Product details
Overview
MAX4604EPE+ from Maxim Integrated is a quad, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch with 5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±10V. It delivers 0.5Ω max on-resistance matching and flatness, 2.5nA max off-leakage at +85°C, and is used in reed relay replacement, PBX systems, and automated test equipment.
For engineers reviewing the MAX4604EPE+ datasheet, MAX4604EPE+ pinout, MAX4604EPE+ application, or MAX4604EPE+ equivalent, key selection criteria include NC-switch topology, 16-pin PDIP package, -40°C to +85°C temperature grade, TTL/CMOS-compatible logic thresholds, and guaranteed ESD protection >2000V.
Technical Context
The MAX4604EPE+ implements four independent SPST switches with normally closed configuration-each COM terminal connects to its NC terminal when the control input is logic low. Its CMOS architecture enables rail-to-rail analog signal switching across the full supply range without distortion or clipping.
It features matched and flat on-resistance (≤0.5Ω variation across channels and signal range), dual- or single-supply flexibility, and logic inputs referenced to VL (5V) with fixed TTL/CMOS thresholds (0.8V/2.4V), ensuring robust digital interface behavior even under ±15V analog supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 5Ω max - ensures minimal voltage drop and power loss in signal paths up to ±10V. |
| RON Match | 0.5Ω max - guarantees channel-to-channel gain/attenuation consistency in multi-path routing. |
| RON Flatness | 0.5Ω max over signal range - preserves linearity and THD in audio and precision instrumentation. |
| Off-Leakage Current | 2.5nA max at +85°C - enables high-impedance sensor or reference signal switching without loading error. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports industrial, avionics, and telecom voltage rails. |
| Logic Thresholds | 0.8V low / 2.4V high - ensures reliable TTL/CMOS compatibility without level-shifting circuitry. |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling during board assembly and system integration. |
Pinout & Package
MAX4604EPE+ is housed in a 16-pin plastic DIP (PDIP) package with 0.3-inch body width, through-hole mounting, and industry-standard pin spacing for manual or wave-solder assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs; logic low closes all four NC switches. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - connect to signal source or load. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = low. |
| 4 | V− | Negative analog supply rail; tied to GND for single-supply use. |
| 5 | GND | Digital ground reference for logic and VL supply. |
| 12 | VL | Logic supply input - must be 5V for specified TTL/CMOS thresholds. |
| 13 | V+ | Positive analog supply rail - sets upper signal swing limit. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ (e.g., ±15V or 0V to +12V), eliminating clipping in wide-dynamic-range systems. |
| Guaranteed RON match | ≤0.5Ω difference between any two channels - critical for balanced multiplexing and differential signal routing. |
| Low charge injection (10pC typ) | Minimizes transient glitches and settling errors in sample-and-hold or data-acquisition front-ends. |
| High off-isolation (−62dB typ) | Prevents crosstalk between active and inactive signal paths in dense routing applications like test fixtures. |
| TTL/CMOS-compatible inputs | Operates reliably with standard microcontroller GPIOs or FPGA outputs without external biasing or level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4604ESE+ | Narrow SO-16 package (surface-mount); identical electrical specs and NC topology. | Preferred for automated SMT assembly; requires PCB redesign vs. through-hole MAX4604EPE+. | Select MAX4604ESE+ when board space, thermal performance, or production scalability are priorities. |
| ADG1404BRUZ | Quad SPST, NC; 4.7Ω max RON; ±15V supply; but requires VL = VDD and lacks guaranteed RON flatness spec. | Better THD in audio paths; no guaranteed 0.5Ω flatness - less suitable for precision instrumentation calibration. | Choose ADG1404BRUZ only if SOIC-16 footprint and lower RON outweigh need for flatness guarantee and PDIP compatibility. |
Compared with MAX4604ESE+, the MAX4604EPE+ offers direct through-hole assembly and identical performance, while ADG1404BRUZ trades guaranteed flatness and package compatibility for marginally lower RON and different logic supply architecture.

FAQ
What is the logic configuration of the MAX4604EPE+?
The MAX4604EPE+ implements four normally closed (NC) SPST analog switches: each COM pin conducts to its corresponding NC pin when the associated IN pin is logic low (≤0.8V). When IN is high (≥2.4V), the switch opens. This behavior is confirmed in the truth table and functional diagrams of the MAX4604EPE+ datasheet.
Does the MAX4604EPE+ support single-supply operation?
Yes, the MAX4604EPE+ operates from a single supply of +4.5V to +36V. In this mode, V− is connected to GND, V+ supplies the positive rail, and VL is biased at 5V. All electrical characteristics-including 5Ω max on-resistance and 2.5nA off-leakage-are fully specified and guaranteed under single-supply conditions.
What is the role of the VL pin on the MAX4604EPE+?
The VL pin on the MAX4604EPE+ sets the reference voltage for the digital logic inputs and must be connected to a stable 5V supply. It defines the 0.8V/2.4V TTL/CMOS-compatible input thresholds and remains independent of analog supply voltages (V+ and V−), enabling robust interfacing with 3.3V or 5V controllers even under ±15V analog operation.
Can the MAX4604EPE+ handle bipolar analog signals?
Yes, the MAX4604EPE+ supports true bipolar signal routing: it operates with dual supplies from ±4.5V to ±20V and handles rail-to-rail analog signals spanning V− to V+, including ±10V, ±15V, and asymmetric ranges. The internal ESD protection diodes clamp signals beyond rails, and absolute maximum ratings confirm safe operation with VCOM, VNC, or VNO extending to ±10V relative to GND.
Is the MAX4604EPE+ pin-compatible with other variants in the MAX4604/MAX4605/MAX4606 family?
Yes, the MAX4604EPE+ shares identical pinout and package (16-pin PDIP) with MAX4605EPE+ and MAX4606EPE+. However, their switch configurations differ: MAX4604EPE+ is quad NC, MAX4605EPE+ is quad NO, and MAX4606EPE+ is dual NC/dual NO. Swapping them requires logic inversion or firmware changes to maintain correct signal routing behavior.
