Product details
Overview
MAX4532EWP from Maxim Integrated is a low-voltage, CMOS analog switch IC configured as three independent single-pole/double-throw (SPDT) switches with address latching and dual enable inputs. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 150Ω max on-resistance (at +5V), matches channels within 8Ω, and handles rail-to-rail analog signals up to ±4.5V. It is used in precision audio-signal routing and ATE equipment where channel isolation and low charge injection are critical.
For engineers reviewing the MAX4532EWP datasheet, MAX4532EWP pinout, MAX4532EWP application, or MAX4532EWP equivalent, key selection criteria include its -40°C to +85°C extended temperature rating, 20-pin wide SO package, break-before-make timing (4–10 ns), <1 µW quiescent power, and guaranteed 1nA COM-off leakage at +25°C - all verified under dual-supply operation.
Technical Context
The MAX4532EWP implements three fully independent SPDT switches, each with dedicated COM, NO, and NC terminals. Switch control uses three address bits (ADDA, ADDB, ADDC), two complementary enable inputs (EN1, EN2), and a latch-enable (LE) for synchronous channel selection. All digital inputs meet TTL/CMOS thresholds (0.8V low / 2.4V high) across supply ranges.
Its internal architecture features matched P- and N-channel MOSFET pairs per switch path, enabling rail-to-rail signal handling and low distortion (<0.025% THD). ESD protection exceeds 2kV per Method 3015.7, and dynamic performance includes tON = 150 ns and tOFF = 120 ns at ±4.5V, with 1.5 pC typical charge injection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports industrial and battery-powered systems with flexible biasing. |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in precision analog paths. |
| RON Matching | 8Ω max between channels - critical for matched gain/phase in differential or multi-channel routing. |
| Off-Leakage Current | 1nA at TA = +25°C, 50nA at TA = +85°C - preserves DC accuracy in high-impedance sensor interfaces. |
| Charge Injection | 1.5 pC typical - limits voltage glitch on sampled nodes in data acquisition front-ends. |
| Switching Speed | tON = 150 ns, tOFF = 120 ns at ±4.5V - enables reliable multiplexing in sub-10 MHz signal chains. |
| ESD Protection | >2 kV per Method 3015.7 - enhances robustness in handling and board-level integration. |
Pinout & Package
MAX4532EWP is housed in a 20-pin wide SO (Small Outline) package, 7.6 mm × 12.8 mm body, 1.27 mm pitch, with exposed pad not connected. Pin 1 is top-left corner (notch-mark side), pin count increases left-to-right, top row then bottom row.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal logic and switch gates; sets upper analog signal limit (up to V+). |
| NO0–NO7 | Analog switch normally-open terminals | Three SPDT sections: NOA/NOB/NOC assigned to COMA/COMB/COMC respectively (see Truth Table). |
| COM | Common terminal (shared label; actual pins: COMA, COMB, COMC) | Each COM connects to one SPDT section; bidirectional signal path with rail-to-rail capability. |
| N.C. | Not internally connected | Pins 3 and 14 are unused - no internal connection; may be left floating or grounded per layout needs. |
| EN1 / EN2 | Complementary enable logic inputs | Both must be asserted (EN1=low, EN2=high) to activate switching; enables power-gating of sections. |
| ADDA / ADDB / ADDC | 3-bit binary address inputs | Selects active SPDT path per section (e.g., ADDA=0/ADDB=0/ADDC=0 → COMA–NOA, COMB–NOB, COMC–NOC). |
| LE | Latch-enable input | Edge-triggered; captures address bits on rising edge to freeze channel selection asynchronously. |
| GND | Digital ground reference | Reference for logic inputs only; analog signal paths are isolated from GND (no analog ground tie). |
| V− | Negative analog supply | For dual-supply operation; connect to GND for single-supply use; sets lower analog signal limit (down to V−). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® signal handling | Analog signals swing from V− to V+ without clipping - essential for full-scale audio and sensor interfaces. |
| Break-before-make switching | 4–10 ns guaranteed interval prevents momentary shorting between paths - avoids signal corruption during reconfiguration. |
| Address latching with LE | Eliminates need for continuous address stability; allows asynchronous control via microcontroller GPIO. |
| Pin compatibility with 74HC4353 | Direct drop-in replacement for legacy TTL/CMOS mux designs - reduces redesign effort and qualification time. |
| Low 1.5 pC charge injection | Minimizes voltage transient on high-Z nodes - improves accuracy in sample-and-hold and ADC front-end circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog SPDT switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532CPD | Same die, 0°C to +70°C temp grade, 20-pin plastic DIP package | Limited to commercial-temperature environments; larger footprint; no moisture sensitivity level (MSL) concern | Choose for lab prototypes or non-extended-temp cost-sensitive designs where SO packaging isn't required. |
| ADG1434BRUZ | Quad SPDT, 1.5 Ω RON (lower), but requires ≥±4.5V dual or ≥9V single supply; no address latching | Higher precision, no LE support - demands continuous address hold; incompatible pinout and logic interface | Prefer when ultra-low on-resistance dominates over latching and supply flexibility; requires full schematic/layout revision. |
Compared with MAX4532CPD, the MAX4532EWP offers extended temperature operation and smaller SO packaging, while ADG1434BRUZ trades latching and supply versatility for lower RON - making MAX4532EWP optimal for ruggedized, microcontroller-driven routing where deterministic channel hold and wide supply range are mandatory.

FAQ
What is the operating temperature range of the MAX4532EWP?
The MAX4532EWP is rated for operation from -40°C to +85°C. This extended temperature grade is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet. It is designed for industrial and avionics applications where ambient conditions exceed commercial-grade limits. The MAX4532EWP maintains specified RON, leakage, and timing performance across this full range.
Does the MAX4532EWP support single-supply operation?
Yes, the MAX4532EWP supports single-supply operation from +2V to +12V. In this configuration, V− is connected to GND. The device retains rail-to-rail analog signal handling (0V to V+), TTL/CMOS-compatible logic thresholds, and full functionality of address latching and dual enable inputs. Performance parameters such as RON and leakage are characterized under both single- and dual-supply conditions.
How many independent switches does the MAX4532EWP contain?
The MAX4532EWP contains three independent single-pole/double-throw (SPDT) switches. Each has dedicated COM, NO, and NC terminals (labeled COMA/NOA/NCA, COMB/NOB/NCB, COMC/NOC/NCC), controlled by shared ADDA/ADDB/ADDC address bits and EN1/EN2 enables. The Truth Table explicitly defines all nine possible switch combinations across the three sections.
Is the MAX4532EWP pin-compatible with any standard logic devices?
Yes, the MAX4532EWP is pin-compatible with the industry-standard 74HC4353 analog multiplexer. This compatibility is stated in the General Description and confirmed by identical pin functions (e.g., V+, GND, V−, EN1, EN2, ADDA–ADDC, LE, COM/NO/NC assignments) and 20-pin wide SO footprint. No PCB changes are required when upgrading from 74HC4353 to MAX4532EWP in existing designs.
What is the maximum on-resistance specification for the MAX4532EWP?
The MAX4532EWP has a maximum on-resistance (RON) of 150Ω when operated with a +5V single supply, as specified in the Electrical Characteristics table under "Single +5V Supply" conditions. At ±4.5V dual supply, RON is typically 75Ω. The datasheet guarantees RON matching between channels to within 8Ω, ensuring consistent signal path impedance across all three SPDT sections.
