Product details
Overview
MAX4616CUD+ from Analog Devices is a quad SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, operating from +2V to +5.5V supply. It delivers 10Ω max on-resistance at +5V, 12ns turn-on time, rail-to-rail signal handling (0V to V+), and <6nA off-leakage at +85°C - enabling precision signal routing in low-voltage portable instrumentation.
For engineers reviewing the MAX4616CUD+ datasheet, MAX4616CUD+ pinout, MAX4616CUD+ application, or MAX4616CUD+ equivalent, key selection criteria include channel configuration (2NO/2NC), guaranteed RON matching (≤1Ω), flatness over signal range, TTL/CMOS logic compatibility, and TSSOP-14 package suitability for space-constrained PCB layouts.
Technical Context
The MAX4616CUD+ integrates four independent SPST switches in a single monolithic CMOS die, with dedicated NO and NC terminals per channel. Its architecture ensures matched on-resistance (≤1Ω max between channels) and flat on-resistance (≤1Ω variation across 0V to V+ signal range) - critical for multi-channel signal integrity in data-acquisition front-ends.
Logic inputs accept TTL/CMOS thresholds (+0.8V low, +2.4V high at +5V supply), enabling direct interface with microcontrollers without level-shifting. Switch control is fully static: IN1–IN4 directly enable/disable NO1/NO3 and NC2/NC4 per truth table, with no clock or serial interface required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports Li-ion battery (3.0–3.7V), USB-powered (5V), and low-power MCU I/O domains. |
| On-Resistance (RON) | 10Ω max at +5V - minimizes signal attenuation and gain error in precision analog paths. |
| RON Matching | ≤1Ω max between channels - enables accurate channel-to-channel signal ratio tracking in multiplexed systems. |
| Turn-On/Off Time | 12ns / 10ns at +5V - supports high-speed sampling and dynamic signal switching up to ~30MHz. |
| Off-Leakage Current | 6nA max at +85°C - preserves accuracy in high-impedance sensor interfaces and sample-and-hold hold phases. |
| Analog Signal Range | Rail-to-rail (0V to V+) - allows full-scale signal passage without clipping in single-supply systems. |
| Logic Compatibility | TTL/CMOS thresholds (+0.8V / +2.4V at +5V) - eliminates need for external level translators when driven by standard digital ICs. |
Pinout & Package
MAX4616CUD+ is housed in a 14-pin TSSOP package (3.0mm × 4.4mm, 0.65mm pitch), optimized for automated assembly and thermal performance in compact PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog terminals - connect only when corresponding IN1/IN3 = HIGH; bidirectional signal path. |
| 3, 11 | NC2, NC4 | Normally closed analog terminals - disconnect only when corresponding IN2/IN4 = HIGH; bidirectional signal path. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as shared signal entry/exit points for each SPST switch. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - drive NO/NC state per truth table; CMOS/TTL compatible thresholds. |
| 7 | GND | Analog/digital ground reference - must be low-impedance return path for signal and supply currents. |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| 2NO + 2NC channel configuration | Enables simultaneous signal pass-through and bypass routing - e.g., audio mute path (NC) + active path (NO) in same device. |
| Guaranteed RON flatness ≤1Ω | Maintains consistent gain and linearity across full analog input range - essential for 12-bit+ data acquisition accuracy. |
| Rail-to-rail signal handling | Supports 0V to full V+ analog swing without external biasing - simplifies design of single-supply sensor interfaces. |
| 14ns max tON, 12ns max tOFF | Meets timing requirements for 20MSPS sampling systems where switch settling must occur within <50ns. |
| 6nA max off-leakage at +85°C | Reduces voltage error in >1MΩ source impedance applications - critical for thermocouple and piezoelectric sensor conditioning. |
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 |
|---|---|---|---|
| MAX4614CUD+ | Four NO-only channels; identical RON, speed, and supply specs. | Suitable where all switches must be open-circuit by default (e.g., sensor disconnect on power-up). | Select when default-open behavior is required; not drop-in for 2NO/2NC logic states. |
| ADG1419BRUZ | Single 4-channel SPDT (not SPST); 1.5Ω RON at +5V; 16-pin TSSOP. | Provides true break-before-make switching; higher integration but larger footprint and different pinout. | Choose for SPDT functionality or lower RON; requires PCB redesign due to pin count and topology mismatch. |
Compared with MAX4614CUD+, MAX4616CUD+ adds NC functionality for fail-safe or default-path designs, while ADG1419BRUZ offers SPDT topology at lower RON but demands layout revision and logic re-mapping.

FAQ
What is the maximum supply voltage rating for MAX4616CUD+?
The absolute maximum supply voltage for MAX4616CUD+ is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. At +5.5V, RON remains ≤10Ω and off-leakage stays ≤6nA at +85°C - ensuring reliable operation within spec across its full temperature range. Always observe proper power-supply sequencing (apply V+ before analog/logic signals) to prevent latch-up.
How does the 2NO/2NC configuration of MAX4616CUD+ differ from MAX4614CUD+ in practical use?
MAX4616CUD+ integrates two normally open (NO) and two normally closed (NC) switches, enabling simultaneous default-path and controlled-path routing - e.g., NC2 maintains signal continuity until IN2 goes HIGH to break the path. In contrast, MAX4614CUD+ provides four NO switches only, requiring external pull-downs or logic inversion to emulate NC behavior. This makes MAX4616CUD+ ideal for safety-critical or power-loss default states without added components.
Can MAX4616CUD+ operate reliably at +2.5V supply?
Yes, MAX4616CUD+ is fully specified down to +2.5V: RON is 100Ω max, tON/tOFF are 6.5ns/2.8ns typical, and analog signal range remains rail-to-rail (0V to +2.5V). Off-leakage stays ≤10nA at +85°C. This enables direct integration with 2.5V FPGA I/O banks or ultra-low-power microcontrollers - confirmed by Electrical Characteristics tables for +2.5V supply in the official datasheet.
What is the significance of ≤1Ω RON matching between channels in MAX4616CUD+?
The ≤1Ω RON matching specification ensures that the resistance difference between any two switched channels remains under 1Ω across temperature and signal voltage - critical for applications like multi-channel current sensing or ratiometric bridge measurements where relative gain error must stay below 0.1%. This matching is guaranteed by design and tested across the full operating range, not just at +25°C.
Does MAX4616CUD+ require external protection diodes for overvoltage tolerance?
No, MAX4616CUD+ includes internal ESD protection diodes rated for ±2kV HBM, but external diodes (D1/D2 per Figure 1 in datasheet) are recommended only if analog inputs may exceed V+ by >0.3V or fall below GND by >0.3V - such as in hot-plug or fault conditions. Adding them reduces signal range by ~0.7V but keeps leakage unchanged; MAX4616CUD+ itself tolerates -0.3V to (V+ + 0.03V) on NO/NC/COM pins per Absolute Maximum Ratings.
