Product details
Overview
MAX4667EPE from Maxim Integrated is a dual SPST analog switch with two normally closed (NC) channels, designed for rail-to-rail signal routing in precision analog systems. It delivers 2.5Ω max on-resistance, 0.5Ω max RON match between channels, and 5nA max off-leakage at +85°C, enabling low-distortion reed relay replacement in test equipment and avionics.
For engineers reviewing the MAX4667EPE datasheet, MAX4667EPE pinout, MAX4667EPE application, or MAX4667EPE equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to MAX4667), dual-supply ±4.5V to ±20V operation, TTL/CMOS-compatible logic thresholds, and 16-pin plastic DIP packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The MAX4667EPE implements CMOS transmission-gate architecture with matched P- and N-channel devices per switch, ensuring flat on-resistance (≤0.5Ω variation) across ±10V signal range under ±15V supplies. Its dual NC topology enables fail-safe signal path closure during power loss or logic fault conditions.
Control inputs accept 0.8V/2.4V TTL/CMOS thresholds independent of supply voltage, supporting interoperability with +12V single-supply or ±15V dual-supply systems. Internal ESD protection exceeds 2kV per MIL-STD-883 Method 3015.7 without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 0.5Ω max - guarantees matched gain/phase response in differential or dual-path circuits |
| Off-Leakage Current | 5nA max at +85°C - preserves high-impedance node integrity in sensor front-ends and sample-hold stages |
| Supply Range | ±4.5V to ±20V dual or +4.5V to +36V single - supports wide-range industrial and aerospace power architectures |
| Turn-On/Off Time | 400ns / 300ns typical - enables reliable switching in audio routing and automated test sequencing |
| Rail-to-Rail Signal Handling | VCOM, VNC = V− to V+ - allows full-swing AC/DC signals without clipping or distortion |
| ESD Protection | >2kV per MIL-STD-3015.7 - eliminates need for external transient suppression in board-level designs |
Pinout & Package
MAX4667EPE uses a 16-pin plastic DIP package (PDIPN) with 0.3-inch body width and standard through-hole footprint. Pin 1 is top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8, 10, 15 | No Connect (N.C.) | Unbonded die pads; connect to GND for improved off-isolation and noise immunity |
| 2, 7 | IN1, IN2 | Digital control inputs - active-high logic closes respective NC switch |
| 4 | V− | Negative analog supply - tie to GND for single-supply operation |
| 5 | GND | Analog/digital reference ground - star-point connection required for low-noise performance |
| 9, 16 | NC1, NC2 | Normally closed analog terminals - conduct to COM when IN = low |
| 11, 14 | COM1, COM2 | Common analog ports - bidirectional signal path shared with NC/NO terminals |
| 12 | VL | Logic supply input - decoupled +5V source stabilizes input threshold behavior |
| 13 | V+ | Positive analog supply - sets upper rail for rail-to-rail signal handling |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RON flatness | ≤0.5Ω variation over ±10V signal range - maintains linearity in audio and instrumentation amplifiers |
| Dual NC configuration | Fail-closed default state - ensures continuity in safety-critical monitoring loops during controller reset |
| TTL/CMOS-compatible inputs | +0.8V/+2.4V thresholds with ±15V supplies - eliminates level-shifter ICs in mixed-voltage systems |
| Low charge injection | 450pC typical - minimizes glitch-induced error in sample-and-hold and multiplexer applications |
| High off-isolation | −60dB at 1MHz - suppresses crosstalk between adjacent signal paths in dense PCB layouts |
Applications

IC Role / Device Role / Timing Role: Rail-to-rail analog switch handling ±10V line-level signals with matched RON to preserve stereo balance. Use Value: 0.5Ω RON match ensures <0.02dB channel gain mismatch; flat RON prevents harmonic distortion across 20Hz–20kHz bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +36V); 2.1Ω RON; no dual NC variant | Requires redesign for dual NC functionality; superior RON flatness (0.2Ω) but lacks guaranteed break-before-make | Select when single-supply operation dominates and lower RON outweighs NC topology requirement |
| TS5A23159DRCR | Lower voltage range (2.5V to 5.5V); 0.9Ω RON; SC-70-6 package | Not suitable for ±15V systems; optimized for portable battery-powered audio, not industrial test gear | Choose only for space-constrained low-voltage consumer audio designs |
Compared with ADG1419BRUZ and TS5A23159DRCR, the MAX4667EPE uniquely combines dual NC topology, ±20V dual-supply operation, and guaranteed RON matching-making it irreplaceable in fail-safe industrial and avionics signal routing where power-loss continuity and high-voltage compatibility are mandatory.

FAQ
What is the maximum allowable supply voltage for MAX4667EPE?
The MAX4667EPE supports absolute maximum ratings of V+ to GND = −0.3V to +44V and V− to GND = +0.3V to −44V. For reliable operation, use within the specified dual-supply range of ±4.5V to ±20V or single-supply range of +4.5V to +36V. Exceeding these limits risks permanent damage, even briefly.
Does MAX4667EPE support break-before-make switching?
No, the MAX4667EPE does not provide guaranteed break-before-make operation. That feature is exclusive to the MAX4669 variant. The MAX4667EPE has two normally closed switches with independent control; simultaneous toggling may cause momentary shorting if both inputs transition concurrently without external timing control.
Can MAX4667EPE operate from a single +12V supply?
Yes, the MAX4667EPE operates from a +12V single supply with V− tied to GND. In this configuration, RON increases to 4Ω max (vs. 2.5Ω max under ±15V), and signal range is limited to 0V to +12V. Logic inputs remain TTL/CMOS-compatible via VL = +5V.
What is the thermal performance of MAX4667EPE in plastic DIP package?
The MAX4667EPE in 16-pin plastic DIP has a thermal resistance θJA of 95°C/W and a maximum continuous power dissipation of 842mW at +70°C ambient. Derating is 10.53mW/°C above +70°C. For sustained 100mA switching, keep ambient below +65°C or add copper pour heatsinking.
How does MAX4667EPE handle ESD events on analog pins?
The MAX4667EPE incorporates internal ESD protection diodes on all analog pins (COM, NC, NO, V+, V−) rated to >2kV per MIL-STD-883 Method 3015.7. These diodes clamp transients to V+ and V− rails; ensure external supply bypassing and avoid exceeding ±44V differential across V+ and V− to prevent latch-up.
