Product details
Overview
MAX4620CPD from Maxim Integrated is a low-voltage, quad single-pole/single-throw (SPST) analog switch with four normally open (NO) channels, ±15kV ESD protection on NO/NC pins, 70Ω max on-resistance at +5V, 0.5nA off-leakage at +25°C, and rail-to-rail signal handling - used in battery-powered audio routing and automated test equipment where mechanical relay replacement is required.
For engineers reviewing the MAX4620CPD datasheet, MAX4620CPD pinout, MAX4620CPD application, or MAX4620CPD equivalent, key selection criteria include guaranteed on-resistance flatness (2Ω typ), TTL/CMOS-compatible control inputs, +2V to +12V single-supply operation, and ESD robustness per IEC 1000-4-2 air-gap and contact discharge standards.
Technical Context
The MAX4620CPD implements CMOS-based SPST switches with integrated bidirectional SCRs on NO/NC terminals for ±15kV ESD protection, enabling latch-free operation without external clamping. Each channel operates bilaterally with rail-to-rail analog signal range and independent TTL/CMOS-level digital control.
Its architecture guarantees on-resistance matching (0.5Ω typ at +5V) and flatness (2Ω typ), supporting low-distortion signal routing. The device features no break-before-make timing (as it contains only NO switches), and maintains <0.015% THD across 20Hz–20kHz with 600Ω load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 70Ω at +5V supply - ensures minimal voltage drop and power loss in signal paths up to ±5V. |
| Off-Leakage Current | 0.5nA at TA = +25°C - preserves signal integrity in high-impedance sample-and-hold or sensor interfaces. |
| ESD Protection | ±15kV HBM, ±15kV IEC 1000-4-2 air-gap, ±8kV contact discharge - eliminates need for external TVS on NO/NC pins. |
| Supply Voltage Range | +2V to +12V single supply - supports direct integration into 3.3V, 5V, and 9V battery-powered systems. |
| Bandwidth (-3dB) | >300MHz - enables high-fidelity routing of video, RF sampling, and fast digital signals. |
| Total Harmonic Distortion | 0.015% at 20Hz–20kHz - meets fidelity requirements for professional audio switching applications. |
| Turn-On/Off Time | 90ns/50ns typical at +5V - supports multiplexing in data-acquisition systems with >10 MSPS throughput. |
Pinout & Package
MAX4620CPD is housed in a 14-pin plastic DIP package (0.300" wide), compatible with through-hole assembly and legacy prototyping environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog switch terminals - connect to signal sources only when corresponding INx is HIGH. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog ports - serve as bidirectional signal path junctions between NO and system loads. |
| 5–6, 12–13 | IN2–IN4, IN1 | TTL/CMOS-compatible digital control inputs - drive respective NO switches ON (HIGH) or OFF (LOW). |
| 7 | GND | Analog/digital ground reference - must be low-impedance return for both logic and analog paths. |
| 14 | V+ | Positive supply input - powers internal CMOS switch array and ESD protection circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| ESD-protected NO pins | ±15kV per IEC 1000-4-2 air-gap - prevents field failure in handheld test gear and unshielded audio interfaces. |
| On-resistance matching | 0.5Ω typical between channels at +5V - enables precise gain-matching in multi-channel instrumentation front-ends. |
| Rail-to-rail signal handling | Supports analog signals from GND to V+ - eliminates clipping in DC-coupled audio and sensor signal chains. |
| Low distortion | 0.015% THD at 20Hz–20kHz - maintains fidelity in studio-grade audio routing and measurement systems. |
| Single-supply operation | +2V to +12V range - simplifies power design in portable devices using Li-ion, alkaline, or regulated supplies. |
Applications
| Battery-Powered Audio Routing | Automated Test Equipment (ATE) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4610EPA | Quad SPST NO switch, same pinout, but rated for ±12kV HBM only and 100Ω max RON at +5V. | Lacks full IEC 1000-4-2 compliance; unsuitable for CE-marked portable equipment requiring Level 4 ESD immunity. | Select MAX4610EPA only for cost-sensitive, non-certified industrial control panels with lower ESD exposure risk. |
| ADG1412BRUZ | Quad SPST NO switch with 1.8Ω max RON at +5V, but requires dual ±15V supplies or +3.3V/+15V split supply; no integrated ESD protection. | Demands external ±15V rails and discrete TVS diodes - increases BOM count and board area vs. MAX4620CPD's single-supply + ESD-on-chip solution. | Choose ADG1412BRUZ only when ultra-low on-resistance (<2Ω) is mandatory and dual-supply infrastructure already exists. |
Compared with MAX4610EPA and ADG1412BRUZ, the MAX4620CPD uniquely combines single-supply operation (+2V to +12V), integrated ±15kV IEC-compliant ESD protection, and 70Ω max on-resistance - making it optimal for compact, battery-powered, and safety-certified designs where layout space and supply complexity are constrained.

FAQ
What is the maximum supply voltage rating for MAX4620CPD?
The MAX4620CPD has an absolute maximum supply voltage (V+ to GND) of +13V, with guaranteed functional operation from +2V to +12V. Operation near the upper limit requires a minimum 0.1µF bypass capacitor placed close to the V+ and GND pins to suppress supply transients induced by ESD events or switching noise.
Does MAX4620CPD support rail-to-rail analog signal switching?
Yes, the MAX4620CPD supports rail-to-rail analog signal switching - its analog terminals (NO and COM) handle input voltages from GND to V+ without clipping or distortion. This capability is confirmed in the datasheet's "Input Voltage Range" specification and verified across the full operating temperature range (-40°C to +85°C).
What is the on-resistance matching specification for MAX4620CPD?
The MAX4620CPD guarantees on-resistance matching of 0.5Ω typical (and 3Ω maximum) between its four NO switches at +5V supply and +25°C. This parameter is measured as ∆RON = RON(MAX) − RON(MIN) under specified conditions (V+ = 4.5V, ICOM = 1mA, VNO/VNC = 3.5V), ensuring consistent gain and attenuation across channels.
Can MAX4620CPD replace the 74HC4066 in existing designs?
Yes, the MAX4620CPD is explicitly designed as a pin-compatible replacement for the 74HC4066, sharing identical 14-pin DIP pinout and TTL/CMOS-compatible logic inputs. It improves upon the 74HC4066 with ±15kV ESD protection, lower on-resistance (70Ω vs. ~100Ω), and guaranteed rail-to-rail operation - requiring no PCB changes when upgrading.
What is the off-isolation performance of MAX4620CPD at 10MHz?
The MAX4620CPD provides -45dB off-isolation at 10MHz (RL = 50Ω, CL = 5pF), meaning a signal applied to an off-channel's NO terminal couples less than 6% in amplitude to the corresponding COM terminal. This value is measured per Figure 2 in the datasheet and ensures effective channel separation in RF and high-speed data routing.
