Product details
Overview
The MAX4532CWP+T 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 audio-signal routing and test equipment where channel isolation and low charge injection are critical.
For engineers reviewing the MAX4532CWP+T datasheet, MAX4532CWP+T pinout, MAX4532CWP+T application, or MAX4532CWP+T equivalent, key selection criteria include break-before-make timing (10–20ns), off-isolation (−65dB at 1MHz), leakage current (≤50nA at +85°C), and compatibility with TTL/CMOS logic levels across supply ranges.
Technical Context
The MAX4532CWP+T implements three fully independent SPDT switches, each with separate COM, NO, and NC terminals, controlled by ADDA/ADDB inputs and dual enable inputs (EN1/EN2) with address latching via LE. Its internal CMOS switch architecture uses matched P- and N-channel transistors to achieve rail-to-rail analog conduction and low distortion (THD = 0.025% at 1MHz).
Switching is governed by a truth table with latch-enabled address decoding; EN1 and EN2 operate independently to gate switch activation, enabling selective channel control without affecting others. The device features break-before-make timing (10–20ns typ.) to prevent signal shorting during transitions, and its ESD protection (>2kV per Method 3015.7) ensures robustness in handling-sensitive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rails without level-shifting |
| On-Resistance (RON) | 150Ω max at +5V supply - limits voltage drop and power loss in precision signal paths |
| RON Matching | 8Ω max between channels - ensures consistent gain/attenuation across switched audio or sensor channels |
| Off-Leakage Current | 50nA max at +85°C - preserves DC accuracy in high-impedance sensor front-ends |
| Charge Injection | 1.5pC typ. - minimizes glitch-induced error in sample-and-hold or ADC input stages |
| Off Isolation | −65dB at 1MHz - suppresses crosstalk between active and inactive SPDT paths in multi-channel systems |
| Enable Turn-On Time | 100ns typ. at ±4.5V - enables fast reconfiguration in automated test equipment |
Pinout & Package
MAX4532CWP+T is housed in a 20-pin wide SO (Small Outline) package, 7.5mm body width, with standard 0.050" lead pitch and gull-wing leads. Pin 1 marked by bevelled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switch gates and digital logic; sets upper analog signal limit (VCOM/VNO ≤ V+) |
| V- | Negative supply input | Drives analog switch gates; sets lower analog signal limit (VCOM/VNO ≥ V-); connect to GND for single-supply use |
| GND | Digital ground reference | Reference for logic thresholds and internal level translators; isolated from analog signal paths |
| LE | Address latch enable | Latches ADDA/ADDB state; allows asynchronous address updates without immediate switching |
| EN1, EN2 | Independent switch enables | Gate activation of SPDT groups - EN1 controls Switch A, EN2 controls Switches B/C (per truth table) |
| ADDA, ADDB | Binary address inputs | Select NO or NC path per SPDT: 00→NO, 01→NC, 10/11→open (with EN asserted) |
| COMA, COMB, COMC | Common terminals | Center pins of SPDTs; bidirectional - may serve as input or output depending on system topology |
| NOA/NOB/NOC, NCA/NCB/NCC | Normally-open / Normally-closed terminals | Passive, interchangeable signal paths; no internal pull-up/down - require external bias if needed |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4353 | Direct drop-in replacement for legacy HC logic-controlled analog switches without PCB redesign |
| Rail-to-Rail® signal handling | Supports analog signals spanning full V− to V+ range - eliminates clipping in ±5V or +12V data acquisition front-ends |
| Break-Before-Make switching | Guaranteed 10–20ns interval prevents momentary shorting between NO/NC paths - critical for relay-replacement reliability |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds work across +5V, ±5V, and +3V supplies - simplifies interface with mixed-voltage microcontrollers |
| Low power consumption | <1µW quiescent - extends battery life in portable test gear and avionics monitoring units |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog SPDT switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EWP+ | Same functionality and pinout, but rated for −40°C to +85°C industrial temperature range | Suitable for avionics, automotive, or outdoor instrumentation requiring extended thermal operation | Select MAX4532EWP+ when ambient operating temperature exceeds +70°C or requires MIL-STD-810 compliance |
| ADG1433BRUZ | 3-channel SPDT with 4.7Ω RON (lower), but higher 120pF COM-off capacitance and no address latching | Better for low-RON precision instrumentation; lacks LE/EN flexibility for sequenced switching | Choose ADG1433BRUZ when on-resistance <5Ω is critical and external logic handles sequencing |
Compared with MAX4532EWP+, the MAX4532CWP+T offers identical electrical performance at lower cost for commercial-temperature applications; versus ADG1433BRUZ, it trades lower RON for integrated address latching and tighter leakage control - making it preferable for battery-powered, latch-controlled routing where DC accuracy matters more than ultra-low resistance.

FAQ
What is the maximum supply voltage rating for MAX4532CWP+T?
The MAX4532CWP+T has an absolute maximum V+ rating of +13V and V− rating of −0.3V relative to GND. Operating supply must stay within ±2V to ±6V (dual) or +2V to +12V (single). Exceeding these ranges risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the official datasheet.
Does MAX4532CWP+T support single-supply operation with V− tied to GND?
Yes, MAX4532CWP+T supports single-supply operation: tie V− to GND and apply +2V to +12V to V+. All analog signal voltages must remain within 0V to V+, and logic thresholds scale accordingly. The datasheet confirms functional operation down to +1.7V (not guaranteed), with specified performance from +2V.
How many independent switches does MAX4532CWP+T contain?
MAX4532CWP+T contains three fully independent single-pole/double-throw (SPDT) switches - labeled Switch A (COMA/NOA/NCA), Switch B (COMB/NOB/NCB), and Switch C (COMC/NOC/NCC) - each with dedicated control via ADDA/ADDB and shared EN1/EN2 enables per the truth table.
What is the purpose of the LE (Latch Enable) pin on MAX4532CWP+T?
The LE pin on MAX4532CWP+T latches the states of ADDA and ADDB inputs, freezing switch configuration even if address lines change later. This enables glitch-free switching in noisy environments and allows microcontrollers to update addresses asynchronously without unintended channel changes - a key feature distinguishing it from basic analog switches.
Is MAX4532CWP+T pin-compatible with the 74HC4353?
Yes, MAX4532CWP+T is explicitly designed as a pin-compatible upgrade to the 74HC4353, sharing identical 20-pin SO footprint, pin functions (including EN1/EN2, ADDA/ADDB, LE, COM/NO/NC), and logic-level compatibility - enabling direct replacement without layout modification or firmware changes.
