Product details
Overview
The MAX4622CSE+T from Maxim Integrated is a dual, single-pole/double-throw (SPDT) analog switch with two normally closed (NC) and two normally open (NO) poles, 5Ω maximum on-resistance, guaranteed 0.5Ω max RON match between channels, and break-before-make operation - ideal for precision signal routing in test equipment and communication systems.
For engineers reviewing the MAX4622CSE+T datasheet, MAX4622CSE+T pinout, MAX4622CSE+T application, or MAX4622CSE+T equivalent, key selection criteria include rail-to-rail analog signal handling (±18V bipolar / +36V single supply), <200ns turn-off time, <250ns turn-on time, <5nA off-leakage at +85°C, and SOIC-16 package compatibility with DG403.
Technical Context
The MAX4622CSE+T implements CMOS-based SPDT switching with guaranteed break-before-make timing to prevent signal shorting during state transitions. Its dual-channel architecture supports independent control of two SPDT switches via separate logic inputs (IN1, IN2), each driving one COM/NO/NC set.
It operates across wide supply ranges: ±4.5V to ±18V bipolar or +4.5V to +36V single supply, with TTL/CMOS-compatible logic inputs (VIL = 0.8V, VIH = 2.4V) and rail-to-rail analog voltage handling from V− to V+ - enabling seamless integration into mixed-signal systems without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 5Ω max - ensures minimal signal attenuation and distortion in low-impedance audio/data paths |
| RON match | 0.5Ω max between channels - critical for matched gain/phase in differential or dual-path circuits |
| Turn-off time | <200ns - enables high-speed multiplexing in automated test equipment (ATE) and data acquisition |
| Off-leakage current | <5nA at +85°C - preserves signal integrity in high-impedance sensor interfaces and precision measurement |
| Analog signal range | V− to V+ - supports rail-to-rail input/output swing without clipping in ±15V or +12V systems |
| Logic compatibility | TTL/CMOS - allows direct interfacing with microcontrollers, FPGAs, and logic families without buffers |
| Supply range | ±4.5V to ±18V or +4.5V to +36V - accommodates industrial, avionics, and telecom power architectures |
Pinout & Package
MAX4622CSE+T is housed in a 16-pin narrow SOIC (SO/DIP) package with 1.27mm pitch, 10.3mm × 5.3mm body size, and surface-mount footprint compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | Digital logic input (IN1, IN2) | Active-high control for respective SPDT switch; drives internal CMOS gate |
| 2, 7 | Switch common terminal (COM1, COM2) | Center pole connection - routed to NO or NC based on logic state |
| 3, 6, 9, 16 | Normally open terminal (NO1, NO2, NO3, NO4) | Open-circuit when logic = 0; connects to COM only when logic = 1 |
| 4, 5, 10, 15 | Normally closed terminal (NC1, NC2, NC3, NC4) | Closed-circuit when logic = 0; disconnects from COM when logic = 1 |
| 12 | Positive supply (V+) | Primary analog supply rail - sets upper analog voltage limit |
| 1, 3, 6, 8 | Negative supply (V−) | Analog negative rail - sets lower analog voltage limit in bipolar operation |
| 14 | Ground (GND) | Reference for logic inputs and internal biasing; must be tied to system ground |
| 13 | Logic supply (VL) | Separate 5V rail for logic interface - isolates digital noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Prevents momentary shorting between NC and NO paths during switching - essential for fault-tolerant signal routing |
| Rail-to-rail analog handling | Supports full V− to V+ signal swing without distortion - eliminates need for external clamping or level shifters |
| Low on-resistance flatness | ΔRON ≤ 0.5Ω over full signal range - maintains consistent gain/attenuation across input voltage |
| Ultra-low leakage at temperature | <5nA at +85°C - ensures stable DC accuracy in high-impedance medical or sensor front-ends |
| Pin compatibility with DG403 | Direct drop-in replacement for legacy DG403 - reduces redesign effort and qualification time |
Applications
| Test Equipment Signal Routing | Avionics Data Multiplexing |
|---|---|
Use Scenario: Automated test equipment (ATE) uses dynamic channel selection to route calibration signals between DUT and instrumentation. IC Role / Device Role / Timing Role: Dual SPDT switch routes reference voltages and sensor outputs under microcontroller control with sub-250ns switching. Use Value: Break-before-make prevents transient shorts during reconfiguration; 5Ω RON minimizes loading on precision DACs and ADCs. | Use Scenario: Flight control systems multiplex analog sensor data (e.g., gyros, accelerometers) across shared telemetry buses. IC Role / Device Role / Timing Role: MAX4622CSE+T acts as a fault-isolated analog mux, selecting among redundant sensor inputs before conditioning. Use Value: Rail-to-rail support handles ±10V sensor outputs directly; <5nA leakage ensures long-term DC stability in unattended operation. |
| Communications PBX Switching | Audio Signal Path Selection |
Use Scenario: Private branch exchange (PBX) systems route voice signals between lines, trunks, and conferencing resources. IC Role / Device Role / Timing Role: SPDT configuration selects between primary and backup voice paths with simultaneous NC/NO control per channel.

IC Role / Device Role / Timing Role: Dual SPDT provides independent left/right channel routing with break-before-make to avoid pops/clicks. Use Value: Low 5Ω RON and flatness preserve frequency response; <200ns tOFF enables glitch-free mute/unmute transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4622ESE+ | Extended temperature range (−40°C to +85°C) vs. MAX4622CSE+T (0°C to +70°C); identical electrical specs and pinout | Suitable for automotive or outdoor industrial deployments requiring wider thermal margin | Select MAX4622ESE+ when operating ambient exceeds +70°C or requires MIL-STD-810 qualification |
| ADG408BRUZ | 8-channel single-pole/single-throw (SPST) vs. dual SPDT; 45Ω typical RON, no break-before-make guarantee | Better for high-channel-count, low-speed multiplexing; unsuitable for NC/NO dual-path or short-circuit–sensitive use cases | Choose ADG408BRUZ only when channel count outweighs speed, leakage, and switching safety requirements |
Compared with MAX4622ESE+, the MAX4622CSE+T offers identical performance at lower cost for commercial-temperature applications; compared with ADG408BRUZ, it delivers superior speed, lower RON, and guaranteed break-before-make - making it preferred for precision dual-path routing where signal integrity and switching safety are critical.

FAQ
What is the maximum supply voltage rating for MAX4622CSE+T in single-supply operation?
The MAX4622CSE+T supports a single positive supply from +4.5V to +36V. Absolute maximum rating is +44V referenced to GND. Operation above +36V is not guaranteed and may cause permanent damage. For reliable long-term use, stay within the specified +4.5V to +36V range, with derating applied above +70°C ambient.
Does MAX4622CSE+T require separate logic and analog supplies?
Yes - MAX4622CSE+T has dedicated VL (pin 13) for logic interface and V+ (pin 12)/V− (pins 1,3,6,8) for analog signal path. VL must be 5V (±10%), while V+/V− define the analog rail limits. This separation prevents digital noise coupling into sensitive analog nodes and ensures clean switching behavior.
Is MAX4622CSE+T pin-compatible with the DG403 analog switch?
Yes - MAX4622CSE+T is explicitly designed as a pin-compatible replacement for the DG403, sharing identical SOIC-16 pinout, terminal functions, and logic polarity. No PCB layout changes are required; however, verify that system-level timing and leakage budgets align with MAX4622CSE+T's improved specs (e.g., lower RON, faster switching).
What does "break-before-make" mean for MAX4622CSE+T, and how is it guaranteed?
Break-before-make ensures that the NC path opens completely before the NO path closes during logic transitions - eliminating momentary short circuits between NC and NO terminals. MAX4622CSE+T guarantees this behavior across all temperature and supply conditions per its datasheet truth table and timing specifications (tD ≥ 90ns min), verified by production testing.
Can MAX4622CSE+T handle bipolar analog signals up to ±15V?
Yes - MAX4622CSE+T supports bipolar supplies from ±4.5V to ±18V, enabling full ±15V analog signal handling (V− = −15V, V+ = +15V). The device maintains 5Ω max RON, <200ns tOFF, and <5nA leakage at +85°C under these conditions, as confirmed in the dual-supply electrical characteristics table.
