Product details
Overview
MAX4538EEE 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 MAX4538EEE datasheet, MAX4538EEE pinout, MAX4538EEE application, or MAX4538EEE equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-confirmed pin mapping for QSOP-16, and real-world leakage/flatness performance across temperature and supply conditions.
Technical Context
The MAX4538EEE 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 rails (V+/V−). Its break-before-make timing (15ns typ, 125ns max) prevents momentary shorting in mixed NO/NC configurations.
ESD protection (>2kV per Method 3015.7) is integrated via reverse-biased diodes between each analog pin and V+/V−; all analog leakage flows to supply rails-not ground-enabling true floating signal paths. Input thresholds (0.8V/2.4V at +5V) ensure TTL/CMOS compatibility without level-shifting.
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 industrial systems |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in precision sensor interfaces |
| RON Flatness | 10Ω max over full signal range - preserves linearity in audio and instrumentation applications |
| Off-Leakage Current | 10nA max at +85°C - enables reliable operation in high-impedance sample-and-hold circuits |
| Switching Speed | tON = 100ns, tOFF = 80ns at ±4.5V - suitable for multiplexing up to ~5MHz analog signals |
| Charge Injection | 5pC typ - limits voltage glitch in ADC front-end sampling networks |
| ESD Rating | >2kV per Method 3015.7 - meets basic handling robustness for portable equipment assembly |
Pinout & Package
MAX4538EEE is supplied in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), RoHS-compliant, with exposed pad not present. Pin functions are validated per Maxim's official pin configuration diagram (Rev 0, 11/96).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal | Bi-directional signal path hub; connects to either NO or NC depending on logic state |
| 2, 3, 11, 12 (NO1–NO4 / NC1–NC4) | Normally open or normally closed switch terminal | MAX4538EEE uses pins 2/3 as NO, 11/12 as NC - fixed per device variant, not configurable |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input per channel | Directly drives individual switch gate logic; referenced to V+/GND, not V− |
| 7 (EN) | Global enable/disable input | Logic-high disables all four switches simultaneously - critical for power sequencing and fault isolation |
| 8 (GND) | Digital ground reference | No analog return path; all analog signals float between V+ and V− rails |
| 9 (V−) | Negative analog supply | Must be connected to GND for single-supply use; sets lower bound of analog signal range |
| 16 (V+) | Positive analog/digital supply | Powers internal logic translators and switch gates; substrate-connected for latch-up immunity |
Key Features
| Feature | Design Value |
|---|---|
| Two NO + two NC topology | Enables simultaneous signal routing and fail-safe path selection - e.g., bypass vs. filter insertion in audio chains |
| Rail-to-rail analog operation | Supports full V− to V+ signal swing without clipping - essential for ±5V op-amp interfacing and unbuffered sensors |
| Break-before-make timing | Guaranteed 15ns minimum delay between NC deactivation and NO activation - prevents cross-conduction in mixed-path designs |
| TTL/CMOS-compatible inputs | Operates directly from +5V microcontrollers or FPGAs without external level shifters |
| Low 1µW quiescent power | Reduces thermal load and extends battery life in always-on monitoring nodes |

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 (+3V to +40V); 3.8Ω RON; no NC/NO mix; 16-TSSOP | Higher voltage range but lacks dual-supply support and mixed NO/NC topology | Select when operating above +12V or requiring ultra-low RON, but redesign needed for NO/NC functionality |
| TS5A3159DCKR | Single-supply only (+1.65V to +5.5V); 0.75Ω RON; all-NO; SC70-6 | Lower RON and smaller footprint, but only two NO switches, no enable pin, no NC capability | Choose for space-constrained, low-RON, single-pole routing where fail-safe NC paths are unnecessary |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4538EEE uniquely provides dual-supply operation, integrated break-before-make timing, and factory-configured NO/NC pairing - making it irreplaceable in bipolar-rail audio routing and fault-tolerant sensor interface designs.

FAQ
What is the operating temperature range for MAX4538EEE?
The MAX4538EEE is rated for -40°C to +85°C ambient operation, confirmed by Maxim's Ordering Information table listing "MAX4538EEE" under the "-40°C to +85°C" temperature grade. This extended range supports deployment in automotive cabin modules, industrial PLC I/O cards, and outdoor portable instrumentation where thermal cycling is expected. The device maintains specified RON flatness, leakage, and switching speed across this full range.
Does MAX4538EEE support dual-supply operation?
Yes, MAX4538EEE supports dual-supply operation from ±2.0V to ±6.0V, as explicitly stated in the General Description and Electrical Characteristics tables. When using dual supplies, V+ connects to the positive rail, V− to the negative rail, and GND serves only as the digital logic reference - enabling true bipolar signal handling from V− to V+ without level-shifting circuitry.
How is the NO/NC configuration implemented in MAX4538EEE?
The MAX4538EEE has two fixed NO switches (pins NO1/NO2) and two fixed NC switches (pins NC3/NC4), as shown in the functional diagram and truth table. This configuration is hardwired in silicon - not software-selectable - and enables simultaneous path selection and safety-critical default states (e.g., NC path remains closed during power loss or logic fault).
What is the maximum allowable V+ to V− differential voltage for MAX4538EEE?
The absolute maximum V+ to V− differential voltage for MAX4538EEE is 13.0V, per the Absolute Maximum Ratings table. Exceeding this - even momentarily due to supply overshoot or noise - risks permanent damage. Designers must ensure ±6V supplies include margin (e.g., ±5.5V max) or implement clamping to stay within the 13.0V limit.
Is MAX4538EEE pin-compatible with the 74HC4316?
Yes, MAX4538EEE is pin-compatible with the industry-standard 74HC4316, as confirmed in the General Description. This allows drop-in replacement in existing layouts using 16-pin SO or QSOP footprints, preserving PCB design while upgrading to lower on-resistance, rail-to-rail operation, and dual-supply capability - provided V− is properly decoupled and logic thresholds are verified.
