Product details
Overview
MAX4614CSD from Analog Devices is a quad, low-voltage, high-speed SPST analog switch with four normally open (NO) channels, 10Ω max on-resistance at +5V, 12ns turn-on time, and rail-to-rail signal handling from V+ to GND-used in battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4614CSD datasheet, MAX4614CSD pinout, MAX4614CSD application, or MAX4614CSD equivalent, this device delivers precise channel matching (≤1Ω), sub-6nA off-leakage at +85°C, TTL/CMOS-compatible logic thresholds, and SOIC narrow-package compatibility for space-constrained mixed-signal PCBs.
Technical Context
The MAX4614CSD implements CMOS transmission-gate architecture with matched P/N-channel pairs per switch, enabling flat on-resistance (<1Ω variation) across its 0V to V+ analog range. Its digital control inputs feature fixed 0.8V/2.4V thresholds-guaranteed for TTL/CMOS interoperability at +5V supply without level shifting.
Each NO switch operates bidirectionally with rail-to-rail analog capability, supported by <1nA COM_ on-leakage at +25°C and 11pF COM_ on-capacitance. The device sustains stable switching performance from +2V to +5.5V supply, with dynamic parameters (tON/tOFF) fully characterized over temperature and voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +5.5V - supports direct integration into 3.3V and 5V systems without regulators |
| On-Resistance (max) | 10Ω at +5V - ensures minimal signal attenuation and gain error in precision signal paths |
| On-Resistance Match | ≤1Ω max between channels - enables accurate differential or multi-channel ratio-metric measurements |
| Turn-On / Turn-Off Time | 12ns / 10ns at +25°C - suitable for high-speed multiplexing up to ~70MHz bandwidth |
| Off-Leakage Current | 6nA max at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor interfaces |
| Analog Signal Range | 0V to V+ - allows full-rail signal passage without clipping in single-supply systems |
| Logic Thresholds | VIN_L = 0.8V, VIN_H = 2.4V - guarantees reliable switching with standard 5V TTL/CMOS drivers |
Pinout & Package
MAX4614CSD is housed in a 14-pin narrow SO (SOIC-N) package, 3.9mm width, JEDEC MS-012 compliant, with 1.27mm pitch and gull-wing leads. Thermal derating is 8.00mW/°C above +70°C; max continuous power dissipation is 640mW at +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - connect only when corresponding INx is HIGH; bidirectional signal path |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for all four SPST switches |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive NOx closure when HIGH (logic 1) |
| 7 | GND | Ground reference - return path for logic and analog circuitry; must be low-impedance |
| 14 | V+ | Positive supply - powers analog switch core and input buffers; accepts +2V to +5.5V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog operation | Supports 0V to V+ signal swing - eliminates need for level-shifting in single-supply data acquisition |
| Guaranteed channel matching | ≤1Ω on-resistance mismatch - critical for instrumentation-grade multiplexing and chopper-stabilized designs |
| Ultra-low off-leakage | <6nA at +85°C - maintains integrity of high-Z sensor nodes and long-time-constant hold capacitors |
| Fast, predictable switching | 12ns tON/10ns tOFF with <2ns skew - enables synchronous sampling across multiple channels |
| Pin compatibility | Drop-in replacement for 74HC4066/MAX4610 - allows legacy design upgrades without layout change |

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 |
|---|---|---|---|
| MAX4615CSD | Four normally closed (NC) switches instead of NO; identical pinout, timing, and electrical specs | Used where default-closed signal paths are required (e.g., fail-safe sensor disconnect) | Select MAX4615CSD when default conduction is needed; otherwise MAX4614CSD provides default-open safety isolation |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typ at +5V), wider supply (±5V or +5V single), 16-TSSOP package | Targeted at higher-precision, dual-supply systems requiring lower RON flatness and enhanced ESD robustness | Choose ADG1414BRUZ for ±5V operation or sub-2Ω RON; MAX4614CSD remains optimal for cost-sensitive +2V–+5.5V battery designs |
Compared with MAX4615CSD, MAX4614CSD provides safe default-open behavior ideal for power-sensitive signal gating; versus ADG1414BRUZ, it offers narrower SOIC packaging and lower system BOM cost at the expense of dual-supply flexibility and ultra-low RON.

FAQ
What is the maximum supply voltage rating for MAX4614CSD?
The absolute maximum supply voltage for MAX4614CSD is +6V, but the recommended operating range is +2V to +5.5V. Exceeding +6V risks permanent damage due to internal diode clamping. Operation at +5.5V maintains full specification compliance for on-resistance, leakage, and switching speed - critical for robust deployment in 5V industrial and consumer systems using MAX4614CSD.
Does MAX4614CSD support rail-to-rail analog signal operation?
Yes, MAX4614CSD supports true rail-to-rail analog signal handling from 0V to V+, meaning signals can swing across the full supply range without clipping or distortion. This is enabled by its CMOS transmission-gate architecture and verified across all operating temperatures and supply voltages - making MAX4614CSD suitable for single-supply data acquisition, audio, and sensor interface applications where headroom is constrained.
What is the guaranteed on-resistance match between channels in MAX4614CSD?
MAX4614CSD guarantees ≤1Ω maximum on-resistance mismatch between any two channels at +25°C, and ≤1.2Ω over the full 0°C to +70°C operating range. This tight matching is measured under standardized conditions (V+ = 4.5V, ICOM = 10mA) and directly supports precision applications like ratiometric sensing and multi-channel calibration - a key differentiator of MAX4614CSD versus generic analog switches.
Can MAX4614CSD be used with a +3.3V supply?
Yes, MAX4614CSD is fully specified and characterized for +3.3V operation: on-resistance is 20Ω max, tON/tOFF are 15ns/12ns max, and logic thresholds remain compatible (VIN_H = 2.0V, VIN_L = 0.8V). Its +2V to +5.5V supply range makes MAX4614CSD ideal for mixed-voltage systems - especially where +3.3V microcontrollers control analog signal paths without level translators.
Is MAX4614CSD pin-compatible with industry-standard analog switches?
Yes, MAX4614CSD is pin-compatible with the 74HC4066 and MAX4610 - sharing identical 14-pin narrow SO footprint, pin assignments, and functional mapping. This allows drop-in replacement in existing designs, reducing redesign effort and qualification time. All four NO switches, COM terminals, control inputs, V+, and GND align exactly - confirmed in the MAX4614CSD pin configuration diagram and ordering table.
