Product details
Overview
MAX4615CSD+ from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) CMOS analog switch optimized for low-voltage, high-speed signal routing. It operates from +2V to +5.5V, delivers 10Ω max on-resistance at +5V, matches channels within 1Ω max, and achieves 12ns turn-on/10ns turn-off times. It supports rail-to-rail analog signals and is used in battery-powered audio routing and low-voltage data acquisition.
For engineers reviewing the MAX4615CSD+ datasheet, MAX4615CSD+ pinout, MAX4615CSD+ application, or MAX4615CSD+ equivalent, key selection criteria include guaranteed on-resistance flatness (1Ω max), sub-6nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and pin compatibility with 74HC4066/MAX4610.
Technical Context
The MAX4615CSD+ implements four independent NC analog switches using complementary MOSFET pairs per channel, enabling bidirectional signal flow with rail-to-rail voltage handling (GND to V+). Its control logic interprets INx = LOW as ON (closed) and INx = HIGH as OFF (open), differing from the MAX4614's NO behavior.
Switch performance is specified across supply voltages: on-resistance is 10Ω max at +5V, 20Ω max at +3V, and 60Ω max at +2.5V; off-leakage remains ≤6nA at TA = +85°C; and dynamic parameters (tON/tOFF, charge injection, bandwidth) are characterized at multiple V+ and signal conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - Enables direct integration into 3.3V and 5V systems without level shifting. |
| On-Resistance (max) | 10Ω at +5V - Ensures minimal signal attenuation and distortion in precision analog paths. |
| On-Resistance Match | 1Ω max between channels - Critical for matched gain/attenuation in multi-channel instrumentation. |
| Turn-On / Turn-Off Time | 12ns / 10ns - Supports high-speed multiplexing in sampling and communication circuits. |
| Off-Leakage Current | 6nA at +85°C - Preserves accuracy in high-impedance sample-and-hold and sensor interfaces. |
| Analog Signal Range | GND to V+ - Allows full-rail signal switching without clipping in single-supply systems. |
| Logic Thresholds | VIN_H = 2.4V, VIN_L = 0.8V at +5V - Guarantees reliable TTL/CMOS interfacing without external translators. |
Pinout & Package
MAX4615CSD+ is housed in a 14-pin narrow SO (SOIC-N) package, 3.9mm wide, with standard 1.27mm pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 10 | NC1–NC4 | Normally closed analog terminals - Conduct when INx = LOW; bidirectional signal path. |
| 2, 4, 9, 11 | COM1–COM4 | Common analog terminals - Connect to signal source/load; shared node for each SPST switch. |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - Active-LOW enables closure (NC function); compatible with 5V TTL/CMOS. |
| 7 | GND | Ground reference - Return path for logic and analog sections; must be low-impedance. |
| 14 | V+ | Positive supply - Powers analog and digital circuitry; absolute max = +6V; decoupling required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from GND to V+ without degradation - eliminates need for dual supplies in portable designs. |
| Guaranteed on-resistance flatness | 1Ω max variation over full signal range - maintains consistent gain/attenuation across input amplitude. |
| Pin compatibility with 74HC4066/MAX4610 | Direct drop-in replacement in existing layouts - reduces redesign time and qualification effort. |
| Low charge injection (6.5pC) | Minimizes voltage glitch during switching - critical for precision sample-and-hold and ADC front-ends. |
| Sub-10nA off-leakage at +85°C | Preserves DC accuracy in high-Z sensor nodes and battery-monitoring circuits over temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610CSD+ | Same pinout and NC functionality; higher on-resistance (15Ω max at +5V vs. 10Ω) and slower tOFF (15ns vs. 10ns). | Suitable for less demanding speed/accuracy requirements; not recommended for >100ksps sampling. | Select MAX4615CSD+ when lower RON, tighter matching, or faster switching is required. |
| ADG1412BRUZ | Quad SPST NC switch with 1.8Ω max RON at +5V but requires ≥±5V dual supply or +15V single supply; not 2V–5.5V compatible. | Targeted at industrial/high-voltage systems; incompatible with battery-powered 3.3V logic domains. | Choose MAX4615CSD+ for single-supply, low-voltage portability; ADG1412BRUZ only where ultra-low RON justifies supply complexity. |
Compared with MAX4610CSD+, MAX4615CSD+ offers tighter on-resistance matching and faster switching; versus ADG1412BRUZ, it trades ultra-low RON for true single-supply 2V–5.5V operation and direct TTL/CMOS logic interface - making it optimal for space-constrained, battery-operated systems.

FAQ
What is the maximum supply voltage rating for MAX4615CSD+?
The absolute maximum supply voltage (V+) for MAX4615CSD+ is +6V. Operation above this level risks permanent damage. The device is fully specified from +2V to +5.5V, with on-resistance and leakage performance guaranteed across that range. Exceeding +6V violates Absolute Maximum Ratings and may compromise reliability even if functional temporarily.
Does MAX4615CSD+ support rail-to-rail analog signal switching?
Yes, MAX4615CSD+ supports rail-to-rail analog signal switching - its analog terminals (COMx, NCx) handle signals from GND to V+ without clipping or distortion. This is achieved via complementary CMOS topology and is explicitly guaranteed in the datasheet under "Analog Signal Range" (0V to V+). No external biasing or level-shifting is needed for full-swing signals.
How does the logic control work for the normally closed switches in MAX4615CSD+?
In MAX4615CSD+, each NC switch closes (conducts) when its corresponding INx input is driven LOW (≤0.8V), and opens (blocks) when INx is HIGH (≥2.4V). This active-LOW control is inherent to the NC configuration and differs from the MAX4614's NO behavior. All four INx inputs are TTL/CMOS-compatible at +5V, eliminating need for logic translators.
What is the guaranteed on-resistance matching between channels for MAX4615CSD+?
MAX4615CSD+ guarantees on-resistance matching of ≤1Ω maximum between any two channels at +5V supply and TA = TMIN to TMAX. This ∆RON = RON(max) − RON(min) specification ensures consistent gain, attenuation, or signal loss across all four switches - essential for multi-channel instrumentation, balanced signal routing, and ratio-metric measurements.
Is MAX4615CSD+ pin-compatible with industry-standard analog switches?
Yes, MAX4615CSD+ is pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches in the same 14-pin SO package. Pin assignments for V+, GND, INx, COMx, and NCx match exactly, enabling drop-in replacement without PCB modification. Functional equivalence includes NC topology, logic thresholds, and basic switching characteristics - though MAX4615CSD+ improves on RON, matching, and leakage.
