Product details
Overview
The MAX4558CSE+T from Analog Devices is an 8-channel analog multiplexer configured as a single 8-to-1 switch, operating from ±2V to ±6V dual supplies or +2V to +12V single supply, with rail-to-rail signal handling, 160Ω on-resistance (±5V), ±15kV HBM ESD protection, and 1nA off-leakage at +25°C - used in audio/video routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4558CSE+T datasheet, MAX4558CSE+T pinout, MAX4558CSE+T application, or MAX4558CSE+T equivalent, key selection criteria include guaranteed on-resistance matching (2Ω typ), break-before-make timing (4–15ns), low charge injection (2.4pC), high off-isolation (–96dB @50Ω), and compatibility with TTL/CMOS logic at +5V or ±5V supplies.
Technical Context
The MAX4558CSE+T implements a CMOS transmission-gate architecture with integrated bidirectional SCR-based ESD protection on all X/Y/Z and X_/Y_/Z_ pins, enabling robust ±15kV HBM and ±12kV IEC air-gap discharge immunity without latchup. Its digital control logic accepts TTL/CMOS-compatible thresholds (0.8V/2.4V) and drives internal level translators that switch VCC/VEE rails to gate analog paths.
It features rail-to-rail analog operation across its full supply range, with leakage currents fully specified over temperature (1nA off-leakage at +25°C, 10nA max at +85°C), and dynamic performance characterized for 300Ω/35pF loads: tON = 90–175ns, tOFF = 55–150ns, and tOPEN = 4–15ns - ensuring precise channel switching in time-critical signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Configuration | 8-to-1 single-pole multiplexer with common output (X) and eight inputs (X0–X7) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rail-flexible designs |
| On-Resistance (RON) | 160Ω max at ±5V - ensures minimal signal attenuation and gain error in precision analog paths |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor and DAC/ADC interface circuits |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - eliminates need for external TVS diodes in harsh environments |
| Switching Speed | tON = 90–175ns, tOFF = 55–150ns (300Ω/35pF) - enables reliable multiplexing in audio and medium-speed DAQ |
| Off-Isolation | –96dB at 100kHz (50Ω load) - prevents crosstalk between inactive channels in multi-signal systems |
Pinout & Package
MAX4558CSE+T is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm width, RoHS-compliant, with standard JEDEC MS-012AC footprint and thermal pad not required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–2, 4–5, 12–15 | Analog Inputs X0–X7 | Eight bidirectional analog signal terminals; interchangeable as input or output per rail-to-rail operation |
| 3 | Analog Output X | Common switched output node; connects to selected X0–X7 when ENABLE = low and address matches |
| 6 | Digital Enable (ENABLE) | Active-low global enable; pull high to disable all switches and force high-impedance state |
| 7 | Negative Supply (VEE) | Analog negative rail; tie to GND for single-supply operation (+2V to +12V) |
| 8 | Ground (GND) | Digital and substrate reference; must be low-impedance connection for ESD current return path |
| 9–11 | Digital Address Inputs C, B, A | 3-bit binary select lines (C=MSB); decode X0–X7 with standard truth table (L/L/L = X0) |
| 16 | Positive Supply (VCC) | Primary analog/digital supply; powers internal logic, level translators, and switch gates |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full-swing signals from VEE to VCC - eliminates clipping in audio, sensor, and DAC interfaces |
| Guaranteed RON match between channels | 2Ω typical variation - critical for matched-gain applications like differential signal routing or calibration paths |
| Low charge injection (2.4pC) | Minimizes voltage glitch on sampled-hold nodes and ADC inputs - improves acquisition accuracy |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V supply - interoperates directly with microcontrollers and FPGAs without level shifters |
| Break-before-make switching | 4–15ns guaranteed interval - prevents momentary shorting between input channels during address transitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | 40V max supply, 4.7Ω RON, 1.5pC charge injection, but only ±5.5kV HBM ESD rating | Lacks integrated ±15kV ESD protection - requires external protection in high-static environments | Select when ultra-low RON and wide supply range outweigh ESD hardening needs |
| TS5A3159DBVR | Single 2:1 SPDT, 0.75Ω RON, 0.45pC charge injection, ±4kV HBM, 5-pin SOT-23 package | Not functionally equivalent - different topology (SPDT vs. 8:1), smaller channel count, lower ESD rating | Choose only for space-constrained 2-channel routing where MAX4558CSE+T's 8-channel density is unnecessary |
Compared with ADG1408BRUZ and TS5A3159DBVR, the MAX4558CSE+T uniquely delivers 8:1 multiplexing with factory-tested ±15kV HBM ESD protection and rail-to-rail operation down to +2V supply - making it optimal for compact, rugged, low-voltage signal routing where channel density and ESD resilience are co-critical.

FAQ
What supply voltages does the MAX4558CSE+T support?
The MAX4558CSE+T operates from dual supplies of ±2V to ±6V or a single supply of +2V to +12V. At ±5V, it achieves 160Ω typical on-resistance and full rail-to-rail analog signal handling. The device guarantees functionality across its entire rated range, including low-voltage operation down to +2V - ideal for coin-cell or Li-ion powered systems where the MAX4558CSE+T maintains signal fidelity without external level shifting.
Does the MAX4558CSE+T require external ESD protection?
No, the MAX4558CSE+T does not require external ESD protection. It integrates on-chip bidirectional SCRs on all X/Y/Z and X_/Y_/Z_ pins, delivering ±15kV Human Body Model (HBM), ±12kV IEC 1000-4-2 air-gap, and ±8kV contact discharge protection. This eliminates the need for discrete TVS diodes in end equipment, reducing BOM count and PCB area - a key advantage confirmed in the MAX4558CSE+T datasheet's ESD Test Conditions section.
How many analog channels does the MAX4558CSE+T support?
The MAX4558CSE+T supports one 8-to-1 analog multiplexer channel, with eight bidirectional analog inputs (X0–X7) and one common output (X). Its pinout and truth table confirm exclusive selection of one input per address (CBA), and no internal channel splitting or dual-path capability - unlike the MAX4559 (dual 4-to-1) or MAX4560 (triple SPDT). This makes the MAX4558CSE+T optimal for centralized signal routing where a single high-density switch suffices.
What is the maximum leakage current specification for the MAX4558CSE+T?
The MAX4558CSE+T specifies 1nA maximum off-leakage current at +25°C and 10nA maximum at +85°C, measured across X_/X terminals under worst-case bias conditions (VCC = +5.5V, VEE = –5.5V). This leakage is fully production-tested per datasheet Note 5 and directly impacts high-impedance applications such as sensor front-ends and sample-and-hold circuits - where the MAX4558CSE+T's low leakage preserves DC accuracy and settling time.
Is the MAX4558CSE+T pin-compatible with industry-standard logic ICs?
Yes, the MAX4558CSE+T is pin-compatible with the 74HC4051 analog multiplexer, sharing identical pin assignments for VCC, GND, ENABLE, address lines (A/B/C), common output (X), and analog inputs (X0–X7). This allows drop-in replacement in existing designs using the 74HC4051, while delivering superior performance: lower on-resistance (160Ω vs. ~120Ω typ for 74HC4051 at +5V), ±15kV ESD protection (vs. none), and guaranteed rail-to-rail operation - all within the same 16-pin narrow SOIC footprint of the MAX4558CSE+T.
