Analog Devices Inc./Maxim Integrated MAX4052CSE+

Overview

MAX4052CSE+ from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports single-supply operation from +2.7V to +16V or dual supplies from ±2.7V to ±8V, delivers rail-to-rail analog switching, and features guaranteed 100Ω on-resistance (±5V), 6Ω channel-to-channel on-resistance match (A-suffix variant), and 0.1nA off-leakage at +25°C - enabling precision signal selection in battery-powered data-acquisition front-ends.

For engineers reviewing the MAX4052CSE+ datasheet, MAX4052CSE+ pinout, MAX4052CSE+ application, or MAX4052CSE+ equivalent, key selection criteria include verified on-resistance flatness (<10Ω), break-before-make timing (30ns typical), off-isolation (<–90dB at 100kHz), crosstalk performance (<–90dB), and compatibility with TTL/CMOS logic levels across supply configurations.

Technical Context

The MAX4052CSE+ implements two independent 4:1 analog multiplexers using matched CMOS transmission gates, each controlled by three address bits (ADDA, ADDB, INH) and sharing V+, V−, and GND supply rails. Its internal logic-level translators isolate digital control signals from analog paths while ensuring TTL/CMOS compatibility across supply voltages.

Each multiplexer section handles rail-to-rail analog signals with no ground reference required; leakage currents are dominated by reverse-biased ESD diodes between NO/COM pins and V+/V−, resulting in sub-nanoampere off-state current at +25°C and <5nA at +85°C for the A-suffix grade.

Key Specifications

Pinout & Package

FAQ

What is the operating temperature range for MAX4052CSE+?

The MAX4052CSE+ is specified for commercial temperature operation from 0°C to +70°C. This rating applies specifically to the C-grade narrow SOIC package variant, and is validated per Maxim's production test flow. The device's leakage, on-resistance, and switching times remain within datasheet limits across this full range, making it suitable for indoor consumer and industrial control applications without extended thermal qualification.

Does MAX4052CSE+ support single-supply operation below 3V?

Yes, MAX4052CSE+ can operate with a single supply as low as +2.7V, though performance degrades below +3V: on-resistance increases significantly (e.g., 700Ω typical at +3V), and switching times lengthen (tON up to 700ns). For reliable operation at 2.7V, verify signal integrity and timing margins in the target application; the datasheet does not guarantee parameters below +3V.

How is the INH pin used in MAX4052CSE+?

The INH (Inhibit) pin on MAX4052CSE+ is an active-high digital control that disables all analog switches when driven high. When INH = V+, both 4:1 multiplexers disconnect all NO–COM paths regardless of ADDA/ADDB state. This provides hardware-level channel blanking for safety-critical sequencing or power-saving modes, and is electrically compatible with 5V TTL/CMOS logic.

Can MAX4052CSE+ handle bipolar analog signals with a single supply?

No - with V− tied to GND in single-supply mode, MAX4052CSE+ only supports unipolar analog signals from 0V to V+. To pass true bipolar signals (e.g., ±2.5V), dual supplies (e.g., V+ = +5V, V− = −5V) must be used. Attempting bipolar signals on a single-supply configuration risks forward-biasing internal ESD diodes and causing excessive leakage or damage.

Is MAX4052CSE+ pin-compatible with the 74HC4052?

Yes, MAX4052CSE+ is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4052. It shares identical pinout, supply pin locations (V+, GND, V−), and digital control interface (ADDA, ADDB, INH), allowing direct replacement without layout changes - while delivering superior analog performance including lower on-resistance, tighter matching, and nanoampere leakage.
