Product details
Overview
MAX4538CSE 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 datasheet, MAX4538CSE pinout, MAX4538CSE application, or MAX4538CSE equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-confirmed pin mapping for narrow SO, and direct alternatives with documented functional trade-offs.
Technical Context
The MAX4538CSE 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.
Supply flexibility includes +2V to +12V single supply (V− = GND) or ±2V to ±6V dual supply, with TTL/CMOS-compatible inputs (0.8V/2.4V thresholds at +5V), <1µW quiescent power, and >2kV HBM ESD protection - enabling battery-operated and avionics-grade deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST: 2× NO + 2× NC, common EN pin - enables selective signal path isolation and redundancy in routing architectures |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal voltage drop and distortion in precision analog paths |
| On-Resistance Match | 6Ω max between channels - critical for matched gain/attenuation in differential or multi-path signal conditioning |
| Turn-On/Off Time | 125ns tON / 60ns tOFF at ±4.5V - supports fast multiplexing in test equipment and real-time signal switching |
| Off-Leakage Current | 10nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and battery-critical systems |
| Analog Signal Range | Rail-to-rail: V− to V+ - accommodates full-supply-swing signals without clipping in ±5V or +5V systems |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V at +5V) - interoperable with microcontrollers, FPGAs, and legacy logic without level shifters |
Pinout & Package
MAX4538CSE is housed in a 16-pin narrow SOIC (Small Outline Integrated Circuit) package, 3.9mm width, 1.27mm pitch, JEDEC MS-012AC compliant, with exposed pad not present and moisture sensitivity level (MSL) 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 (COM1–COM4) | Analog common terminal | Bidirectional signal node shared between NO/NC paths; must be routed with controlled impedance for RF-sensitive applications |
| 2, 3, 11, 12 (NO1–NO4 / NC1–NC4) | Analog switch terminal | NO pins conduct when INx = high & EN = low; NC pins conduct when INx = low & EN = low - logic polarity defined per channel |
| 5, 6, 14, 15 (IN1–IN4) | Digital control input | Directly drives internal level translators; no external pull-up/down required due to defined 0.8V/2.4V thresholds |
| 7 (EN) | Global enable | Active-low; high state forces all switches open regardless of INx states - provides fail-safe shutdown capability |
| 8 (GND) | Digital ground reference | Reference for logic inputs only; no analog current return path - requires separate analog ground plane |
| 9 (V−) | Negative analog supply | Connect to GND for single-supply operation; sets lower bound of analog signal range and P-MOSFET gate drive |
| 16 (V+) | Positive analog/digital supply | Powers analog switches and logic core; internally tied to substrate - decoupling near pin essential for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | 15ns typical, 125ns maximum for MAX4538-only configuration - eliminates signal shorting during NO/NC transition in mixed-mode routing |
| Rail-to-rail analog operation | Supports V− to V+ signal swing (e.g., −5V to +5V or 0V to +5V) - eliminates level-shifting overhead in mixed-supply systems |
| Charge injection | 1pC typical at VCOM = 3V - minimizes DC offset errors in sample-and-hold and precision ADC front-ends |
| Off-isolation | −65dB at 1MHz (50Ω system) - suppresses crosstalk between inactive channels in dense multiplexer layouts |
| ESD robustness | >2kV per Human Body Model (Method 3015.7) - withstands handling and board-level transients without latch-up or parametric shift |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4536CSE | Four NO-only switches; identical pinout, package, and supply specs - no NC functionality | Suitable only for unidirectional path enablement; cannot implement fail-safe default-closed paths | Select when full NO configuration suffices and NC capability is unnecessary |
| ADG1419BRUZ | Quad SPST with 2 NO + 2 NC, but 4.5Ω RON max at ±15V, 16-lead TSSOP, higher supply range (±5V to ±16.5V) | Better performance in high-voltage industrial systems; incompatible pinout and larger footprint | Choose for >±5V operation or lower on-resistance; requires PCB redesign |
Compared with MAX4536CSE, MAX4538CSE adds NC functionality for safety-critical defaults without changing layout; versus ADG1419BRUZ, it offers pin compatibility and lower cost for ±5V/5V systems but trades off voltage range and RON.

FAQ
What is the operating temperature range for MAX4538CSE?
The MAX4538CSE is specified for 0°C to +70°C ambient operation, denoted by the 'C' suffix in its part number. This commercial-grade rating makes it suitable for consumer electronics, portable instrumentation, and non-military industrial systems where extended temperature coverage is not required. The MAX4538ESE variant supports −40°C to +85°C for harsher environments.
Does MAX4538CSE support single-supply operation?
Yes, MAX4538CSE operates from a single +2V to +12V supply with V− connected to GND. At +4.5V, it delivers 200Ω max on-resistance and 100ns turn-on time. Logic inputs remain TTL/CMOS-compatible (0.8V/2.4V thresholds), and analog signals swing rail-to-rail from 0V to V+, enabling simplified power architecture in battery-powered designs.
How does the break-before-make function work in MAX4538CSE?
The MAX4538CSE implements break-before-make exclusively between its paired NO/NC switches (e.g., NO1/NC1), with 15ns typical and 125ns maximum delay. This prevents momentary shorting when toggling between default-open and default-closed states - critical in power sequencing and fault-tolerant signal routing. It does not apply to NO–NO or NC–NC channel pairs.
What package type is used for MAX4538CSE?
MAX4538CSE uses a 16-pin narrow SOIC (Small Outline IC) package, 3.9mm body width, 1.27mm lead pitch, JEDEC MO-153 compliant. Pin 1 identifier is a beveled corner; thermal resistance θJA is 110°C/W. This compact, surface-mount package supports automated assembly and fits high-density PCB layouts typical in portable equipment.
Can MAX4538CSE replace the 74HC4316 in existing designs?
Yes, MAX4538CSE is explicitly pin-compatible with the industry-standard 74HC4316, sharing identical pinout, package outline, and logic-level thresholds at +5V. However, MAX4538CSE adds dual-supply support (±2V to ±6V), lower on-resistance (200Ω vs. ~120Ω for 74HC4316), and guaranteed break-before-make - making it a functional and performance upgrade without layout changes.
