Analog Devices Inc./Maxim Integrated MAX4052CSE+T

Overview

MAX4052CSE+T 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, guarantees 100Ω on-resistance at ±5V, and exhibits only 0.1nA off-leakage at +25°C - enabling precision signal selection in battery-powered data-acquisition front-ends.

For engineers reviewing the MAX4052CSE+T datasheet, MAX4052CSE+T pinout, MAX4052CSE+T application, or MAX4052CSE+T equivalent, key selection criteria include guaranteed channel-to-channel on-resistance match (12Ω), break-before-make timing (≤200ns), low crosstalk (<–90dB), high off-isolation (<–90dB), and compatibility with TTL/CMOS logic levels across supply configurations.

Technical Context

The MAX4052CSE+T implements two independent 4:1 analog multiplexers using complementary CMOS switch architecture, with separate address inputs (ADDA, ADDB) and shared inhibit (INH) control. Each multiplexer routes one of four NOx inputs to its COM terminal based on binary address decoding, with no internal latching or buffering - preserving signal integrity for DC-coupled and audio-frequency applications.

Its analog path operates without ground reference: signals swing rail-to-rail between V+ and V−, while digital control logic runs from V+ and GND. Internal ESD diodes clamp NO/COM pins to V+/V−, requiring careful power sequencing (V+ before V− before signals) to avoid unintended conduction during startup or fault conditions.

FAQ

What is the maximum analog signal voltage range supported by the MAX4052CSE+T?

The MAX4052CSE+T supports rail-to-rail analog signals between V− and V+. With ±5V supplies, this means –5V to +5V; with +5V single supply (V− = GND), it supports 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V− down to –17V, but analog signal swing remains bounded by the actual supply rails applied to V+ and V−.

Can the MAX4052CSE+T operate from a +3.3V single supply?

Yes, the MAX4052CSE+T is fully specified for single-supply operation from +2.7V to +16V. At +3.3V, typical on-resistance increases to ~250Ω (vs. 100Ω at ±5V), and switching times lengthen, but all logic thresholds, leakage specs, and functionality remain valid per the datasheet's +3V supply characterization tables.

Does the MAX4052CSE+T require external pull-up or pull-down resistors on its address pins?

No. The MAX4052CSE+T features TTL/CMOS-compatible logic thresholds (0.8V to 2.4V) and low input current (±1µA), allowing direct connection to microcontroller GPIOs or FPGA outputs without external biasing. Pull-ups/pull-downs are only needed if the driving source is open-drain or has undefined states during reset.

How does the INH pin function in the MAX4052CSE+T?

The INH (inhibit) pin is an active-high digital control that disables both multiplexers simultaneously when driven high. When INH = high, all internal switches open regardless of ADDA/ADDB state - providing hardware-level channel isolation for safety-critical or power-saving modes. When INH = low, normal address-controlled switching resumes.

Is the MAX4052CSE+T pin-compatible with the 74HC4052?

Yes, the MAX4052CSE+T is explicitly designed as a pin-compatible, functionally enhanced replacement for the 74HC4052. It shares identical pinout, logic-level compatibility, and dual 4:1 mux topology, while improving on-resistance (100Ω vs. ~120Ω), leakage (0.1nA vs. ~100nA), and supply flexibility (±2.7V to ±8V vs. ±2V to ±6V).
