Product details
Overview
MAX4604ESE+ from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 5Ω max on-resistance, 0.5Ω max RON match between channels, and 2.5nA max off-leakage at +85°C, enabling low-distortion audio-signal routing and reed-relay replacement in test equipment.
For engineers reviewing the MAX4604ESE+ datasheet, MAX4604ESE+ pinout, MAX4604ESE+ application, or MAX4604ESE+ equivalent, key selection criteria include guaranteed RON flatness (0.5Ω max), dual-supply operation (±4.5V to ±20V), TTL/CMOS-compatible logic thresholds, and 16-pin narrow SO package compatibility with industrial temperature range (-40°C to +85°C).
Technical Context
The MAX4604ESE+ implements a CMOS-based quad SPST switch architecture with independent NC topology per channel, supporting both single-supply (+4.5V to +36V) and dual-supply (±4.5V to ±20V) operation. Its logic inputs feature fixed +0.8V / +2.4V thresholds, ensuring interoperability with TTL/CMOS drivers across supply configurations.
Each channel maintains rail-to-rail analog signal handling capability, with on-resistance flatness tightly controlled to ≤0.5Ω over the full specified signal range (±10V with dual supplies, 0–10V with single supply). Internal ESD protection exceeds 2000V per Method 3015.7, and leakage currents are fully tested at maximum hot temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths |
| RON Match | 0.5Ω max - enables matched gain/attenuation across channels in differential or multi-path systems |
| RON Flatness | 0.5Ω max - preserves linearity and THD performance over full input signal swing |
| Off-Leakage Current | 2.5nA max at +85°C - critical for high-impedance sensor interfaces and low-power standby modes |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial and test-equipment rails |
| Logic Thresholds | +0.8V low / +2.4V high - guarantees reliable TTL/CMOS compatibility without level-shifting circuitry |
| Turn-On/Off Time | 120ns / 130ns typical - suitable for medium-speed multiplexing up to ~1MHz switching rates |
Pinout & Package
MAX4604ESE+ is housed in a 16-pin narrow SOIC (SO/DIP) package with standard 1.27mm pitch, rated for -40°C to +85°C operation. The package provides thermal and mechanical reliability for industrial PCB layouts while maintaining compact footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; active-low logic sense for NC configuration |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connected to load/sensor side of each switch |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = 0V |
| 4 | V− | Negative analog supply - tied to GND for single-supply use |
| 5 | GND | Digital ground reference for logic and VL supply |
| 12 | VL | Logic supply input - accepts 3V to 5V for TTL/CMOS interface compatibility |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - essential for full-scale instrumentation and audio routing |
| Guaranteed RON match | ≤0.5Ω max mismatch between any two channels - enables precise channel-to-channel tracking in multi-channel systems |
| ESD protection | >2000V per Method 3015.7 - reduces need for external protection in board-level ESD-prone environments |
| Low charge injection | 225pC typical - minimizes transient glitches during switching in sample-and-hold or data-acquisition circuits |
| Low off-isolation degradation | -62dB typical at DC–1MHz - maintains signal integrity in adjacent channel routing applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG467BRZ | 5.5Ω max RON, ±20V dual-supply only, no single-supply support | Lacks +4.5V–+36V single-supply flexibility; requires dual-rail design | Select when system already uses ±15V rails and needs ADI's enhanced ESD rating (4kV HBM) |
| TS5A3157DCKR | 0.75Ω max RON, but limited to +1.65V–+5.5V supply and ±5.5V signal range | Not suitable for industrial/high-voltage signal routing; restricted to low-voltage portable systems | Prefer for battery-powered audio accessories where ultra-low RON outweighs voltage range limitations |
Compared with ADG467BRZ and TS5A3157DCKR, the MAX4604ESE+ uniquely combines wide supply flexibility (single or dual), guaranteed RON flatness, and industrial temperature rating - making it the only option among the three qualified for reed-relay replacement in ATE and avionics signal conditioning.

FAQ
What is the operating temperature range of the MAX4604ESE+?
The MAX4604ESE+ is rated for industrial operation from -40°C to +85°C. This range is validated per the manufacturer's qualification testing and applies to all electrical specifications in the datasheet, including on-resistance, leakage current, and switching times. The MAX4604ESE+ maintains guaranteed 5Ω max RON and 2.5nA max off-leakage across this full range, making it suitable for harsh-environment deployments where thermal stability is critical.
Does the MAX4604ESE+ support single-supply operation?
Yes, the MAX4604ESE+ supports single-supply operation from +4.5V to +36V. In this mode, V− is connected to GND, and analog signals swing from 0V to V+. The device retains rail-to-rail capability, 5Ω max RON, and TTL/CMOS-compatible logic thresholds (0.8V/2.4V) - eliminating need for level shifters. This configuration is widely used in programmable logic controllers and industrial I/O modules.
How does the MAX4604ESE+ differ from the MAX4605ESE+?
The MAX4604ESE+ features four normally closed (NC) switches, whereas the MAX4605ESE+ has four normally open (NO) switches. Their pinouts and electrical specs are identical except for logic polarity: for MAX4604ESE+, IN = 0V closes the switch; for MAX4605ESE+, IN = 0V opens it. Both share the same RON, leakage, and supply specifications - selection depends solely on fail-safe state requirement in the target system.
What is the purpose of the VL pin on the MAX4604ESE+?
The VL pin on the MAX4604ESE+ supplies power to the internal logic circuitry and sets the reference for digital input thresholds. It accepts 3V to 5V and must be decoupled locally. Unlike V+ and V−, VL is independent of analog supply rails - allowing clean logic interfacing even when analog supplies are noisy or asymmetric. This separation prevents digital noise from coupling into sensitive analog paths in the MAX4604ESE+.
Can the MAX4604ESE+ handle bipolar analog signals?
Yes, the MAX4604ESE+ handles bipolar analog signals when operated from dual supplies (±4.5V to ±20V). With V+ = +15V and V− = -15V, it passes signals from -15V to +15V rail-to-rail with 5Ω max RON and <0.5Ω flatness. This capability is confirmed in the datasheet's dual-supply electrical characteristics table and typical curves, making the MAX4604ESE+ suitable for op-amp signal routing and sensor interfaces requiring true bipolar operation.
