Product details
Overview
MAX4538CEE+ from Maxim Integrated is a quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, common enable pin, ±2V to ±6V dual or +2V to +12V single supply operation, 200Ω max on-resistance, rail-to-rail signal handling, and 100ns turn-on time at ±4.5V - used in audio-signal routing and low-voltage data acquisition systems.
For engineers reviewing the MAX4538CEE+ datasheet, MAX4538CEE+ pinout, MAX4538CEE+ application, or MAX4538CEE+ equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-confirmed pin mapping for QSOP-16, and real-world leakage/flatness/timing data per operating condition (±5V, +5V, +3V).
Technical Context
The MAX4538CEE+ integrates four independent CMOS SPST switches with shared digital enable (EN), where IN1–IN4 control individual channel states while EN overrides all to OFF. Its internal logic-level translators isolate TTL/CMOS-compatible inputs (0.8V/2.4V thresholds at +5V) from analog supplies V+ and V−, enabling rail-to-rail signal switching without ground reference.
Each switch uses paralleled N- and P-channel MOSFETs driven out-of-phase by V+ and V−, delivering flat on-resistance (≤10Ω over signal range) and matched channel resistance (≤6Ω max mismatch). Break-before-make timing (15ns typ, 50ns max) is explicitly specified only for MAX4538 variants and validated under ±4.5V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rails without level-shifting. |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in precision analog paths. |
| RON Flatness | 15Ω max over full signal range - maintains consistent gain/attenuation across input voltage swing. |
| Channel Matching (∆RON) | 6Ω max - critical for differential or multi-path signal routing requiring amplitude consistency. |
| Turn-On/Off Time | 125ns/60ns max at ±4.5V - enables reliable switching in audio and test-equipment timing windows. |
| Off-Leakage Current | 10nA max at +85°C - preserves signal integrity in high-impedance sensor front-ends. |
| Charge Injection | 5pC max - limits voltage glitch on sampled-hold nodes and ADC inputs. |
Pinout & Package
MAX4538CEE+ is housed in a 16-pin QSOP package (5.0mm × 4.0mm, 0.635mm pitch), RoHS-compliant and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal | Bidirectional signal path node - connects to source or load depending on NO/NC configuration. |
| 2, 3, 11, 12 (NO1–NO4 / NC1–NC4) | Analog switch terminal | NO pins conduct when INx = HIGH; NC pins conduct when INx = LOW - defined per MAX4538 truth table. |
| 5, 6, 14, 15 (IN1–IN4) | Digital channel control input | TTL/CMOS-compatible (0.8V/2.4V thresholds) - directly driven by microcontroller GPIOs at +5V or ±5V supplies. |
| 7 (EN) | Global enable input | Logic HIGH disables all four switches regardless of INx state - provides system-level fault isolation. |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog current return path - separates digital noise from analog signal paths. |
| 9 (V−) | Negative analog supply | Set to GND for single-supply use; defines lower bound of rail-to-rail analog signal range. |
| 16 (V+) | Positive analog/digital supply | Powers analog switches and internal logic translators; internally tied to substrate. |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement in legacy designs using industry-standard 16-pin SO/QSOP footprints. |
| Rail-to-rail analog signal handling | Supports signals from V− to V+ without clipping - essential for ±5V op-amp interfaces and unipolar sensor outputs. |
| Break-before-make timing | 15ns typical / 50ns max for MAX4538-only - prevents momentary shorting in mixed NO/NC configurations during state transitions. |
| ESD protection | >2kV per Method 3015.7 - enhances robustness in handheld and field-deployable equipment. |
| Low power consumption | <1µW quiescent - extends battery life in portable instrumentation and avionics subsystems. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4538CSE+ | Same electrical specs and pinout; packaged in 16-pin narrow SO (3.9mm × 4.9mm) instead of QSOP (4.0mm × 5.0mm). | Suitable where board space allows wider body but requires same thermal profile and solder-reflow compatibility. | Select MAX4538CSE+ for legacy SO-16 footprint reuse or higher thermal mass requirements. |
| ADG1414BRUZ | Quad SPST, 1.5Ω typical RON, ±15V supply, 16-pin TSSOP; not pin-compatible; higher drive strength and voltage range. | Used in high-precision industrial DAQ where sub-ohm RON and >±10V signal swing are required. | Choose ADG1414BRUZ only when upgrading for lower on-resistance or extended supply range - requires PCB redesign. |
Compared with MAX4538CSE+, the MAX4538CEE+ offers identical functionality in a smaller QSOP footprint ideal for space-constrained portable designs; versus ADG1414BRUZ, it trades higher RON and narrower supply range for lower cost, proven reliability in battery-operated systems, and direct 74HC4316 compatibility.

FAQ
What is the operating temperature range for MAX4538CEE+?
The MAX4538CEE+ is rated for 0°C to +70°C ambient operation, as indicated by the 'C' grade suffix in its ordering code. This commercial-grade temperature range is validated across all electrical parameters including on-resistance, leakage, and switching times - making MAX4538CEE+ suitable for indoor consumer and industrial control applications where ambient extremes are not expected.
Does MAX4538CEE+ support single-supply operation?
Yes, MAX4538CEE+ supports single-supply operation from +2V to +12V with V− connected to GND. At +4.5V, it delivers 200Ω max on-resistance and 100ns turn-on time; analog signal range spans 0V to V+, and logic inputs remain TTL/CMOS-compatible with 0.8V/2.4V thresholds - confirmed in Electrical Characteristics tables for +5V and +3V single-supply conditions.
How does the MAX4538CEE+ differ from MAX4536CEE+ and MAX4537CEE+?
The MAX4538CEE+ integrates two normally open (NO) and two normally closed (NC) switches in one device, whereas MAX4536CEE+ contains four NO switches and MAX4537CEE+ contains four NC switches. All three share identical pinout, supply ranges, timing, and leakage specs - only the default switch state per channel differs, enabling flexible signal path design without changing layout or firmware I/O mapping.
What is the maximum allowable V+ to V− differential voltage for MAX4538CEE+?
The absolute maximum V+ to V− differential voltage for MAX4538CEE+ is 13.0V, as stated in Absolute Maximum Ratings. Exceeding this - even momentarily due to supply overshoot or noise spikes - risks permanent damage. For example, ±6V supplies with ±10% tolerance reach 13.2V and must be derated; ±5V supplies are recommended for margin-safe bipolar operation.
Is MAX4538CEE+ pin-compatible with the 74HC4316?
Yes, MAX4538CEE+ is explicitly designed as pin-compatible with the industry-standard 74HC4316, sharing identical 16-pin DIP/SO/QSOP pin assignments, logic thresholds, and switching behavior. This allows direct substitution in existing designs without PCB modification - confirmed in the General Description and Pin Configurations sections of the official datasheet.
