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-specific thermal derating, leakage performance across temperature, and real-world dynamic timing under ±4.5V and +4.5V supply conditions.
Technical Context
The MAX4538CSE+ implements complementary CMOS switch architecture with independent N- and P-channel MOSFETs per channel, driven by logic-level translators that isolate digital control (V+/GND) from analog rails (V+/V−). Its break-before-make timing (15ns typ) is explicitly defined only for the two NC/NO pairs, preventing momentary shorting during state transitions.
ESD protection (>2kV per Method 3015.7) is implemented via bidirectional diodes between each analog pin (NO/NC/COM) and both V+ and V−; leakage current arises solely from reverse-biased diode mismatch, not substrate conduction. Input logic thresholds (0.8V/2.4V at +5V supply) are TTL/CMOS-compatible without external 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-rail systems without level shifters |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures <1% gain error in 20kΩ sensor interfaces |
| On-Resistance Match | 6Ω max between channels - critical for matched-gain multiplexing in instrumentation front-ends |
| Off-Leakage Current | 10nA max at +85°C - preserves accuracy in high-impedance pH or thermocouple measurement paths |
| Turn-On/Off Time | 125ns tON / 60ns tOFF at ±4.5V - enables sub-5MHz multiplexed sampling without settling delay penalties |
| Rail-to-Rail Signal Range | V− to V+ - allows full-scale signal switching in ±5V op-amp stages without clipping |
| Charge Injection | 5pC max - limits voltage glitch to <50µV on 100pF sampling capacitors |
Pinout & Package
MAX4538CSE+ uses a 16-pin narrow SOIC package (5.0mm × 4.0mm body, 1.27mm pitch), rated for 0°C to +70°C operation, with thermal derating of 8.70mW/°C above +70°C (696mW max at +70°C).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | COM1–COM4 | Common analog terminals - bidirectional; may serve as input or output per channel |
| 2, 3, 11, 12 | NO1/NO4, NC2/NC3 | Channel-specific NO/NC terminals - MAX4538 configures pins 2/3 as NO, 11/12 as NC per truth table |
| 5, 6, 14, 15 | IN1–IN4 | Individual channel control inputs - active-high; overridden when EN = high |
| 7 | EN | Global enable - logic high disables all switches (open-circuit state), independent of INx states |
| 8 | GND | Digital ground reference - no analog return path; analog signals float between V+ and V− |
| 9 | V− | Negative analog supply - tied to GND for single-supply use; sets lower signal limit |
| 16 | V+ | Positive analog/digital supply - powers logic core and switch drivers; internally connected to substrate |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility with 74HC4316 | Direct drop-in replacement in legacy designs using industry-standard footprint and logic mapping |
| Break-before-make timing | 15ns typical for NC/NO pairs - prevents transient shorting in relay-replacement power sequencing |
| Low power consumption | <1µW quiescent - extends battery life in portable test equipment with intermittent switching |
| Flat on-resistance | 15Ω max variation over full signal range - maintains linearity in audio gain-control applications |
| TTL/CMOS logic thresholds | 0.8V low / 2.4V high at +5V supply - eliminates need for external logic buffers in microcontroller-driven systems |

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 channels; identical pinout, supply range, and timing; 200Ω RON same spec | Suitable where all paths require make-before-break or always-open default state | Select when system requires uniform NO behavior across all four channels instead of mixed NO/NC. |
| ADG1412BRUZ | Quad SPST, 1.5Ω RON, ±15V rating, but 16-lead TSSOP only; no break-before-make guarantee | Better for high-precision, high-voltage industrial DAQ; incompatible with 74HC4316 layout | Choose for ultra-low RON and higher voltage margin; accept PCB redesign and loss of BbM safety in critical sequencing. |
Compared with MAX4536CSE+, the MAX4538CSE+ provides fail-safe signal routing via its NC/NO pairing, while ADG1412BRUZ trades pin compatibility and BbM timing for lower on-resistance and extended voltage range - making MAX4538CSE+ optimal for space-constrained, legacy-compatible, and sequencing-critical designs.

FAQ
What is the maximum allowable V+ to V− differential voltage for MAX4538CSE+?
The absolute maximum V+ to V− differential voltage for MAX4538CSE+ is 13.0V. Exceeding this - even momentarily due to ±5% supply tolerance overshoot or noise spikes - risks permanent damage. At ±6V nominal, ensure design margins keep peak differential ≤12.8V; derate accordingly for higher-temperature operation where internal leakage increases stress.
Does MAX4538CSE+ support true break-before-make switching on all channels?
MAX4538CSE+ guarantees break-before-make timing only for its two NC/NO pairs (channels 2 & 3), with 15ns typical delay. Channels 1 & 4 operate as independent NO/NC switches without synchronized BbM - their transition timing follows standard tON/tOFF specs (125ns/60ns). This architecture enables safe power sequencing for dual-path circuits while retaining flexibility for non-critical signal routing.
How does leakage current in MAX4538CSE+ vary with temperature and supply configuration?
MAX4538CSE+ off-leakage rises from 1nA at +25°C to 10nA at +85°C under both ±5V dual and +4.5V single supplies. This increase is due to ESD diode reverse-bias conduction, not channel MOSFET leakage. On-leakage remains ≤2nA across temperature - critical for maintaining accuracy in high-Z sensor interfaces like pH electrodes or piezoresistive bridges.
Can MAX4538CSE+ be used with a +3.3V single supply?
Yes - MAX4538CSE+ operates down to +2.0V single supply. At +3.3V, RON increases to 600Ω (typ), tON extends to 300ns, and logic thresholds shift to 0.5V/2.0V. Input drive must meet these adjusted levels; microcontrollers with 3.3V GPIO typically satisfy them. Confirm signal swing stays within 0V to +3.3V and verify THD <0.1% at target frequencies using Figure 12's THD vs. frequency plot.
Is the MAX4538CSE+ pinout compatible with the 74HC4316 in all package variants?
Yes - MAX4538CSE+ in narrow SOIC (CSE) matches the 16-pin 74HC4316 pinout exactly, including V+, GND, V−, EN, IN1–IN4, COM1–COM4, and NO1/NO4/NC2/NC3 assignments. This compatibility extends to DIP and QSOP variants (CPE/CEE), enabling direct substitution without PCB modification in existing 74HC4316 layouts.
