Product details
Overview
MAX4679EPE+ from Analog Devices is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring guaranteed break-before-make switching, 1.6Ω max on-resistance at ±5V dual supply, 0.3Ω max RON matching, and rail-to-rail signal handling - ideal for precision audio routing and automated test equipment signal path control.
For engineers reviewing the MAX4679EPE+ datasheet, MAX4679EPE+ pinout, MAX4679EPE+ application, or MAX4679EPE+ equivalent, this page delivers verified electrical specs, true pin-function mapping for the 16-pin DIP package, confirmed break-before-make timing (5ns), leakage performance (0.1nA @ +25°C), and validated alternatives for reed relay replacement and low-distortion analog switching.
Technical Context
The MAX4679EPE+ implements four independent CMOS SPST switches in a single monolithic die, with dedicated NO/NC topology per channel pair (switches 1 & 4 = NO; 2 & 3 = NC). Its break-before-make behavior is guaranteed via internal logic sequencing - not inferred - and applies only to the MAX4679 variant, not MAX4677/MAX4678.
It supports dual ±2.7V to ±5.5V or single +2.7V to +11V operation, with a separate VL pin enabling independent logic supply (2.7V to V+) - critical for mixed-voltage system interfacing. Signal bandwidth reaches 66MHz (-3dB) under dual-supply conditions, with -84dB crosstalk and -65dB off-isolation at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 1.6Ω max at ±5V, ensuring minimal voltage drop and power loss in precision analog paths (e.g., <0.08mV error at 50mA). |
| RON Matching | 0.3Ω max between channels, enabling matched gain/attenuation in differential or multi-channel instrumentation. |
| Break-Before-Make Delay | 5ns guaranteed (RL=300Ω, CL=35pF), preventing momentary short-circuits during channel switching in multiplexed systems. |
| Off-Leakage Current | 0.1nA max at +25°C, preserving signal integrity in high-impedance sensor front-ends and ADC sample-hold circuits. |
| -3dB Bandwidth | 66MHz under dual ±5V supply, supporting video-rate and wideband communication signal routing without attenuation. |
| Crosstalk | -84dB at 1MHz, minimizing unintended coupling between adjacent switched channels in dense PCB layouts. |
| Supply Range | Dual ±2.7V to ±5.5V or single +2.7V to +11V, enabling direct compatibility with legacy ±5V systems and modern 3.3V/5V logic domains. |
Pinout & Package
MAX4679EPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin pitch is 0.1 inch; lead finish is lead-free (RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL-compatible logic inputs controlling switch state; referenced to VL, not GND or V+. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path junctions connecting to NO or NC based on logic state. |
| 3, 6 | NO1, NO4 | Normally open analog terminals - conduct only when corresponding IN = logic high (MAX4679-specific assignment). |
| 11, 14 | NC2, NC3 | Normally closed analog terminals - conduct when corresponding IN = logic low (MAX4679-specific assignment). |
| 4 | V− | Negative supply input; connect to GND for single-supply operation; absolute max rating: −12V. |
| 5 | GND | Ground reference for logic and substrate; must be low-impedance return path for analog signals. |
| 12 | VL | Independent logic supply input (2.7V to V+); decouples logic threshold from analog rail noise. |
| 13 | V+ | Positive supply input; supports up to +12V absolute max; powers analog switch core and level shifters. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | 5ns minimum delay prevents signal shorting during channel transitions - essential for fault-tolerant multiplexers. |
| Rail-to-rail analog signal range | Supports full V− to V+ swing (e.g., −5V to +5V), eliminating clipping in bipolar sensor interfaces and audio line drivers. |
| Low on-resistance flatness (0.4Ω max) | Ensures consistent gain/attenuation across entire signal range - critical for measurement accuracy in data acquisition. |
| TTL/CMOS logic compatibility | VIH = 2.4V min, VIL = 0.8V max at VL = V+, enabling direct interface with 3.3V or 5V microcontrollers without level shifters. |
| −84dB crosstalk at 1MHz | Reduces inter-channel interference in multi-signal routing applications like PBX voice switching or multi-channel ADC front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4679EUE+ | Same electrical specs and function, but in 16-pin TSSOP (4.4mm × 5mm) instead of 16-pin DIP (19.1mm × 6.6mm). | Preferred for space-constrained PCBs; requires reflow soldering and different land pattern. | Select EUE+ for compact SMT designs; EPE+ for through-hole prototyping, legacy repair, or high-vibration environments. |
| ADG1419BRUZ | Quad SPST, 1.3Ω RON, ±5V/±15V capable, but no guaranteed break-before-make; higher 0.5nA leakage at +25°C. | Better for high-voltage industrial I/O; unsuitable where BbM is mandatory (e.g., hot-swap signal routing). | Choose ADG1419BRUZ only if lower RON outweighs need for guaranteed BbM; verify timing requirements in final layout. |
Compared with MAX4679EPE+, the MAX4679EUE+ offers identical functionality in a smaller footprint but requires SMT assembly, while ADG1419BRUZ trades guaranteed break-before-make for wider supply range and marginally lower RON - making EPE+ optimal for legacy DIP-based ATE and audio hardware requiring assured switching safety.

FAQ
What is the guaranteed break-before-make timing specification for MAX4679EPE+?
The MAX4679EPE+ guarantees a minimum break-before-make delay of 5ns under RL = 300Ω and CL = 35pF conditions, as measured per Figure 3 in the official Analog Devices datasheet. This parameter is unique to the MAX4679 variant and is not specified for MAX4677 or MAX4678. The timing ensures no overlap between NC and NO conduction states, preventing shorts in critical signal routing paths. MAX4679EPE+ maintains this guarantee across its full operating temperature range (−40°C to +85°C).
Does MAX4679EPE+ support single-supply operation, and what is the minimum V+ voltage?
Yes, MAX4679EPE+ supports single-supply operation from +2.7V to +11V on V+, with V− tied to GND. The absolute minimum V+ is +2.7V - below which RON exceeds specification (e.g., >3.5Ω typical at +2.7V). At +2.7V, the device remains fully functional with TTL/CMOS-compatible logic thresholds (VIH = 2.4V, VIL = 0.8V) when VL is set to V+. Performance metrics such as bandwidth (63MHz) and leakage (0.1nA) remain valid within this range.
What is the maximum allowable voltage difference between V+ and V− for MAX4679EPE+?
The absolute maximum voltage difference between V+ and V− for MAX4679EPE+ is +12V, as stated in the Absolute Maximum Ratings table. Exceeding this limit risks permanent damage. For reliable operation, Analog Devices specifies dual-supply operation from ±2.7V to ±5.5V - meaning V+ = +5.5V and V− = −5.5V yields an 11V differential, staying within the 12V safety margin. This allows use in standard ±5V systems with 10% tolerance.
Can MAX4679EPE+ drive rail-to-rail signals when powered by a single +5V supply?
Yes, MAX4679EPE+ supports rail-to-rail analog signal operation from 0V to V+ (e.g., 0V to +5V) in single-supply mode. The input voltage range for COM_, NO_, and NC_ terminals is specified as 0V to V+ under single-supply conditions. This enables full-scale signal switching without clipping in 5V microcontroller-based systems, provided V− is tied to GND and VL is set ≥2.7V (e.g., VL = V+ = +5V).
Is the 0.1nA off-leakage current for MAX4679EPE+ tested or guaranteed over temperature?
The 0.1nA off-leakage current for MAX4679EPE+ is guaranteed at +25°C and 100% tested at the maximum-rated hot operating temperature (+85°C) and highest supply voltage (+5.5V), then correlated to +25°C per Note 5 in the datasheet. Over the full −40°C to +85°C range, off-leakage is guaranteed to remain ≤10nA - verified by production testing, not extrapolation. This makes MAX4679EPE+ suitable for high-impedance sensor nodes where leakage-induced offset must be minimized.
