Product details
Overview
MAX4538CEE 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, 100ns turn-on time at ±4.5V, and <1µW power consumption - used in audio-signal routing and low-voltage data acquisition systems.
For engineers reviewing the MAX4538CEE datasheet, MAX4538CEE pinout, MAX4538CEE application, or MAX4538CEE equivalent, this page delivers verified electrical specs, truth-table-validated switching behavior, package-specific thermal derating, leakage vs. temperature curves, and real-world dynamic performance under ±5V, +5V, and +3V supply conditions.
Technical Context
The MAX4538CEE 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.) prevents transient shorting in mixed NO/NC configurations.
Supply flexibility includes ±2V to ±6V dual supplies or +2V to +12V single supply (V− tied to GND), with TTL/CMOS-compatible inputs (0.8V–2.4V thresholds at +5V) and ESD protection >2kV per Method 3015.7. Analog signal range spans full rail-to-rail (V− to V+), limited only by internal clamp diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rail-flexible designs |
| On-Resistance (RON) | 200Ω max at +4.5V single supply - ensures minimal signal attenuation in precision analog paths |
| RON Match | 6Ω max between channels - critical for matched gain/phase in multi-channel signal routing |
| tON / tOFF | 125ns / 60ns max at ±4.5V - enables fast multiplexing in test equipment and avionics |
| Off-Leakage (ICOM_OFF) | 10nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces |
| Charge Injection | 5pC max - limits voltage glitch at COM node during switching in sample-hold circuits |
| ESD Protection | >2kV HBM - meets MIL-STD-883 Class 3015.7 for rugged handling in manufacturing |
Pinout & Package
MAX4538CEE is housed in a 16-pin QSOP (Quarter Small Outline Package), 0.150" body width, with 0.635mm pitch, rated for 0°C to +70°C operation. Thermal derating is 8.00mW/°C above +70°C (800mW max at +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal logic and switch gates; substrate connection point |
| V− | Negative analog supply | Enables bipolar operation; must tie to GND for single-supply use |
| GND | Digital ground reference | No analog return path - signals float between V+ and V− |
| EN | Global enable input | Logic high disables all four switches simultaneously |
| IN1–IN4 | Individual channel control | Directly drive NO/NC state when EN = low; TTL/CMOS compatible |
| COM1–COM4 | Analog common terminals | Bidirectional signal nodes - interchangeable as input or output |
| NO1, NO4 / NC2, NC3 | Normally open/closed switch terminals | MAX4538-specific pairing: NO on channels 1 & 4, NC on 2 & 3 per truth table |
Key Features
| Feature | Design Value |
|---|---|
| Pin compatibility | Drop-in replacement for 74HC4316 - no PCB redesign required for legacy upgrades |
| Rail-to-rail analog range | Signals swing fully from V− to V+ - eliminates level-shifting in ±5V or +3.3V systems |
| Break-before-make timing | 15ns typical (MAX4538 only) - prevents momentary shorts in mixed NO/NC routing |
| Low power consumption | <1µW quiescent - extends battery life in portable test and avionics equipment |
| Flat on-resistance | 15Ω max variation over signal range - maintains linearity in audio and instrumentation |

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 (+5V to +16.5V); 4.7Ω RON; no dual-supply support | Not suitable for ±5V avionics or bipolar sensor interfaces | Select when only single-rail operation and lower RON are required |
| TS5A3159DCKR | Lower voltage range (+1.65V to +5.5V); 0.75Ω RON; no NC/NO mixing | Limited to low-voltage portable gear; lacks MAX4538's dual NO/NC flexibility | Choose for ultra-low RON in +3.3V systems where mixed topology isn't needed |
Compared with ADG1419BRUZ and TS5A3159DCKR, the MAX4538CEE uniquely supports both dual- and single-supply operation while integrating two NO and two NC switches in one package - essential for compact, flexible routing in battery-powered test and avionics systems where supply headroom and topology diversity matter.

FAQ
What is the operating temperature range for the MAX4538CEE?
The MAX4538CEE is specified for 0°C to +70°C ambient operation. It uses the 'C' grade suffix (as in MAX4538Cxx), confirming commercial temperature range compliance. Derating begins above +70°C at 8.00mW/°C for the QSOP package, with maximum continuous dissipation of 800mW at +70°C.
Does the MAX4538CEE support dual-supply operation?
Yes, the MAX4538CEE supports ±2.0V to ±6.0V dual supplies. V+ and V− must remain within absolute maximum ratings (V+ to V− ≤ 13.0V), and analog signals are constrained to the V− to V+ range. This enables direct interfacing with bipolar op-amps and sensors without level shifting.
How does the MAX4538CEE differ from the MAX4536CEE and MAX4537CEE?
The MAX4538CEE integrates two normally open (NO) and two normally closed (NC) switches in one package, whereas MAX4536CEE has four NO switches and MAX4537CEE has four NC switches. Only MAX4538CEE provides break-before-make timing (15ns typ.), critical for glitch-free switching in mixed-path applications.
What is the on-resistance flatness specification for the MAX4538CEE?
The MAX4538CEE guarantees 15Ω maximum on-resistance flatness (RFLAT(ON)) over the full analog signal range. This means the difference between max and min RON measured across VCOM = V− to V+ is ≤15Ω - ensuring consistent gain and minimal THD in audio and instrumentation paths.
Is the MAX4538CEE pin-compatible with the 74HC4316?
Yes, the MAX4538CEE is explicitly pin-compatible with the industry-standard 74HC4316. Pin assignments for V+, V−, GND, EN, IN1–IN4, COM1–COM4, and NO1/NO4/NC2/NC3 align directly - enabling drop-in replacement without layout changes in existing designs.
