Product details
Overview
MAX4614CPD 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-designed for precision signal routing in battery-powered audio/video systems.
For engineers reviewing the MAX4614CPD datasheet, MAX4614CPD pinout, MAX4614CPD application, or MAX4614CPD equivalent, this device is selected for low-leakage (<1nA @ +25°C), matched channel resistance (≤1Ω), and TTL/CMOS logic compatibility across +2V to +5.5V supply operation.
Technical Context
The MAX4614CPD implements CMOS transmission-gate architecture with independent digital control inputs (IN1–IN4) enabling individual channel switching. Each NO switch connects COMx to NOx when its input is HIGH, supporting bidirectional analog signals up to V+.
It guarantees flat on-resistance (≤1Ω variation over full signal range) and tight matching (≤1Ω max difference between any two channels), critical for multiplexer accuracy and sample-and-hold fidelity. Off-isolation exceeds -85dB at 100kHz, minimizing crosstalk in multi-channel routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 10Ω max at +5V supply - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| On-Resistance Match | 1Ω max between channels - enables precise gain/offset matching in differential or multi-path circuits |
| Turn-On/Off Time | 12ns tON / 10ns tOFF - supports high-speed multiplexing in data acquisition and communication interfaces |
| Off-Leakage Current | 1nA max at +25°C - preserves signal integrity in high-impedance sensor and sample-hold nodes |
| Analog Signal Range | 0V to V+ - allows rail-to-rail signal handling without clipping in single-supply systems |
| Logic Thresholds | +0.8V low / +2.4V high - ensures reliable TTL/CMOS compatibility with +5V supply |
| Supply Voltage Range | +2V to +5.5V - supports operation from Li-ion battery down to regulated 2.5V rails |
Pinout & Package
MAX4614CPD uses a 14-pin plastic DIP package (0.300" wide), through-hole mountable, with 100% lead (Pb)-free finish per JEDEC J-STD-609.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - connect to COMx only when corresponding INx is HIGH |
| 2, 4, 9, 10 | COM1–COM4 | Common bidirectional analog ports - serve as signal input/output shared with NO/NC paths |
| 5, 6, 12, 13 | IN1–IN4 | Digital control inputs - TTL/CMOS-compatible; drive internal switches directly |
| 7 | GND | Ground reference for logic and analog sections - must be low-impedance for leakage and noise control |
| 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 distortion or clipping - essential for single-supply instrumentation |
| Guaranteed on-resistance flatness | ≤1Ω variation across full 0V–V+ signal range - maintains consistent gain in variable-amplitude paths |
| Channel-to-channel on-resistance match | ≤1Ω max mismatch - enables accurate ratio-metric measurements in multi-channel ADC front-ends |
| Low charge injection (6.5pC) | Minimizes voltage glitch on sampled nodes - improves accuracy in sample-and-hold and switched-capacitor circuits |
| High off-isolation (-85dB) | Reduces signal coupling between inactive channels - critical for high-fidelity audio and RF-adjacent routing |

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 |
|---|---|---|---|
| MAX4614CSD | Same electrical specs, but in 14-pin narrow SOIC package - surface-mount, 5.3mm × 4.4mm footprint | Preferred for automated PCB assembly and space-constrained designs; requires reflow not wave soldering | Select MAX4614CSD when board real estate or manufacturing process favors SMT over through-hole. |
| ADG1414BRUZ | 4-channel SPST, 1.5Ω typical RON, ±15V dual-supply capable; higher cost, larger 16-TSSOP package | Suitable for bipolar signal routing (±5V, ±12V) and higher-precision instrumentation where sub-2Ω matching is required | Choose ADG1414BRUZ only if dual-supply operation or <2Ω RON is mandatory - not a drop-in replacement. |
Compared with MAX4614CPD, MAX4614CSD offers identical performance in a smaller SMT package ideal for volume production, while ADG1414BRUZ extends voltage range and reduces on-resistance at the cost of pin count, footprint, and supply flexibility.

FAQ
What is the maximum supply voltage rating for MAX4614CPD?
The absolute maximum supply voltage (V+) for MAX4614CPD is +6V. Operation above +5.5V is not recommended, as the device is specified for reliable performance from +2V to +5.5V. Exceeding +6V risks permanent damage per the Absolute Maximum Ratings table in the datasheet. The MAX4614CPD must never be operated beyond this limit, even transiently.
Does MAX4614CPD support bidirectional analog signal flow?
Yes, MAX4614CPD supports fully bidirectional analog signal flow on all COM–NO paths. Each switch functions as a symmetrical transmission gate: signal direction (COM→NO or NO→COM) is determined by external circuit topology, not device polarity. This enables flexible use in both input and output signal routing applications without redesign.
What is the guaranteed on-resistance flatness specification for MAX4614CPD at +5V?
At +5V supply, MAX4614CPD guarantees on-resistance flatness of ≤1Ω maximum - defined as the difference between highest and lowest RON measured across the full 0V to +5V analog signal range. This specification holds over the full operating temperature range (0°C to +70°C) and ensures consistent gain and linearity in variable-amplitude signal paths.
Can MAX4614CPD be used with a +3.3V supply, and what is its on-resistance under that condition?
Yes, MAX4614CPD operates reliably at +3.3V. At +3V supply and +25°C, its typical on-resistance is 8Ω with a maximum of 20Ω. Over the full temperature range (0°C to +70°C), RON is guaranteed ≤25Ω. This makes MAX4614CPD suitable for modern low-voltage systems while maintaining predictable analog path impedance.
Is MAX4614CPD pin-compatible with the 74HC4066?
Yes, MAX4614CPD is explicitly designed to be pin-compatible with the industry-standard 74HC4066 and MAX4610 analog switches. Its 14-pin DIP pinout matches those devices exactly - including identical assignments for COM1–COM4, NO1–NO4, IN1–IN4, V+, and GND - enabling direct replacement without PCB modification.
