Product details
Overview
The MAX4530CAP+T from Maxim Integrated is an 8-channel CMOS analog multiplexer with dual complementary enable inputs (EN1/EN2), address latching (LE), and three address lines (ADDA/ADDB/ADDC). It operates from single +2V to +12V or dual ±2V to ±6V supplies, delivers rail-to-rail signal handling, exhibits ≤150Ω on-resistance at +5V, and supports <1µW quiescent power - ideal for low-power data acquisition and battery-operated test equipment.
For engineers reviewing the MAX4530CAP+T datasheet, MAX4530CAP+T pinout, MAX4530CAP+T application, or MAX4530CAP+T equivalent, key selection criteria include its 20-pin SSOP package, ±4.5V switching performance (tON = 150ns, tOFF = 120ns), 1nA COM-off leakage at +25°C, 75Ω on-resistance with ±5V supplies, and pin compatibility with 74HC4351.
Technical Context
The MAX4530CAP+T implements a CMOS transmission-gate architecture with independently controlled enable logic and address-latched channel selection. Its dual enable inputs allow hierarchical control of switch banks, while address latching decouples channel selection timing from digital input transitions - critical for glitch-free analog routing in synchronous systems.
All NOx/COM pins are bidirectional and electrically interchangeable; internal ESD protection diodes clamp signals exceeding V+ or V−, enabling robust rail-to-rail operation. Logic thresholds (0.8V/2.4V) ensure TTL- and CMOS-compatibility across supply voltages up to +12V, with leakage currents fully characterized from −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single or ±2V to ±6V dual - supports legacy ±5V and modern low-voltage battery rails |
| On-Resistance (RON) | 75Ω max at ±5V, 150Ω max at +5V - ensures minimal signal attenuation in precision sensor interfaces |
| On-Resistance Matching (∆RON) | 8Ω max between channels - enables matched gain paths in multi-channel instrumentation |
| Switching Speed | tON = 150ns, tOFF = 120ns at ±4.5V - suitable for multiplexed ADC sampling up to ~3MHz |
| Off-Leakage Current | 1nA at TA = +25°C, 50nA at TA = +85°C - preserves accuracy in high-impedance pH or thermocouple front-ends |
| Rail-to-Rail Signal Range | VCOM/VNO = 0V to V+ (single) or −|V−| to +|V+| (dual) - passes full-scale audio, sensor, and control signals without clipping |
| ESD Protection | >2kV per Method 3015.7 - withstands handling and board-level transients in industrial environments |
Pinout & Package
MAX4530CAP+T is housed in a 20-pin SSOP (Shrink Small Outline Package) with 0.65mm pitch, 7.2mm × 5.3mm body, and exposed thermal pad (not electrically connected). Pin 1 is located at the top-left corner adjacent to the index mark.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Drives analog switches and internal logic; must be ≥2V above V− for valid operation |
| V− | Negative supply input | Connect to GND for single-supply use; sets lower analog signal limit in dual-supply mode |
| GND | Digital ground reference | Reference for logic inputs only; isolated from analog signal path and supply return |
| COM | Common analog terminal | Bidirectional node shared across all 8 channels; connects to system reference or signal source |
| NO0–NO7 | Normally-open analog terminals | Eight independent switch outputs; each connects to COM when selected via ADDA/ADDB/ADDC |
| ADDA/ADDB/ADDC | Binary address inputs | 3-bit latchable address (000–111) selects one of eight NOx paths to COM; latched on LE high |
| EN1/EN2 | Complementary enable inputs | Both must be active (EN1=low, EN2=high) to enable switching; provides hardware gating |
| LE | Address latch enable | Edge-triggered latch captures ADDA/ADDB/ADDC state; decouples address hold time from bus timing |
| N.C. | No-connect pins | Pins 3 and 14 are unconnected internally - must be left floating or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® signal handling | Supports analog signals spanning full V− to V+ range - eliminates level-shifting in ±5V or +3.3V systems |
| Break-before-make switching | Guaranteed 4ns minimum interval prevents momentary short-circuits during channel transitions |
| Charge injection ≤1.5pC | Minimizes voltage step errors in sample-and-hold circuits and high-resolution ADC front-ends |
| Logic-compatible thresholds | 0.8V/2.4V thresholds work with 3.3V or 5V microcontrollers without level translators |
| Low dynamic power | <1µW quiescent consumption - extends battery life in portable DMMs and handheld analyzers |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG708BRUZ | 8-channel, 3.3V/5V-only supply; 4Ω RON matching; no dual-enable or address latch | Lacks hierarchical enable control and latched addressing - requires continuous address bus hold | Prefer for compact 3.3V systems where latch-free timing simplifies FPGA interface |
| TS5A3159DCKR | Single 8:1 mux; 5V max supply; 0.75Ω typical RON; no address latching or dual enable | Higher on-resistance flatness but no EN1/EN2 gating - less suitable for fault-tolerant routing | Choose for cost-sensitive consumer audio where ultra-low RON outweighs control flexibility |
Compared with ADG708BRUZ and TS5A3159DCKR, the MAX4530CAP+T uniquely combines address latching, dual complementary enables, and wide supply range (±2V to ±6V or +2V to +12V), making it the only option supporting both legacy ±5V avionics and modern low-voltage portable designs without redesign.

FAQ
What is the operating temperature range for the MAX4530CAP+T?
The MAX4530CAP+T is specified for 0°C to +70°C ambient operation. This commercial-grade temperature range aligns with its CAP suffix designation and suits indoor instrumentation, benchtop test gear, and non-automotive portable electronics where environmental extremes are controlled. The device's leakage and on-resistance parameters are guaranteed across this full range.
Does the MAX4530CAP+T support single-supply operation?
Yes, the MAX4530CAP+T supports single-supply operation from +2V to +12V. To configure for single supply, connect V− to GND. All analog signals then swing from 0V to V+, and logic thresholds remain compatible with standard 3.3V or 5V controllers. Performance metrics like on-resistance and switching speed are specified under both single- and dual-supply conditions.
How does the address latching (LE) function in the MAX4530CAP+T?
The LE (Latch Enable) input captures the state of ADDA, ADDB, and ADDC on its rising edge and holds the selected channel until the next LE transition. This decouples channel selection timing from address bus stability, eliminating setup/hold timing constraints on microcontroller GPIOs. Once latched, the selected NOx–COM path remains active regardless of subsequent address changes.
What is the significance of the dual enable inputs (EN1 and EN2) on the MAX4530CAP+T?
EN1 and EN2 operate as complementary enables: the internal switch matrix activates only when EN1 = low and EN2 = high. This design prevents accidental channel activation during power-up or reset, supports hardware-level gating of entire mux banks, and enables fault-tolerant architectures where independent control signals verify system health before enabling signal paths.
Is the MAX4530CAP+T pin-compatible with the 74HC4351?
Yes, the MAX4530CAP+T is explicitly designed as a pin-compatible replacement for the 74HC4351. Both devices share identical 20-pin SO/SSOP/DIP footprints, matching pin functions (including COM, NO0–NO7, ADDA–ADDC, EN1/EN2, LE, V+, V−, GND), and logic-level thresholds. This allows direct drop-in upgrades to achieve lower on-resistance, rail-to-rail operation, and improved leakage performance.
