Product details
Overview
MAX4538CPE from Maxim Integrated is a quad SPST analog switch IC 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 MAX4538CPE datasheet, MAX4538CPE pinout, MAX4538CPE application, or MAX4538CPE equivalent, this page delivers verified electrical specs, truth-table–validated switching behavior, package-confirmed pin mapping for 16-pin PDIP, thermal performance across 0°C to +70°C, and direct alternatives with documented channel configuration differences.
Technical Context
The MAX4538CPE implements four independently controlled CMOS transmission gates driven by logic-level translators that convert TTL/CMOS inputs into complementary V+ and V− gate drive signals. Its dual-supply architecture (±2V to ±6V) or single-supply operation (+2V to +12V) enables rail-to-rail analog signal switching without level-shifting circuitry.
Each switch features matched on-resistance (≤6Ω max mismatch), flat on-resistance (≤15Ω variation over signal range), and break-before-make timing (5ns min, 15ns typ) exclusive to the MAX4538 variant - critical for preventing momentary shorts in mixed NO/NC configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single or ±2V to ±6V dual - supports battery-powered and industrial bipolar rails |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in 50Ω–600Ω systems |
| On-Resistance Match | 6Ω max difference between channels - preserves gain/phase matching in multi-channel signal paths |
| Turn-On/Off Time | 125ns tON / 60ns tOFF at ±4.5V - enables sub-10MHz multiplexing with <1% settling error |
| Off-Leakage Current | 10nA max at +85°C - maintains high-impedance isolation in precision sensor front-ends |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V supply - interoperates directly with 74HC, 74AHC, and microcontroller GPIO |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level ESD events without latch-up |
Pinout & Package
MAX4538CPE uses a 16-pin plastic DIP (PDIP) package with 0.300″ wide body, 0.100″ lead pitch, and through-hole mounting. Pin 1 is bottom-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives P-channel gates and powers internal logic; substrate-connected |
| V− | Negative analog supply | Drives N-channel gates; tied to GND for single-supply use |
| GND | Digital ground reference | No analog return path - all signals float between V+ and V− |
| EN | Global enable input | High disables all four switches simultaneously; TTL/CMOS compatible |
| IN1–IN4 | Individual channel control inputs | Active-high for NO channels (1,4), active-low for NC channels (2,3) |
| COM1–COM4 | Analog common terminals | Bidirectional I/O nodes - interchangeable as input or output |
| NO1, NO4 | Normally open switch outputs | Connect to COMx only when corresponding INx = high and EN = low |
| NC2, NC3 | Normally closed switch outputs | Connect to COMx when INx = low and EN = low; disconnect on INx high |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | 5ns minimum interval prevents short-through during NO/NC transition in MAX4538-specific dual-mode operation |
| Rail-to-rail signal handling | Supports analog voltages from V− to V+ - eliminates external clamping diodes in ±5V or +3.3V systems |
| Charge injection | 1pC typical - minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors) |
| Off-isolation | −65dB at 1MHz - suppresses crosstalk between adjacent channels in dense PCB layouts |
| Power consumption | <1µW quiescent - extends battery life in portable test equipment and avionics subsystems |
Applications
| Audio-Signal Routing | Low-Voltage Data Acquisition |

IC Role / Device Role / Timing Role: High-reliability SPST switch enabling repeatable, low-crosstalk routing of calibration references. Use Value: 125ns tON ensures <100ns path reconfiguration latency; 15Ω RON flatness maintains amplitude accuracy across full ±4.5V range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4536CPE | Four NO-only channels; no NC functionality; identical pinout and timing | Suitable only where all paths require normally open behavior | Select when system requires uniform NO topology and no break-before-make sequencing |
| MAX4537CPE | Four NC-only channels; no NO functionality; identical pinout and timing | Applicable where default-closed paths simplify power-up state management | Choose when fail-safe closure (e.g., safety interlocks) is required on power loss |
Compared with MAX4536CPE and MAX4537CPE, the MAX4538CPE uniquely integrates mixed NO/NC topology with validated break-before-make timing - enabling fault-tolerant signal routing in systems requiring both default-open and default-closed paths without external logic.

FAQ
What is the operating temperature range for MAX4538CPE?
The MAX4538CPE is rated for 0°C to +70°C ambient operation. This commercial-grade specification matches the 'C' suffix in the part number and is validated per Maxim's datasheet ABSOLUTE MAXIMUM RATINGS and ELECTRICAL CHARACTERISTICS tables under 'C' temperature column. The device uses silicon process and packaging qualified for this range, with leakage, timing, and on-resistance parameters fully characterized across the span.
Does MAX4538CPE support single-supply operation?
Yes, MAX4538CPE operates from a single +2V to +12V supply when V− is connected to GND. Electrical characteristics including 200Ω max on-resistance, 100ns turn-on time, and 10nA off-leakage at +85°C are specified under +4.5V to +5.5V single-supply conditions. The internal level translators ensure TTL/CMOS compatibility without external level shifters.
How does the MAX4538CPE differ from MAX4536CPE and MAX4537CPE?
The MAX4538CPE integrates two NO and two NC switches in one package with verified break-before-make timing, whereas MAX4536CPE contains four NO switches and MAX4537CPE contains four NC switches. All three share identical pinout, supply ranges, and timing specs, but only MAX4538CPE enables mixed-mode routing - critical for applications requiring both default-open and default-closed paths.
What package type is used by MAX4538CPE?
MAX4538CPE uses a 16-pin plastic DIP (dual in-line package) with 0.300″ body width and 0.100″ lead pitch, as confirmed in the Ordering Information table and Package Information section of the datasheet. This through-hole package is designated 'CPE' in Maxim's naming convention and is distinct from SO ('CSE') and QSOP ('CEE') variants.
Is MAX4538CPE pin-compatible with industry-standard logic devices?
Yes, MAX4538CPE is explicitly pin-compatible with the 74HC4316 quad analog switch, as stated in the General Description. Pin-for-pin mapping includes V+, V−, GND, EN, IN1–IN4, COM1–COM4, and NO1/NO4 or NC2/NC3 terminals - enabling drop-in replacement in existing 74HC4316-based designs without layout changes.
