Product details
Overview
MAX4532CWP 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 avionics data acquisition systems.
For engineers reviewing the MAX4532CWP datasheet, MAX4532CWP pinout, MAX4532CWP application, or MAX4532CWP equivalent, key selection criteria include SPDT channel count, dual/single supply flexibility, sub-20ns break-before-make timing, <1µW quiescent power, and compatibility with 74HC4353 logic-level interfaces in space-constrained industrial test equipment.
Technical Context
The MAX4532CWP 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), supporting latched address decoding via LE. All analog paths are bidirectional and support rail-to-rail voltage swing across the full supply range.
Its internal CMOS switch architecture uses matched P- and N-channel transistors to minimize on-resistance flatness (≤13Ω typ) and charge injection (1.5pC typ), while ESD protection (>2kV per Method 3015.7) and TTL/CMOS-compatible digital inputs (0.8V/2.4V thresholds) ensure robust operation in mixed-signal environments with ±5V or +5V logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Configuration | Three independent SPDT switches (COM/NO/NC per channel) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports legacy ±5V and modern low-voltage systems |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in 50Ω–1kΩ impedance circuits |
| On-Resistance Matching (∆RON) | 8Ω max between channels - critical for matched gain/phase in differential or multi-path routing |
| Off-Leakage Current | 1nA max at TA = +25°C (COM-off) - preserves DC accuracy in high-impedance sensor front-ends |
| Enable Turn-On/Off Time | tON(EN) = 150ns, tOFF(EN) = 120ns at ±4.5V - enables fast channel switching in ATE and real-time control |
| Break-Before-Make Interval | 4ns min at +25°C - prevents momentary shorting during channel transitions in safety-critical routing |
Pinout & Package
MAX4532CWP is housed in a 20-pin SO (Small Outline) package, 7.5mm × 12.8mm body, 1.27mm pitch, JEDEC MS-013 compliant, with exposed pad not present. Pin 1 marked by beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply input | Drives internal switch gates and logic; sets upper analog signal limit (up to V+) |
| V- | Negative analog supply input | Drives internal switch gates; sets lower analog signal limit (down to V-); connect to GND for single supply |
| GND | Digital ground reference | Reference for logic inputs and internal level translators; isolated from analog signal paths |
| LE | Address latch enable | Edge-triggered latch captures ADDA/ADDB/ADDC state; independent of EN1/EN2 for glitch-free addressing |
| EN1, EN2 | Complementary switch-enable inputs | Both must be asserted (EN1=low, EN2=high) to activate selected channel; enables power-gating per switch group |
| ADDA, ADDB, ADDC | 3-bit binary channel address inputs | Select one of eight possible SPDT configurations across three channels (see Truth Table) |
| COMA, COMB, COMC | Analog common terminals (per channel) | Bidirectional signal hub - connects to NO or NC based on address and enable state |
| NOA–NOC, NCA–NCC | Normally-open / normally-closed switch terminals | Full bidirectional analog paths; NO/NC interchangeable in layout; no internal pull-up/down |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V- to V+ without clipping - essential for full-scale audio and sensor interfaces |
| Pin compatibility with 74HC4353 | Direct drop-in replacement for legacy HC logic-controlled analog switches - no PCB redesign required |
| 1.5pC typical charge injection | Minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors) during switching |
| −65dB off-isolation at 1MHz | Suppresses crosstalk between active and inactive channels in dense multi-signal routing applications |
| <1µW quiescent power | Enables always-on signal path control in battery-powered portable test gear and remote sensors |
Applications
| Audio-Signal Routing | Avionics Data Acquisition |

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, −40°C to +85°C extended temperature grade | Required for automotive or outdoor industrial deployments where ambient exceeds +70°C | Select MAX4532EWP when operating beyond commercial temperature range; otherwise MAX4532CWP suffices |
| ADG1414BRUZ | 4-channel SPDT, 1.5Ω RON (lower), but requires ≥±4.5V dual or +8V single supply; no address latching | Higher performance in low-RON precision instrumentation, but needs external decode logic and higher supply voltage | Choose ADG1414BRUZ only if RON <2Ω is mandatory and system can accommodate higher supply and discrete control |
Compared with MAX4532EWP, the MAX4532CWP trades extended temperature operation for lower cost and same pinout; compared with ADG1414BRUZ, it offers integrated address latching and wider supply flexibility at the expense of on-resistance, making it optimal for cost-sensitive, space-constrained, and multi-voltage embedded systems.

FAQ
What is the maximum supply voltage rating for MAX4532CWP?
The MAX4532CWP has an absolute maximum rating of +13V between V+ and V−, with recommended operating range of ±2V to ±6V dual supply or +2V to +12V single supply. Exceeding ±6V or +12V risks permanent damage, and operation above +13V violates Absolute Maximum Ratings regardless of duration.
Does MAX4532CWP support single-supply operation with V− tied to GND?
Yes, MAX4532CWP fully supports single-supply operation: tie V− to GND, apply V+ from +2V to +12V, and use digital inputs referenced to GND. All analog signals swing from 0V to V+, and specifications (e.g., 150Ω RON, 1nA leakage) are guaranteed across this range per the datasheet's Single +5V Supply table.
How many independent switch channels does MAX4532CWP provide?
The MAX4532CWP provides three independent single-pole/double-throw (SPDT) switch channels - COMA/NOA/NCA, COMB/NOB/NCB, and COMC/NOC/NCC - each configurable separately via the 3-bit address bus (ADDA/ADDB/ADDC) and dual enable inputs (EN1/EN2).
Is MAX4532CWP pin-compatible with the 74HC4353?
Yes, MAX4532CWP is explicitly designed as a pin-compatible, functionally enhanced replacement for the 74HC4353. It shares identical pinout, logic thresholds, and enable/address interface behavior, while adding rail-to-rail operation, lower leakage, and improved ESD tolerance - enabling direct substitution without layout changes.
What is the purpose of the LE (Latch Enable) pin on MAX4532CWP?
The LE pin on MAX4532CWP is an edge-triggered address latch that captures the state of ADDA/ADDB/ADDC inputs on its rising edge, freezing the channel selection independently of EN1/EN2. This prevents glitches during address transitions and allows asynchronous enable control - a key feature distinguishing MAX4532CWP from basic analog switches.
