Product details
Overview
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, and rail-to-rail signal handling - used in precision audio-signal routing and avionics data switching.
For engineers reviewing the MAX4532CAP+ datasheet, MAX4532CAP+ pinout, MAX4532CAP+ application, or MAX4532CAP+ equivalent, this page delivers verified electrical specs, package mapping to 20-pin SSOP, truth-table–validated switching behavior, and direct alternatives for SPDT analog switch replacement in battery-powered and high-isolation 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 input ensures stable channel selection without continuous address hold.
Its CMOS architecture uses complementary switch-enable logic and internal level translators to drive analog gates directly from TTL/CMOS-compatible digital inputs (0.8V/2.4V thresholds), supporting both single-supply (+5V) and bipolar (±4.5V) operation while maintaining <1nA off-leakage at +25°C and >2kV ESD protection per Method 3015.7.
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 - supports rail-to-rail analog signals across full supply range |
| On-Resistance (RON) | 150Ω max at +5V supply - defines worst-case voltage drop and power loss in signal path |
| RON Matching | 8Ω max between channels - ensures consistent gain/attenuation across multiplexed paths |
| Off-Leakage Current | 1nA max at TA = +25°C - preserves signal integrity in high-impedance sensor or audio circuits |
| Enable Turn-On Time | 150ns at ±4.5V - enables fast channel switching in ATE and real-time test equipment |
| ESD Protection | >2kV per Method 3015.7 - meets industrial handling requirements without external protection |
Pinout & Package
MAX4532CAP+ is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, body size 7.2mm × 5.3mm, and exposed pad not present. Pin 1 marked via dot or beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS gates and sets upper analog signal limit; must be ≥ |V−| for bipolar operation |
| V− | Negative analog supply | Reference for negative analog swing; connect to GND for single-supply use |
| GND | Digital ground reference | Return path for logic circuitry only; isolated from analog signal paths |
| LE | Address latch enable | Edge-triggered input that freezes ADDA/ADDB/ADDC state for stable channel selection |
| EN1 / EN2 | Complementary enable inputs | Both must be asserted (EN1=low, EN2=high) to activate switches; provides fault-safe control |
| ADDA / ADDB / ADDC | 3-bit binary address inputs | Select one of eight possible switch configurations per channel (e.g., COMA–NOA or COMA–NCA) |
| COMA / COMB / COMC | Analog common terminals | Center pins of each SPDT; bidirectional - may serve as input or output |
| NOA / NOB / NOC | Normally open switch terminals | Connected to COM when selected; otherwise high-impedance (off-state leakage <1nA) |
| NCA / NCB / NCC | Normally closed switch terminals | Connected to COM when unselected; breaks before make during transition (tBBM = 4ns typ) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Analog signals swing from V− to V+ without clipping - essential for ±5V audio and sensor interfaces |
| Break-before-make switching | Guaranteed tBBM ≥ 4ns prevents momentary shorting between NO and NC paths during transition |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds ensure reliable operation with +5V microcontrollers and FPGAs without level shifters |
| Low charge injection (1.5pC typ) | Minimizes voltage glitch on high-impedance nodes during switching - critical for precision DAC/ADC muxing |
| Small 20-pin SSOP footprint | 7.2mm × 5.3mm package saves board space vs. legacy DIP/SO while maintaining thermal performance |
Applications
| Audio-Signal Routing | Avionics Data Switching |
|---|---|
|
Use Scenario: Selecting between multiple microphone preamp outputs or line-level sources in portable mixing consoles. IC Role / Device Role / Timing Role: SPDT analog switch providing low-distortion, low-crosstalk signal path selection with no DC bias dependency. Use Value: 150Ω RON and <−92dB crosstalk preserve signal fidelity; rail-to-rail operation avoids clipping on ±3V audio peaks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EAP+ | Same functionality and pinout, but rated for −40°C to +85°C industrial temperature range | Required for extended-temperature avionics or automotive under-hood use | Select MAX4532EAP+ when operating beyond 0°C to +70°C ambient limits |
| ADG1434BRUZ | Quad SPDT, 4.7Ω typical RON, ±15V tolerant, but no address latching or dual enable logic | Used in high-voltage industrial I/O modules where latching is handled externally | Choose ADG1434BRUZ only if lower on-resistance and higher voltage rating outweigh loss of integrated address control |
Compared with MAX4532EAP+, the MAX4532CAP+ offers identical electrical performance at lower cost for commercial-temperature applications; versus ADG1434BRUZ, it trades higher RON for built-in address decoding and fault-safe enable logic - reducing external component count in embedded control designs.

FAQ
What is the maximum supply voltage rating for MAX4532CAP+?
The MAX4532CAP+ has an absolute maximum V+ rating of +13V relative to V−, with recommended dual-supply operation from ±2V to ±6V or single-supply operation from +2V to +12V. Exceeding ±6V or +12V risks permanent damage, and operation above +13V differential violates Absolute Maximum Ratings.
Does MAX4532CAP+ support true bidirectional signal flow?
Yes, MAX4532CAP+ supports fully bidirectional analog signal flow: NO, NC, and COM pins are electrically identical and interchangeable. Signals pass with equal integrity in either direction, confirmed by datasheet specification "NO_, NC_, and COM_ pins are identical and interchangeable" and rail-to-rail handling across full V+ to V− range.
How does the dual-enable logic (EN1/EN2) improve system reliability in MAX4532CAP+?
The MAX4532CAP+ requires complementary assertion of EN1 (low) and EN2 (high) to activate switches - preventing accidental channel closure during power-up, reset, or noise events. This fault-mitigation design ensures all switches remain open unless both enables meet valid logic states, a key requirement in avionics and medical safety systems.
Can MAX4532CAP+ operate from a +3V single supply?
Yes, MAX4532CAP+ operates from +3V single supply (V− = GND), with verified RON = 600Ω max and tTRANS = 350ns typical per datasheet Electrical Characteristics-Single +3V Supply table. Performance degrades gradually below +3V, but functional operation is maintained down to ~+1.7V at room temperature.
Is the MAX4532CAP+ pin-compatible with the 74HC4353?
Yes, MAX4532CAP+ is explicitly stated as pin-compatible with the 74HC4353 in the General Description. Both share identical 20-pin SO/SSOP/DIP pinouts, functionally matching EN1/EN2, ADDA/ADDB/ADDC, LE, COM/NO/NC assignments - enabling drop-in replacement where enhanced analog performance (lower RON, rail-to-rail, ESD) is needed.
