Product details
Overview
The MAX4532CAP from Maxim Integrated is a low-voltage CMOS analog switch IC configured as three independent single-pole/double-throw (SPDT) switches, operating from ±2V to ±6V dual supplies or +2V to +12V single supply, with 150Ω max on-resistance, 8Ω max on-resistance matching, rail-to-rail signal handling, and 1nA COM-off leakage at +25°C - used in precision audio-signal routing and battery-operated test equipment.
For engineers reviewing the MAX4532CAP datasheet, MAX4532CAP pinout, MAX4532CAP application, or MAX4532CAP equivalent, this page delivers verified electrical specs, SSOP-20 package details, real-world timing behavior (tON = 150ns at ±4.5V), ESD robustness (>2kV), and direct alternatives for analog switching in avionics and ATE systems.
Technical Context
The MAX4532CAP implements three fully independent SPDT switches with separate COM/NO/NC terminals per channel, each controlled by a shared 3-bit address bus (ADDA, ADDB, ADDC) and dual enable inputs (EN1, EN2). Address latching via LE allows static channel selection without continuous address drive.
All switches feature matched on-resistance flatness (≤13Ω), break-before-make switching (4–10ns interval), and TTL/CMOS-compatible logic thresholds (0.8V/2.4V) across supply ranges. Signal paths support bidirectional rail-to-rail analog operation with <1.5pC charge injection and -65dB off-isolation at 1MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches (COMA/NOA/NCA, COMB/NOB/NCB, COMC/NOC/NCC) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables portable and industrial rail-flexible designs |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in low-level sensor/audio paths |
| On-Resistance Matching (∆RON) | 8Ω max between channels - critical for balanced differential switching and multiplexer accuracy |
| Off-Leakage Current | 1nA max at TA = +25°C (COM-off) - preserves DC integrity in high-impedance measurement circuits |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - supports fast channel reconfiguration in data acquisition |
| ESD Protection | >2kV per Method 3015.7 - enhances reliability in handling-sensitive production and field environments |
Pinout & Package
MAX4532CAP is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, 7.2mm × 5.3mm body size, and exposed pad not present. Pin functions are validated per Maxim's official pin description table and top-view diagrams.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switches and internal logic; sets upper analog signal limit (V+) |
| V- | Negative supply input | Drives analog switches; sets lower analog signal limit (V-); connect to GND for single-supply use |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path and supply rails |
| LE | Address latch enable | Edge-triggered latch captures ADDA/ADDB/ADDC state; enables static channel hold |
| EN1, EN2 | Complementary enable inputs | Both must be asserted (EN1=LOW, EN2=HIGH) to activate selected switch; provides safety interlock |
| ADDA, ADDB, ADDC | 3-bit binary address inputs | Select one of eight possible switch configurations across three SPDTs per truth table |
| COMA, NOA, NCA | Channel A SPDT terminals | COMA is common; NOA = normally open; NCA = normally closed - fully bidirectional |
| COMB, NOB, NCB | Channel B SPDT terminals | Electrically isolated from Channel A; identical pin behavior and performance |
| COMC, NOC, NCC | Channel C SPDT terminals | Third independent SPDT; matches Channels A/B in RON, leakage, and timing specs |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V- to V+ without clipping - essential for full-scale sensor and audio interfaces |
| Pin compatibility with 74HC4353 | Direct drop-in replacement for legacy TTL/CMOS analog switch designs - no PCB redesign needed |
| Address latching with LE input | Eliminates need for continuous address bus drive - reduces MCU GPIO overhead and noise coupling |
| Break-before-make switching | Guaranteed 4–10ns isolation gap prevents momentary shorting during channel transitions |
| Low power consumption | <1µW quiescent power - extends battery life in portable instrumentation and handheld testers |
| TTL/CMOS logic compatibility | Fixed 0.8V/2.4V thresholds work across +3V, +5V, and +12V supplies - simplifies mixed-voltage system integration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog SPDT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532CWP | Same die, 20-pin SO package (1.27mm pitch, 12.8mm × 7.5mm); higher thermal resistance (10.00mW/°C derating) | Better suited for prototyping and through-hole assembly; less board-area efficient than SSOP | Select when SO footprint compatibility or hand-soldering is required over space-constrained layouts |
| ADG1434BRUZ | Quad SPDT, 4.5Ω RON typ, ±15V supply capable, but no address latching or LE input | Requires external logic for channel control; superior RON but lacks integrated decode/latch functionality | Choose when ultra-low on-resistance or extended voltage range outweighs need for embedded addressing |
Compared with MAX4532CWP and ADG1434BRUZ, the MAX4532CAP offers optimal balance of integrated address decoding, SSOP space efficiency, and guaranteed break-before-make timing - making it preferred for compact, microcontroller-driven analog routing where layout area and GPIO count are constrained.

FAQ
What supply voltages does the MAX4532CAP support?
The MAX4532CAP operates from ±2V to ±6V dual supplies or +2V to +12V single supply (with V- tied to GND). At ±4.5V, it achieves 150ns turn-on time and 150Ω max on-resistance. The MAX4532CAP maintains rail-to-rail analog signal handling across all supported ranges, and logic inputs remain TTL/CMOS-compatible due to fixed 0.8V/2.4V thresholds.
Does the MAX4532CAP require external pull-up or pull-down resistors on address pins?
No, the MAX4532CAP does not require external biasing on ADDA, ADDB, or ADDC - its digital inputs have guaranteed 0.8V low and 2.4V high thresholds with input currents under ±1.0µA. The MAX4532CAP functions correctly with direct MCU GPIO connection, and floating inputs are avoided by design due to defined logic thresholds across temperature and supply.
How is channel selection implemented in the MAX4532CAP?
The MAX4532CAP uses a 3-bit binary address (ADDA, ADDB, ADDC) decoded internally to select one of eight switch states across its three SPDTs. The LE (latch enable) input captures the address on its rising edge, allowing static channel hold without continuous bus driving. The MAX4532CAP requires complementary EN1 (active-low) and EN2 (active-high) enables to activate the selected configuration.
Can the MAX4532CAP handle bipolar analog signals in single-supply mode?
Yes - in single-supply mode (V- = GND), the MAX4532CAP supports analog signals from 0V to V+, including AC-coupled bipolar waveforms centered at V+/2. Its rail-to-rail architecture and CMOS switch topology allow full-swing operation, and the MAX4532CAP maintains 150Ω max on-resistance and <1.5pC charge injection under these conditions, preserving signal integrity for audio and sensor applications.
What is the maximum signal frequency supported by the MAX4532CAP?
The MAX4532CAP delivers flat insertion loss up to 50MHz in 50Ω systems, with -65dB off-isolation at 1MHz decreasing at ~20dB/decade above that. For high-frequency routing, the MAX4532CAP's 26pF COM-on capacitance and 150ns switching make it suitable for baseband and low-MHz instrumentation, but not RF signal paths. Layout-dependent peaking occurs above 20MHz, so careful PCB design is recommended.
