Product details
Overview
MAX4538EPE 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/80ns turn-on/turn-off times at ±4.5V - used in audio-signal routing and low-voltage data acquisition systems.
For engineers reviewing the MAX4538EPE datasheet, MAX4538EPE pinout, MAX4538EPE application, or MAX4538EPE equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-specific thermal derating, leakage vs. temperature curves, and direct alternatives for dual-supply analog multiplexing designs.
Technical Context
The MAX4538EPE implements four independent CMOS transmission gates driven by logic-level translators that convert TTL/CMOS inputs into complementary V+ and V− gate drive signals. Its internal architecture uses paralleled N- and P-channel MOSFETs per switch to achieve rail-to-rail conduction and flat on-resistance (≤10Ω) across the full analog range.
Switch control follows a break-before-make sequence for the NO/NC pairs (tBBM = 5–15ns), preventing momentary shorting during state transitions. All analog terminals feature ESD protection diodes to V+ and V−, limiting signal excursion to (V− − 0.3V) to (V+ + 0.3V) and contributing to off-leakage current that remains ≤10nA at +85°C.
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 industrial bipolar rails |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in precision sensor interfaces |
| On-Resistance Match | 6Ω max between channels - critical for matched gain paths in differential signal routing |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance sampling circuits |
| Turn-On / Turn-Off Time | 125ns / 60ns max at ±4.5V - enables sub-microsecond channel switching in automated test equipment |
| Logic Compatibility | 0.8V to 2.4V thresholds at +5V supply - interoperates directly with 74HC, 74AHC, and microcontroller GPIOs |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level transients without latch-up |
Pinout & Package
MAX4538EPE is housed in a 16-pin plastic DIP (dual in-line package) with 0.300″ wide body, 0.100″ lead pitch, and JEDEC MS-001 compliant footprint. Thermal derating is 10.53mW/°C above +70°C; max continuous power dissipation is 842mW at TA = +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal | Bidirectional signal path node; interchangeable as input or output; must remain within V− to V+ range |
| 2, 3, 11, 12 (NO1–NO4 / NC1–NC4) | Analog switch terminal | NO pins conduct when INx = high; NC pins conduct when INx = low; both types support rail-to-rail signals |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input | Individually selects switch state; referenced to GND; drives internal level translators |
| 7 (EN) | Global enable input | Logic high disables all switches regardless of INx states - provides system-level channel shutdown |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog return path - analog signals float between V+ and V− |
| 9 (V−) | Negative analog supply | Connect to GND for single-supply operation; sets lower bound of analog signal range |
| 16 (V+) | Positive analog/digital supply | Powers analog switches and logic core; internally tied to substrate; defines upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | 5–15ns guaranteed for NO/NC pairs - prevents signal shorting during transition in mixed-signal routing |
| Rail-to-rail analog operation | VCOM, VNO, VNC swing from V− to V+ - eliminates level-shifting in ±5V or +3.3V data acquisition front-ends |
| Charge injection | 1pC typical - minimizes sampling error in switched-capacitor ADC drivers and sample-hold circuits |
| Channel-to-channel crosstalk | −75dB at 1MHz - maintains signal integrity in multi-channel audio mixing and instrumentation |
| Off-isolation | −65dB at 1MHz - suppresses leakage between inactive channels in high-density analog matrices |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | 4-channel, 12V max supply, 2.7Ω RON, SPI interface, no common enable | Requires serial control; better RON but higher cost and layout complexity | Select when ultra-low on-resistance and digital programmability outweigh need for simple parallel control. |

FAQ
What is the operating temperature range of the MAX4538EPE?
The MAX4538EPE is rated for −40°C to +85°C ambient operation, validated per the E-grade qualification standard. This extended range supports deployment in industrial control cabinets, outdoor test gear, and avionics bays where passive cooling and wide thermal swings occur. The device's leakage currents, on-resistance, and switching times are fully specified across this interval, with no derating required up to +85°C.
Does the MAX4538EPE support dual-supply operation, and what are the limits?
Yes, the MAX4538EPE operates from ±2.0V to ±6.0V dual supplies, with absolute maximum V+ to V− differential of 13.0V. It is critical to ensure combined tolerances (e.g., ±5% on ±5V rails) do not exceed this limit - 5.25V/−5.25V yields 10.5V, which is safe, but ±6V with 10% overshoot reaches 13.2V and risks damage. The device draws only 0.05µA typical supply current per rail under static conditions.
How does the MAX4538EPE differ from the MAX4536EPE and MAX4537EPE?
The MAX4538EPE integrates two normally open (NO) and two normally closed (NC) SPST switches in one package, whereas MAX4536EPE contains four NO switches and MAX4537EPE contains four NC switches. All three share identical pinouts, supply ranges, timing specs, and thermal characteristics. The MAX4538EPE's mixed topology enables break-before-make functionality in signal path selection without external logic, unlike the uniform-switch variants.
Can the MAX4538EPE be used with a +3.3V single supply?
Yes, the MAX4538EPE functions with +3.3V single supply (V− = GND), delivering 600Ω typical on-resistance and 300ns/250ns turn-on/turn-off times. Input logic thresholds scale with V+, remaining compatible with 3.3V CMOS levels (VINH ≈ 2.0V, VINL ≈ 0.5V). However, analog signal range is limited to 0V to +3.3V, and off-isolation degrades to −44dB at 10MHz - verify bandwidth requirements against the +3.3V electrical characteristics table.
Is the MAX4538EPE pin-compatible with the 74HC4316?
Yes, the MAX4538EPE is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4316, sharing identical 16-pin DIP, SO, and QSOP footprints and pin assignments. Unlike the 74HC4316, the MAX4538EPE adds rail-to-rail analog operation, lower leakage (<10nA at +85°C vs. ~100nA), and enhanced ESD protection (>2kV vs. ~200V), while maintaining TTL/CMOS logic compatibility at +5V.
