Product details
Overview
HCF4051M013TR from STMicroelectronics is a single 8-channel analog multiplexer/demultiplexer IC in SO-16 package, featuring low ON resistance (125 Ω typ.), high OFF resistance (>1012 Ω), ±100 pA channel leakage (typ. at VDD–VEE = 18 V), and 3-bit binary address decoding with inhibit control. It operates across –55 °C to +125 °C and supports analog signal ranges up to 20 Vp-p with VDD–VEE = 15 V, used in automotive sensor signal routing and industrial data acquisition systems.
For engineers reviewing the HCF4051M013TR datasheet, HCF4051M013TR pinout, HCF4051M013TR application, or HCF4051M013TR equivalent, key selection criteria include guaranteed operation over –55/+125 °C, matched RON (5 Ω typ. mismatch), quiescent current ≤600 μA at 15 V, and SO-16 tape-and-reel packaging for automated assembly.
Technical Context
The HCF4051M013TR implements an 8:1 bidirectional analog switch matrix using MOS transmission gates controlled by three binary address inputs (A, B, C) and an active-high INH input. All eight channels share a common I/O terminal (COM), enabling both multiplexing and demultiplexing functions without external reconfiguration.
Its DC-coupled architecture supports rail-to-rail analog signals from VEE to VDD, with independent digital supply (VDD–VSS) and analog supply (VDD–VEE) domains. Quiescent power dissipation remains stable at 0.2 μW (typ.) regardless of control logic state, due to CMOS-only biasing and no static current paths through enabled switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| ON Resistance | 125 Ω (typ.) at VDD–VEE = 15 V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel Leakage | ±100 pA (typ.) at VDD–VEE = 18 V - enables high-impedance sensor interfacing without measurable offset drift |
| Signal Range | 20 Vp-p analog swing - supports full-range industrial transducer outputs without level-shifting circuitry |
| Quiescent Current | 600 μA max. at VDD = 20 V, TA = 125 °C - guarantees stable operation in thermally demanding under-hood environments |
| Propagation Delay | 120 ns (typ.) address-to-output at VDD–VEE = 15 V - enables reliable switching at >1 MHz sampling rates in data loggers |
| Distortion | <0.5 % THD (typ.) at 1 kHz, 5 Vpp, RL = 10 kΩ - preserves fidelity in audio and instrumentation signal chains |
| ESD Rating | HBM: 2 kV - meets basic handling robustness requirements for manual assembly and field service |
Pinout & Package
Package: SO-16 (Small Outline, 16-pin, 3.9 mm width, ECOPACK® compliant). Body dimensions: 9.8 × 5.8 mm, lead pitch 1.27 mm, typical thickness 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | Channel I/O (0–7) | Independent bidirectional analog terminals; each connects to COM when selected, otherwise isolated |
| 3 | COM (Common I/O) | Shared analog port for all 8 channels - serves as output during mux mode, input during demux mode |
| 6 | INH (Inhibit) | Active-high enable/disable control - forces all switches OFF when logic HIGH, overriding address inputs |
| 9, 10, 11 | A, B, C (Address Inputs) | 3-bit binary select lines - decode to activate exactly one channel per combination (000–111) |
| 7 | VEE | Negative analog supply rail - sets lower bound of analog signal range; must be ≤ VSS |
| 8 | VSS | Digital ground reference - defines logic '0' level and supplies internal CMOS logic core |
| 16 | VDD | Positive supply rail - powers both analog switches and digital decoder; supports 3–20 V operation |
Key Features
| Feature | Design Value |
|---|---|
| Matched RON | 5 Ω (typ.) mismatch between any two channels - ensures consistent gain and phase response across multiplexed sensor channels |
| Wide Supply Flexibility | VDD = 3–20 V, VDD–VEE = up to 18 V - allows direct interface with legacy ±12 V, ±15 V, or single-supply 5/12/24 V systems |
| Low Distortion | <0.5 % THD at 1 kHz - maintains signal integrity in audio monitoring and vibration analysis applications |
| Zero Static Power State | 0.2 μW (typ.) quiescent dissipation - eliminates thermal drift concerns in battery-powered remote sensors |
| High Channel Isolation | Feedthrough <12 mVp-p at 10 MHz - prevents crosstalk between adjacent channels in multi-signal telemetry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4051BE | Same pinout and function but PDIP-16 only; wider VDD range (3–20 V), higher RON (240 Ω typ. at 15 V), no AEC-Q100 qualification | Limited to commercial temperature range (–40/+85 °C); unsuitable for under-hood automotive use | Select for cost-sensitive prototyping where SO-16 footprint and extended temperature are not required |
| ADG1408BRUZ | CMOS process; lower RON (4.7 Ω typ.), faster switching (120 ns), but narrower analog range (±15 V), higher supply current (100 μA) | Requires dual ±15 V supplies; lacks inhibit pin; not rated beyond +85 °C | Prefer for high-speed, low-distortion lab equipment where precision outweighs temperature and supply flexibility |
Compared with CD4051BE and ADG1408BRUZ, the HCF4051M013TR uniquely combines automotive-grade temperature range (–55/+125 °C), SO-16 tape-and-reel packaging, integrated inhibit control, and 20 Vp-p analog capability - making it optimal for production-grade embedded systems requiring long-term reliability and supply chain stability.

FAQ
What is the maximum analog signal voltage the HCF4051M013TR can handle?
The HCF4051M013TR supports analog signals up to 20 Vp-p when VDD–VEE = 15 V, with absolute maximum ratings allowing VDD up to +22 V and VEE down to –0.5 V relative to VSS. Operation requires VEE ≤ VSS, and analog swing is bounded by VEE (lower) and VDD (upper), not VSS.
Does the HCF4051M013TR require external pull-up or pull-down resistors on address pins?
No. The A, B, C, and INH inputs have CMOS-compatible thresholds (VIL ≤ 1.5 V at VDD = 5 V; VIH ≥ 3.5 V at VDD = 5 V) and negligible input leakage (±0.1 μA max), so they interface directly with standard microcontroller GPIOs without external biasing components.
Can the HCF4051M013TR operate with VDD = 3.3 V and still switch analog signals up to 5 V?
No. The analog signal range is constrained by VEE and VDD rails. With VDD = 3.3 V and VSS = 0 V, the maximum analog signal is 0 V to 3.3 V unless VEE is negative. To pass 5 V signals, VDD must be ≥5 V and VEE ≤0 V (e.g., VDD = 5 V, VSS = 0 V, VEE = 0 V).
Is the HCF4051M013TR pin-compatible with the CD4051BE?
Yes - both share identical pin numbering and function mapping in SO-16 and PDIP-16 packages respectively. However, the HCF4051M013TR uses SO-16 while CD4051BE is PDIP-16; physical layout differs, but PCB footprint and signal routing remain functionally interchangeable with package adaptation.
