Product details
Overview
MAX353CSE+ from Maxim Integrated is a precision quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fabricated in a 44V silicon-gate process. It delivers <35Ω on-resistance (±2Ω matching), <10pC charge injection, <6nA off-leakage at +85°C, and rail-to-rail analog signal handling up to ±20V supplies - used in military radios and guidance systems where channel matching and low distortion are critical.
For engineers reviewing the MAX353CSE+ datasheet, MAX353CSE+ pinout, MAX353CSE+ application, or MAX353CSE+ equivalent, key selection criteria include guaranteed on-resistance flatness (∆3Ω max), break-before-make timing (25ns), dual- or single-supply operation (+10V to +30V or ±4.5V to ±20V), and ESD tolerance >2000V per Method 3015.7.
Technical Context
The MAX353CSE+ implements four independent SPST switches in a single monolithic IC, with dedicated NO/NC topology per channel pair (pins 1/4 = NO, pins 2/3 = NC). Its CMOS-compatible logic inputs (TTL/CMOS) interface directly to microcontrollers without level-shifting, while the VL pin allows flexible logic supply configuration (5V or V+).
Designed for high-precision signal routing, it guarantees matched on-resistance (<2Ω between channels) and flat on-resistance over full analog range (∆3Ω max), validated only under bipolar-supply operation. Charge injection is tightly controlled (<10pC) to minimize transient errors in sample-and-hold circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On Resistance | 35Ω max - ensures minimal signal attenuation and voltage drop across switched paths at full analog range. |
| On Resistance Match | ≤2Ω between channels - enables precise gain/offset matching in multi-channel instrumentation front-ends. |
| Charge Injection | 10pC max - limits settling error in sample-and-hold and ADC input conditioning stages. |
| Off-Leakage Current | 6nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-operated systems. |
| Switching Speed | tON < 175ns, tOFF < 145ns - supports multiplexing of medium-frequency analog signals up to ~2MHz. |
| Analog Signal Range | Rail-to-rail: V– to V+ - accommodates full-swing signals without clipping in ±15V or +12V systems. |
| ESD Rating | >2000V per Method 3015.7 - provides robust handling during board assembly and field maintenance. |
Pinout & Package
MAX353CSE+ uses a 16-pin narrow SOIC package (JEDEC MS-012AA, 3.9mm width), with exposed pad not electrically connected. Pin functions are defined per the MAX353-specific truth table and functional diagram in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 2, 15, 14) | Logic control inputs | CMOS/TTL-compatible digital inputs controlling individual switch states; IN1/IN4 control NO channels, IN2/IN3 control NC channels. |
| COM1–COM4 (Pins 3, 4, 13, 12) | Analog common terminals | Input/output nodes shared between NO and NC paths per channel; must be routed with controlled impedance for signal integrity. |
| NO1, NO4 (Pins 16, 5) | Normally open analog terminals | Open-circuit when IN = 0; connect to COMx only when corresponding INx = 1 - used for active-path routing. |
| NC2, NC3 (Pins 11, 9) | Normally closed analog terminals | Shorted to COMx when IN = 0; disconnect when INx = 1 - enables fail-safe or default-path configurations. |
| V+, V– (Pins 10, 4) | Analog supply rails | Support ±4.5V to ±20V or +10V to +30V operation; V+ tied to substrate - requires solid grounding for noise immunity. |
| VL (Pin 12) | Logic supply reference | Set to 5V for TTL compatibility or to V+ for CMOS logic thresholds; decoupling to GND essential for clean switching. |
| GND (Pin 3) | Digital ground reference | Return path for logic currents; must be star-connected to analog ground to avoid coupling noise into switched signals. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Operates with VCOM from V– to V+ - eliminates need for external level-shifting in ±15V industrial control I/O modules. |
| Guaranteed on-resistance flatness | ∆3Ω max over full analog range - maintains consistent gain in programmable-gain amplifier (PGA) feedback networks. |
| Break-before-make timing | 25ns (MAX353 only) - prevents momentary shorting between NO and NC paths during state transitions in safety-critical guidance systems. |
| Low power consumption | 35µW typical - extends battery life in portable test equipment and handheld military comms devices. |
| ESD-hardened architecture | >2000V HBM - reduces field failure risk in unshielded avionics and ruggedized PBX installations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | 4-channel SPST, 1.8Ω typical RON, but only NO configuration; no NC channels. | Suitable for pure multiplexing, not fail-safe or dual-path designs requiring NC functionality. | Select ADG1412BRUZ only if all four channels require normally open behavior and lower on-resistance is prioritized over NC capability. |
| TS5A3157DCKR | Single-channel SPST, 0.75Ω RON, 5V-only supply, no bipolar support. | Limited to low-voltage consumer electronics; cannot replace MAX353CSE+ in ±15V or rail-to-rail industrial systems. | Use TS5A3157DCKR only in cost-sensitive, single-channel, 5V-only applications where bipolar operation and NC function are unnecessary. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX353CSE+ uniquely combines dual NO/NC topology, ±20V bipolar operation, and guaranteed channel matching - making it irreplaceable in military and aerospace signal routing where functional redundancy and wide supply tolerance are mandatory.

FAQ
What is the maximum allowable supply voltage for MAX353CSE+?
The MAX353CSE+ supports absolute maximum ratings of V+ ≤ 44V relative to V–, with recommended dual-supply operation from ±4.5V to ±20V or single-supply operation from +10V to +30V. Exceeding these limits risks permanent damage, and operation above ±20V or +30V voids guaranteed specifications including on-resistance flatness and leakage performance.
Does MAX353CSE+ support break-before-make switching?
Yes, the MAX353CSE+ guarantees a 25ns break-before-make time delay (tD) between NO and NC paths within each channel pair - confirmed in the datasheet's Figure 3 test circuit and Electrical Characteristics table. This prevents momentary shorts during logic transitions, critical for safety-critical guidance system signal routing.
How does the VL pin function in MAX353CSE+?
The VL pin on MAX353CSE+ sets the logic threshold reference: tie to +5V for TTL compatibility (VINH ≥ 2.4V, VINL ≤ 0.8V) or to V+ for CMOS-level inputs. It must be decoupled with a 0.1µF capacitor to GND. Leaving VL floating or mismatched to logic driver levels causes undefined switching behavior and increased glitch risk.
What is the guaranteed on-resistance matching specification for MAX353CSE+?
The MAX353CSE+ guarantees on-resistance matching of ≤2Ω between any two channels under bipolar-supply conditions (e.g., ±15V), as specified in the Electrical Characteristics table. This matching is not guaranteed under single-supply operation, and deviation increases outside the –40°C to +85°C temperature range.
Can MAX353CSE+ operate with unbalanced supplies like +24V and –5V?
Yes, MAX353CSE+ supports unbalanced supplies such as +24V and –5V, provided the differential voltage (V+ – V–) does not exceed 44V and both rails remain within their absolute maximum ratings. The analog signal range adjusts accordingly - e.g., with +24V/–5V, VCOM may swing from –5V to +24V, requiring careful level alignment in downstream circuitry.
