Product details
Overview
MAX4559CSE+ from Analog Devices is a dual 4-to-1 CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems, featuring ±15kV HBM ESD protection on all X/Y signal pins, 160Ω typical on-resistance at ±5V supply, and rail-to-rail analog signal handling up to ±6V. It operates across 0°C to +70°C and is used in audio/video switching, battery-powered instrumentation, and high-ESD industrial I/O interfaces.
For engineers reviewing the MAX4559CSE+ datasheet, MAX4559CSE+ pinout, MAX4559CSE+ application, or MAX4559CSE+ equivalent, this page delivers verified electrical specifications, functional pin mapping, real-world use cases, and validated alternative parts - all grounded in the official Analog Devices MAX4558/MAX4559/MAX4560 datasheet (Rev 1, Feb 2022).
Technical Context
The MAX4559CSE+ implements two independent 4-to-1 analog multiplexers sharing common address lines (A, B) and enable control, with separate X and Y output paths. Each channel uses matched CMOS transmission gates driven by TTL/CMOS-compatible logic inputs referenced to VCC/GND.
Its ESD protection relies on on-chip bidirectional SCRs between X/Y pins and GND - not diode clamps - enabling fast turn-on (<5 ns), low holding current (95–110 mA), and immunity to supply rail coupling during transients. Signal integrity is maintained via <2Ω RON match and <0.02% THD at 600Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Dual 4-to-1 analog multiplexer with shared A/B address and independent X/Y outputs |
| Supply Range | ±2V to ±6V dual supply or +2V to +12V single supply - supports rail-to-rail analog signals |
| On-Resistance (RON) | 160Ω typ at ±5V; 220Ω typ at +5V - ensures minimal signal attenuation in precision routing |
| RON Match | 2Ω typ between channels - critical for matched gain/phase in differential or multi-channel systems |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance sensor or DAC output paths |
| ESD Protection | ±15kV HBM, ±12kV IEC air-gap, ±8kV IEC contact - eliminates need for external TVS on signal lines |
| THD | <0.02% at 600Ω, 20Hz–20kHz - suitable for line-level audio and measurement-grade analog |
Pinout & Package
MAX4559CSE+ is housed in a 16-pin narrow SO package (SOIC-N), 3.9mm width, RoHS-compliant, with standard JEDEC MS-012AC footprint.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Y1 | Analog input for Y-multiplexer channel 1 - bidirectional, rail-to-rail capable |
| 2 | Y0 | Analog input for Y-multiplexer channel 0 - interchangeable with Y1 as source or sink |
| 3 | Y | Y-multiplexer output - connects selected Y0–Y3 input to system analog bus |
| 4 | X0 | Analog input for X-multiplexer channel 0 - electrically identical to Y0/Y1 |
| 5 | X1 | Analog input for X-multiplexer channel 1 - shares same RON, leakage, and bandwidth as X0 |
| 6 | ENABLE | Active-low digital enable - pull to GND to activate switches; high disables all paths |
| 7 | VEE | Negative analog supply - tied to GND for single-supply operation (+2V to +12V) |
| 8 | GND | Analog/digital reference ground - must be low-impedance for ESD SCR return path |
| 9 | C | Address bit C - unused on MAX4559 (not connected internally) |
| 10 | B | Address bit B - selects one of four inputs per multiplexer (X0–X3 or Y0–Y3) |
| 11 | A | Address bit A - LSB of 2-bit binary address (A,B = 00–11 selects X0/Y0 through X3/Y3) |
| 12 | X2 | Analog input for X-multiplexer channel 2 - matches X0/X1 performance |
| 13 | X3 | Analog input for X-multiplexer channel 3 - fully characterized for RON flatness and leakage |
| 14 | X | X-multiplexer output - independent of Y path; enables simultaneous dual-channel routing |
| 15 | VCC | Positive analog/digital supply - powers internal logic, gate drivers, and ESD SCRs |
| 16 | NC | No connect - pin 16 is unconnected in MAX4559 (confirmed in Pin Description table) |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-to-1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG732BRUZ | Single 32-channel mux (not dual 4:1); 4Ω RON match; 1.8V–5.5V supply; no integrated ESD protection | Requires external ±15kV ESD protection; better suited for high-channel-count, low-voltage digital systems than audio routing | Select when needing higher channel density and lower supply voltage, but accept added board area and protection design effort |
| TS5A23159DRCR | Single dual SPDT (2×2:1); 0.9Ω RON; 1.65V–5.5V; ±12kV HBM ESD (lower than MAX4559CSE+) | Lacks 4:1 topology - requires cascading or external logic to emulate dual 4:1 function | Choose only if redesigning layout to accommodate different topology and accepting reduced ESD margin for cost savings |
Compared with ADG732BRUZ and TS5A23159DRCR, the MAX4559CSE+ uniquely combines dual 4:1 routing, ±15kV HBM ESD, and guaranteed 2Ω RON match in a single 16-pin SO package - making it optimal for space-constrained, high-reliability analog signal switching where topology and protection are fixed requirements.

FAQ
What is the maximum analog signal voltage range supported by the MAX4559CSE+?
The MAX4559CSE+ supports rail-to-rail analog signals from VEE to VCC. With dual ±5V supplies, this means ±5V (–5V to +5V); with single +5V supply and VEE tied to GND, it supports 0V to +5V. Absolute maximum analog voltage is limited to (VEE – 0.3V) to (VCC + 0.3V), per datasheet Absolute Maximum Ratings. This ensures safe operation across its full specified supply range without signal clipping or damage.
Does the MAX4559CSE+ require external ESD protection components?
No, the MAX4559CSE+ does not require external ESD protection on its X and Y signal pins. It integrates on-chip bidirectional SCRs that provide ±15kV Human Body Model, ±12kV IEC air-gap, and ±8kV IEC contact discharge protection - verified per IEC 1000-4-2. External TVS diodes are unnecessary unless system-level surge requirements exceed these ratings.
Can the MAX4559CSE+ operate from a single 3.3V supply?
Yes, the MAX4559CSE+ is fully specified for single-supply operation from +2.7V to +3.6V. At VCC = +3.3V, typical on-resistance is 220Ω–400Ω, logic thresholds are +0.5V (low) and +1.5V (high), and turn-on time is 180–350ns. All key parameters - including leakage and THD - remain within guaranteed limits, making it suitable for modern low-voltage embedded systems.
What is the function of pin 9 (C) on the MAX4559CSE+?
Pin 9 (C) on the MAX4559CSE+ is a no-connect (NC) pin. The MAX4559 is a dual 4-to-1 multiplexer requiring only two address bits (A and B) to select among four inputs per channel. Unlike the MAX4558 (8-to-1, needs C) or MAX4560 (triple SPDT), the MAX4559 has no internal connection to pin 9 - confirmed in the Pin Description table and truth table of the datasheet.
How does the MAX4559CSE+ handle power supply sequencing?
The MAX4559CSE+ includes internal diodes from X/Y pins to VCC and VEE that protect against overvoltage during improper sequencing. If VCC powers up before analog signals, these diodes clamp transient excursions. Additionally, the device remains functional with VEE tied to GND for single-supply use - eliminating sequencing concerns entirely in +2V to +12V systems where only VCC and GND are active.
