Product details
Overview
MAX4667ESE+ from Maxim Integrated is a dual, normally closed (NC), single-pole single-throw (SPST) CMOS analog switch with 2.5Ω 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 ±20V. It delivers guaranteed RON matching ≤0.4Ω between channels and <5nA off-leakage at +85°C, making it suitable for precision reed relay replacement in automated test equipment and audio-signal routing.
For engineers reviewing the MAX4667ESE+ datasheet, MAX4667ESE+ pinout, MAX4667ESE+ application, or MAX4667ESE+ equivalent, key selection criteria include its NC-only topology, -40°C to +85°C industrial temperature rating, 16-pin narrow SO package, and TTL/CMOS-compatible logic thresholds (0.8V/2.4V) enabling direct interface with +12V or ±15V systems.
Technical Context
The MAX4667ESE+ implements two independent NC switches using high-voltage CMOS process technology, supporting symmetrical dual supplies (±4.5V to ±20V) or asymmetric single supplies (+4.5V to +36V). Its control logic is referenced to VL (logic supply), decoupled from analog rails, ensuring robust switching across wide common-mode ranges.
Each switch guarantees break-before-make is *not* implemented (distinct from MAX4669), and features matched on-resistance flatness ≤0.5Ω over full signal range (±20V), enabling low-distortion signal routing in DC-coupled instrumentation paths without gain or offset error introduced by resistance variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max at ±15V dual supply - ensures minimal voltage drop and power loss in signal paths carrying up to ±100mA continuous current. |
| RON Match (ΔRON) | 0.4Ω max - enables precise channel-to-channel gain tracking in differential or multiplexed measurement circuits. |
| Off-Leakage Current | 0.5nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and sample-and-hold stages. |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports legacy industrial ±15V systems and modern wide-range battery-powered designs. |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V - ensures reliable TTL/CMOS compatibility without level-shifting when driven from +5V or +12V microcontrollers. |
| Turn-On/Off Time | tON = 400ns, tOFF = 300ns (±15V, VCOM = ±10V) - enables fast multiplexing in data acquisition systems sampling at ≥1MHz. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field service without external protection. |
Pinout & Package
MAX4667ESE+ is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm body size, and exposed pad not present. Pin 1 is marked with a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Unbonded die pads; must be connected to GND for optimal off-isolation and EMI suppression. |
| 2, 7 | Digital Control Input (IN1, IN2) | Active-high logic inputs controlling respective NC switches; compatible with 0.8V/2.4V TTL/CMOS thresholds. |
| 4 | Negative Analog Supply (V−) | Reference for negative rail; tied to GND for single-supply operation (+4.5V to +36V). |
| 5 | Ground (GND) | Logic and substrate reference; requires low-impedance connection to minimize noise coupling into analog paths. |
| 9, 16 | Normally Closed Terminal (NC1, NC2) | Analog output nodes closed to COM when IN = low; open when IN = high - defines NC switching behavior. |
| 11, 14 | Common Terminal (COM1, COM2) | Analog input nodes; carry rail-to-rail signals (V− to V+) and support ±100mA continuous current. |
| 12 | Logic Supply (VL) | Independent 2.7V–5.5V logic rail; isolates digital switching noise from analog sections and enables mixed-voltage system interfacing. |
| 13 | Positive Analog Supply (V+) | Primary analog rail; supports up to +44V absolute max; must be powered before V− and logic inputs per sequencing guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output signals spanning V− to V+, enabling direct interface with op-amps, ADCs, and DACs operating at full supply rails. |
| Guaranteed RON flatness ≤0.5Ω | Maintains consistent gain and linearity across ±20V signal range - critical for precision DC-coupled instrumentation and calibration circuits. |
| TTL/CMOS-compatible logic inputs | Eliminates need for external level shifters when driving from standard microcontrollers or FPGAs operating at +5V or +12V. |
| Low 5nA max off-leakage at +85°C | Minimizes error in high-impedance sensor front-ends (e.g., thermocouples, pH electrodes) and long-time-constant integrators. |
| Industrial temperature range (−40°C to +85°C) | Validated performance across extended ambient conditions required for avionics, industrial PLCs, and outdoor test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4668ESE+ | Dual normally open (NO) topology instead of NC; identical RON, leakage, and supply specs. | Suitable where default-open signal paths are required (e.g., safety interlocks, default-disconnect sensors). | Select MAX4668ESE+ only if circuit logic requires active-low enable behavior or failsafe open state. |
| ADG1419BRUZ | Single-supply only (+5V to +36V); higher RON (4.7Ω typ); no dual-supply capability; different pinout. | Targeted at cost-sensitive industrial controls where ±15V rails are absent and moderate on-resistance is acceptable. | Choose ADG1419BRUZ only when dual-supply operation is unnecessary and PCB layout allows for non-pin-compatible footprint change. |
Compared with MAX4667ESE+, MAX4668ESE+ offers identical electrical performance but inverted switch logic (NO vs NC), requiring schematic and firmware updates; ADG1419BRUZ trades dual-supply flexibility and lower RON for simplified single-rail biasing and lower unit cost in non-military applications.

FAQ
What is the maximum analog signal voltage range supported by the MAX4667ESE+?
The MAX4667ESE+ supports rail-to-rail analog signals from V− to V+, with absolute maximum ratings of −44V to +44V on V+ and V− pins. Under normal operation with ±15V dual supplies, it handles ±20V signals across COM/NC terminals. For single-supply use, V− is tied to GND and signals swing from 0V to V+ (up to +36V), confirmed in Electrical Characteristics tables for both dual- and single-supply configurations.
Does the MAX4667ESE+ support break-before-make switching?
No, the MAX4667ESE+ does not support break-before-make operation. As stated in the General Description, only the MAX4669 variant guarantees break-before-make; the MAX4667ESE+ implements two independent normally closed (NC) switches with no timing coordination between them. This makes it unsuitable for applications requiring guaranteed isolation during state transitions, such as analog multiplexer channel switching where signal shorting must be avoided.
What is the purpose of the VL pin on the MAX4667ESE+?
The VL pin on the MAX4667ESE+ is the dedicated logic supply input, accepting 2.7V to 5.5V to power internal control circuitry independently from analog rails. This separation prevents digital switching noise from coupling into sensitive analog paths and enables interoperability with mixed-voltage systems-for example, using +3.3V logic to control ±15V analog signal routing. VL must be present before applying analog supplies per recommended power sequencing.
Can the MAX4667ESE+ be used with a single +12V supply?
Yes, the MAX4667ESE+ operates with a single +12V supply: connect V− to GND, V+ to +12V, and VL to +5V (or +3.3V). Electrical Characteristics tables confirm RON = 4Ω max, tON/tOFF ≤ 500ns, and leakage <0.5nA under these conditions. The device maintains rail-to-rail operation from 0V to +12V on COM/NC terminals, making it suitable for portable instrumentation and +12V automotive subsystems.
How is the MAX4667ESE+ protected against electrostatic discharge?
The MAX4667ESE+ features guaranteed ESD protection exceeding 2kV per Method 3015.7 (human-body model), as explicitly stated in the Features section and verified in production testing. This level of protection allows safe handling during PCB assembly and field maintenance without requiring additional external TVS diodes on control or analog pins under typical lab and industrial environments.
