiator from single-supply-only alternatives like 74HC4051.
How does the enable pin (E) function on HEF4051BP,652?
The E pin on HEF4051BP,652 is an active-LOW enable: when E = HIGH, all internal switches are turned OFF regardless of S1–S3 state, presenting high-impedance between Z and all Yn terminals. When E = LOW, channel selection proceeds normally per the 3-bit S1–S3 code. This allows global channel disable for safety interlocks or power-saving modes - a feature validated in Table 3 (Function table) and Fig. 1 (Functional diagram).
What is the typical ON-resistance mismatch (ΔRON) across channels for HEF4051BP,652?
The HEF4051BP,652 specifies ΔRON ≤ 5 Ω (typical) across all eight channels at 15 V supply and 25 °C, per Table 7. This tight matching ensures uniform gain and offset behavior when used in programmable resistor networks or PGA feedback paths - critical for applications like automatic calibration where channel-to-channel consistency directly impacts measurement accuracy.
Is HEF4051BP,652 qualified for automotive applications?
No, HEF4051BP,652 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" in Section 15 and confirms no AEC-Q100 testing or automotive-specific screening. While it operates from -40 °C to +125 °C - a range overlapping some automotive ambient conditions - it lacks automotive-grade reliability validation, PPAP documentation, and fault coverage required for safety-critical vehicle subsystems.
