Product details
Overview
MAX4532EAP 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 routing and avionics signal switching.
For engineers reviewing the MAX4532EAP datasheet, MAX4532EAP pinout, MAX4532EAP application, or MAX4532EAP equivalent, key selection criteria include its -40°C to +85°C industrial temperature rating, 20-pin SSOP package, break-before-make timing (10ns typ), <1µW quiescent power, and compatibility with TTL/CMOS logic at +5V supply.
Technical Context
The MAX4532EAP implements three fully independent SPDT switches, each with separate COM, NO, and NC terminals, controlled via shared address latching (ADDA/ADDB/ADDC) and dual enable inputs (EN1/EN2). Its internal CMOS architecture uses V+ and V− to bias analog pass transistors, enabling rail-to-rail operation without level-shifting circuitry.
Switch control employs synchronous address latching via LE input, allowing stable channel selection independent of EN1/EN2 state. All digital inputs meet TTL/CMOS thresholds (0.8V low / 2.4V high) across full supply range, and ESD protection exceeds 2kV per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - supports battery-powered and industrial rail systems without external regulators |
| On-Resistance (RON) | 150Ω max at +5V supply - ensures minimal signal attenuation in audio and sensor paths |
| RON Matching | 8Ω max between channels - critical for matched gain/phase in differential or multi-channel routing |
| Off-Leakage Current | 50nA max at +85°C - preserves DC accuracy in high-impedance sensor front-ends |
| Enable Turn-On Time | 120ns max at ±4.5V - enables fast reconfiguration in ATE and test instrumentation |
| Charge Injection | 1.5pC typ - limits voltage glitch during switching in precision DAC/ADC interfaces |
| Off Isolation | -65dB at 1MHz - suppresses crosstalk between adjacent SPDT sections in mixed-signal boards |
Pinout & Package
MAX4532EAP is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, footprint-compatible with industry-standard 20-pin SO and DIP variants. Thermal performance supports continuous operation at +85°C ambient with standard PCB copper pour.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal switch gates and logic; sets upper analog signal limit (up to V+) |
| V− | Negative analog supply | Drives switch gates in dual-supply mode; connect to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path |
| LE | Address latch enable | Freezes ADDA/ADDB/ADDC state to select active channel; asynchronous to EN1/EN2 |
| EN1, EN2 | Complementary enable inputs | Both must be asserted (EN1=low, EN2=high) to activate any switch; enables power-gating |
| ADDA, ADDB, ADDC | 3-bit binary address inputs | Select one of eight possible SPDT configurations across three switches (e.g., COMA–NOA, COMB–NCB, COMC–NOC) |
| COMA, COMB, COMC | Analog common terminals | Center pins of each SPDT; bidirectional - may serve as input or output |
| NOA–NOC, NCA–NCC | Normally-open / normally-closed switch terminals | Paired with respective COMx; signal routing determined by address + enable state |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output signals from V− to V+, eliminating level-shifter requirements in ±5V or +3.3V systems |
| Break-before-make switching | Guaranteed 4ns min / 10ns typ interval prevents momentary shorting during channel transitions |
| Pin compatibility with 74HC4353 | Direct drop-in replacement for legacy logic-controlled analog switches without PCB redesign |
| Low dynamic power consumption | <1µW typical supply current enables use in always-on battery monitoring and portable medical devices |
| TTL/CMOS logic interface | 0.8V/2.4V thresholds ensure reliable operation with microcontrollers, FPGAs, and ASICs across supply voltages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog SPDT switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4532EWP | Same electrical specs, but in 20-pin SO package (1.27mm pitch) - larger footprint, higher thermal resistance | Suitable for prototyping or legacy SO-based designs; less dense than SSOP for space-constrained layouts | Select when board assembly uses SO carriers or requires easier hand-soldering access |
| ADG1434BRUZ | 4-channel SPDT, 4.7Ω RON typ, ±15V tolerant, but no address latching or EN1/EN2 complementarity | Better for high-voltage industrial I/O; lacks integrated decode logic - requires external FPGA or MCU control | Choose when lower on-resistance or wider supply range is prioritized over integrated addressing |
Compared with MAX4532EWP and ADG1434BRUZ, the MAX4532EAP uniquely combines industrial temperature range, compact SSOP packaging, built-in 3-bit address decoding, and complementary enable architecture - enabling simpler, more robust signal routing in embedded avionics and portable instrumentation.

FAQ
What is the operating temperature range of the MAX4532EAP?
The MAX4532EAP is rated for operation from -40°C to +85°C, making it suitable for industrial and avionics environments where extended thermal stability is required. This rating is confirmed in the Ordering Information table and applies specifically to the E-grade (EAP) variant - distinct from the C-grade (CAP) version limited to 0°C to +70°C.
Does the MAX4532EAP support single-supply operation?
Yes, the MAX4532EAP supports single-supply operation from +2V to +12V by connecting V− to GND. In this configuration, analog signals swing from 0V to V+, and all logic thresholds remain compatible with TTL/CMOS levels. The datasheet confirms functional operation down to +1.7V, though RON and switching times degrade below +2V.
How many independent switches does the MAX4532EAP contain?
The MAX4532EAP contains three fully independent single-pole/double-throw (SPDT) switches - labeled COMA/NOA/NCA, COMB/NOB/NCB, and COMC/NOC/NCC - each with dedicated terminals and jointly controlled via ADDA/ADDB/ADDC and EN1/EN2. This differs from the MAX4530 (8-channel mux) and MAX4531 (dual 4-channel mux).
Is the MAX4532EAP pin-compatible with the 74HC4353?
Yes, the MAX4532EAP is explicitly stated in the General Description to be pin compatible with the 74HC4353. Pin mapping matches functionally: V+, GND, V−, EN1, EN2, LE, ADDA–ADDC, and all COM/NO/NC terminals align directly - enabling drop-in replacement without layout changes.
What is the maximum on-resistance matching between channels in the MAX4532EAP?
The MAX4532EAP guarantees on-resistance matching (∆RON) of 8Ω maximum between any two channels under specified conditions (TA = TMIN to TMAX, V+ = +5V, V− = -5V). This value is measured as RON(max) − RON(min) and ensures consistent gain and phase response across switched paths in precision applications.
