Product details
Overview
MAX4532EAP+ from Maxim Integrated is a triple single-pole/double-throw (SPDT) analog switch IC designed for precision signal routing in mixed-signal systems. It operates from ±2V to ±6V dual supplies or +2V to +12V single supply, features 150Ω max on-resistance (8Ω max matching), rail-to-rail signal handling, and 1nA max off-leakage at +25°C. It is used in avionics data acquisition systems requiring low charge injection (1.5pC typ) and fast switching (tON = 150ns at ±4.5V).
For engineers reviewing the MAX4532EAP+ datasheet, MAX4532EAP+ pinout, MAX4532EAP+ application, or MAX4532EAP+ equivalent, this page delivers verified electrical specs, package mapping to 20-pin SSOP, functional truth table behavior, and real-world selection guidance against industry-standard alternatives - all grounded in Maxim's 1996 datasheet Rev 0a and official ordering information.
Technical Context
The MAX4532EAP+ implements three independent SPDT switches with shared address latching (ADDA/ADDB/ADDC) and dual enable inputs (EN1/EN2), supporting break-before-make operation (4ns min interval). Its CMOS architecture uses V+/V− rails to define analog signal range and drive internal switch gates via logic-level translators - enabling TTL/CMOS-compatible control (0.8V/2.4V thresholds) across supply voltages.
All NO_, NC_, and COM_ terminals are bidirectional and electrically interchangeable; leakage paths flow exclusively between signal pins and V+/V− (not GND), with ESD protection (>2kV per Method 3015.7) integrated on every analog terminal. The device exhibits flat on-resistance vs. VCOM (±4.5V) and stable leakage up to +85°C (50nA max).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches with common COMA/COMB/COMC and NO/NC pairs |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports rail-to-rail analog signals across full range |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in precision sensor or audio paths |
| On-Resistance Matching (∆RON) | 8Ω max between channels - critical for matched gain/phase in differential or multi-channel routing |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves accuracy in high-impedance measurement front-ends |
| Charge Injection | 1.5pC typ - limits voltage glitch on sampled-hold nodes in data acquisition systems |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - enables sub-microsecond channel reconfiguration |
Pinout & Package
MAX4532EAP+ is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS switches and logic; sets upper analog signal limit |
| V− | Negative analog supply | Drives analog switches; connects to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs only; no analog signal path connection |
| LE | Address latch enable | Latches ADDA/ADDB/ADDC state; independent of EN1/EN2 control |
| EN1, EN2 | Complementary switch-enable inputs | Both must be asserted (EN1=LOW, EN2=HIGH) to activate selected switch |
| ADDA, ADDB, ADDC | 3-bit binary address inputs | Select one of eight switch configurations per SPDT group (see Truth Table) |
| COMA, COMB, COMC | Common terminals (SPDT center pins) | Bidirectional - serve as input or output depending on system topology |
| NOA–NOC, NCA–NCC | Normally-open / normally-closed switch terminals | Fully interchangeable; no internal bias - routing defined solely by address and enable |
Key Features
| Feature | Design Value |
|---|---|
| PIN-Compatible with 74HC4353 | Direct drop-in replacement for legacy logic-controlled analog switching without PCB redesign |
| Rail-to-Rail® Signal Handling | Supports analog signals from V− to V+ - eliminates level-shifting in ±5V or +5V systems |
| Break-Before-Make Switching | Guaranteed 4ns minimum interval prevents momentary shorting during channel transitions |
| TTL/CMOS-Compatible Logic | 0.8V/2.4V thresholds ensure reliable control from microcontrollers or FPGAs across supply voltages |

IC Role / Device Role / Timing Role: Three independent SPDTs isolate each sensor leg while sharing address/control lines to reduce I/O count. Use Value: −40°C to +85°C rating ensures reliability in uncontrolled industrial enclosures; 50nA leakage at +85°C maintains measurement integrity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EWP+ | Identical electrical specs and pinout; packaged in 20-pin SO (wide-body) instead of SSOP | SO package offers easier hand-soldering and higher thermal mass; SSOP preferred for space-constrained layouts | Select MAX4532EWP+ when board assembly uses through-hole or standard SO reflow profiles |
| ADG1433BRUZ | Triple SPDT with 4.7Ω typical RON (vs. 150Ω max), but requires ≥±4.5V dual or ≥9V single supply; not pin-compatible | Better performance in low-RON precision instrumentation; incompatible pinout and logic interface (no address latching) | Choose ADG1433BRUZ only when RON < 5Ω is mandatory and control logic can be redesigned for direct channel enables |
Compared with MAX4532EAP+, MAX4532EWP+ offers identical functionality in a larger SO package for simplified assembly, while ADG1433BRUZ provides lower on-resistance at the cost of pin incompatibility and higher supply requirements - making MAX4532EAP+ optimal for legacy-compatible, space-efficient, wide-supply-range designs.

FAQ
What is the operating temperature range for MAX4532EAP+?
The MAX4532EAP+ is specified for operation from −40°C to +85°C. This extended industrial temperature range is confirmed in the Ordering Information table (MAX4532EAP entry) and supported by electrical characteristics tested across TMIN to TMAX. The device maintains 150Ω max on-resistance and 50nA max off-leakage at +85°C, making it suitable for harsh-environment applications like avionics and industrial controls.
Is MAX4532EAP+ pin-compatible with the 74HC4353?
Yes, MAX4532EAP+ is explicitly stated as pin-compatible with the 74HC4353 in the General Description. Pin mapping matches functionally: V+, V−, GND, LE, EN1, EN2, ADDA–ADDC, and all COM/NO/NC terminals align directly. No PCB changes are required when replacing 74HC4353 in existing designs, though supply decoupling should accommodate the CMOS analog switch's dual-rail requirements.
Does MAX4532EAP+ support single-supply operation?
Yes, MAX4532EAP+ supports single-supply operation from +2V to +12V with V− tied to GND. Electrical characteristics are guaranteed across this range - e.g., 150Ω max RON at +5V supply and rail-to-rail signal handling from 0V to V+. The datasheet confirms functionality down to +1.7V (though not guaranteed), and logic thresholds remain TTL/CMOS-compatible even at +12V (≈3.1V high threshold).
What is the maximum allowable voltage on analog pins relative to V+ and V−?
Analog pins (COM/NO/NC) tolerate voltages from V− −0.3V to V+ +0.3V per Absolute Maximum Ratings. Internal ESD diodes clamp excursions beyond these limits, but forward current must be limited to ±20mA. Exceeding these ranges risks permanent damage; operation must stay within the analog signal range of V− to V+ under normal conditions, as validated in Electrical Characteristics tables.
How does the address latching (LE) function interact with enable inputs (EN1/EN2) in MAX4532EAP+?
In MAX4532EAP+, the LE input latches the ADDA/ADDB/ADDC address state independently of EN1 and EN2. Once latched, the selected switch configuration remains active until LE toggles again - even if EN1/EN2 are deasserted. This allows asynchronous address setup and synchronous switching activation, improving timing control in deterministic systems like ATE or digital signal processors interfacing via parallel buses.
