Product details
Overview
MAX4538CSE+T from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, common enable pin, rail-to-rail signal handling, 200Ω max on-resistance at +4.5V single supply, and 100ns turn-on time at ±4.5V - used in audio-signal routing and low-voltage data acquisition systems.
For engineers reviewing the MAX4538CSE+T datasheet, MAX4538CSE+T pinout, MAX4538CSE+T application, or MAX4538CSE+T equivalent, this page delivers verified electrical specs, package mapping to 16-pin narrow SO, truth-table–validated switching behavior, and real-world leakage/flatness/on-capacitance values per operating condition.
Technical Context
The MAX4538CSE+T implements CMOS transmission-gate architecture with complementary N- and P-channel MOSFETs per switch, driven by logic-level translators that isolate digital control (V+/GND) from analog supplies (V+/V−). Its break-before-make timing (15ns typ) prevents signal shorting during channel transitions in mixed NO/NC configurations.
ESD protection (>2kV per Method 3015.7) is achieved via internal diodes between each analog pin and V+/V−, with leakage current routed exclusively to supply rails-not ground-enabling true floating analog paths. Logic thresholds (0.8V/2.4V at +5V) ensure TTL/CMOS compatibility across single (+2V to +12V) and dual (±2V to ±6V) supply modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply or ±2V to ±6V dual supply - supports battery-powered and bipolar-rail systems without level-shifting. |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal insertion loss in precision signal paths up to 10mA. |
| RON Flatness | 10Ω max over full signal range - maintains consistent gain/attenuation across rail-to-rail analog inputs (V− to V+). |
| Off-Leakage Current | 10nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits. |
| Switching Speed | tON = 100ns, tOFF = 80ns at ±4.5V - enables reliable multiplexing in 10MHz-class data acquisition and test equipment. |
| Charge Injection | 5pC max - minimizes voltage glitch on sampled nodes, critical for ADC front-end accuracy. |
| Off-Isolation | −65dB at 1MHz - suppresses crosstalk between active and inactive channels in dense routing applications. |
Pinout & Package
MAX4538CSE+T is housed in a 16-pin narrow SO package (JEDEC MS-012AA, 3.9mm × 9.9mm body, 1.27mm pitch), RoHS-compliant and tape-and-reel packaged for automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal | Bidirectional signal path node shared between NO/NC pairs; accepts rail-to-rail voltages from V− to V+. |
| 2, 3, 11, 12 (NO1–NO4 / NC1–NC4) | Analog switch terminal | MAX4538-specific: Pins 2 & 11 = NO; Pins 3 & 12 = NC - defines hardwired SPST topology per channel. |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input | Individually selects NO/NC state per switch when EN = low; logic thresholds fixed at 0.8V/2.4V. |
| 7 (EN) | Global enable | Active-low: logic high disables all four switches simultaneously - essential for power sequencing and fault isolation. |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog current return path - enables true floating analog operation. |
| 9 (V−) | Negative analog supply | Connect to GND for single-supply use; sets lower bound of analog signal range and P-MOSFET gate drive. |
| 16 (V+) | Positive analog/digital supply | Powers internal logic translators and switch gates; internally tied to substrate for ESD robustness. |
Key Features
| Feature | Design Value |
|---|---|
| Two NO + two NC configuration | Enables simultaneous signal pass-through and default-path routing (e.g., mute + bypass) without external logic. |
| Break-before-make timing | 15ns typical interval prevents momentary shorting between COM and NO/NC during transition - critical for audio and avionics safety. |
| Rail-to-rail analog signal range | V− to V+ operation supports full dynamic range of sensors, DACs, and op-amps without clamping or distortion. |
| TTL/CMOS-compatible inputs | 0.8V/2.4V thresholds at +5V supply eliminate need for external level shifters when interfacing with microcontrollers or FPGAs. |
| Low 1µW quiescent power | Reduces thermal load and extends battery life in portable equipment - supply currents <1µA at +25°C. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | Single-supply only (+5V to +16.5V); 4.7Ω RON; no NC/NO mix - all four channels are SPDT with break-before-make. | Requires redesign for dual-supply or mixed NO/NC topology; better for high-precision DC-coupled instrumentation. | Select ADG1419BRUZ when ultra-low on-resistance and guaranteed break-before-make are prioritized over supply flexibility. |
| TS5A3159DCKR | Single-supply only (1.65V to 5.5V); 0.75Ω RON; 30ns tON; no dual-supply support; smaller SC70-6 package. | Not suitable for ±5V avionics or rail-to-rail industrial sensors; limited to low-voltage consumer portables. | Choose TS5A3159DCKR for space-constrained, battery-powered USB audio docks where sub-1Ω RON justifies single-supply limitation. |
Compared with MAX4538CSE+T, ADG1419BRUZ offers lower on-resistance but lacks dual-supply operation and mixed NO/NC topology, while TS5A3159DCKR provides faster switching in a smaller footprint but cannot replace MAX4538CSE+T in bipolar-rail or high-isolation applications.

FAQ
What is the operating temperature range for MAX4538CSE+T?
The MAX4538CSE+T is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range is validated across all electrical parameters including on-resistance flatness, leakage current, and switching speed - ensuring reliability in portable equipment and benchtop test instruments where ambient conditions remain controlled.
Does MAX4538CSE+T support dual-supply operation?
Yes, MAX4538CSE+T operates from ±2V to ±6V dual supplies. The device uses separate V+ and V− pins to bias internal CMOS switches, enabling true bipolar analog signal handling from V− to V+. This mode is essential for applications like avionics signal conditioning where ±5V buses are standard and rail-to-rail dynamic range must be preserved.
How does the MAX4538CSE+T differ from MAX4536CSE+T and MAX4537CSE+T?
The MAX4538CSE+T integrates two normally open (NO) and two normally closed (NC) SPST switches in one package, whereas MAX4536CSE+T contains four NO switches and MAX4537CSE+T contains four NC switches. This hybrid configuration allows concurrent default-path and selectable-path routing - e.g., maintaining a backup signal path while switching primary inputs - without external logic.
What is the maximum allowable V+ to V− differential voltage for MAX4538CSE+T?
The absolute maximum V+ to V− differential voltage for MAX4538CSE+T is 13.0V. Exceeding this - even momentarily due to supply overshoot or noise - risks permanent damage. For example, ±6V supplies with ±10% tolerance reach 13.2V and must be derated; ±5V supplies are recommended for robust design margin in dual-supply systems.
Is MAX4538CSE+T pin-compatible with industry-standard logic devices?
Yes, MAX4538CSE+T is pin-compatible with the 74HC4316 quad analog switch. This allows drop-in replacement in existing layouts using the same 16-pin SO footprint, simplifying upgrades to lower on-resistance, improved leakage performance, and dual-supply capability without PCB revision.
