Analog Devices Inc./Maxim Integrated MAX4582CSE+T

Overview

MAX4582CSE+T from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 80Ω on-resistance at ±5V, guarantees ≤1nA off-leakage at +25°C, and achieves < -96dB crosstalk (50Ω) - enabling precision audio/video switching and battery-powered data acquisition.

For engineers reviewing the MAX4582CSE+T datasheet, MAX4582CSE+T pinout, MAX4582CSE+T application, or MAX4582CSE+T equivalent, this page provides verified pin functions, rail-to-rail analog signal handling, AEC-Q100-qualified automotive-grade variants, and real-world selection guidance against functional alternatives with documented on-resistance and leakage differences.

Technical Context

The MAX4582CSE+T implements two independent 4:1 analog multiplexers sharing common address lines (A, B) and an enable input. Each channel handles rail-to-rail analog signals up to VCC–VEE range, with break-before-make switching (4–20ns) preventing signal shorting during channel transitions.

Its CMOS switch architecture uses internal logic-level translators to drive analog gates directly from TTL/CMOS-compatible inputs (0.8V–2.4V thresholds at +5V), while ESD diodes clamp analog pins to VCC/VEE - requiring proper supply sequencing to avoid leakage-induced errors.

Key Specifications

Pinout & Package

MAX4582CSE+T is housed in a 16-pin narrow SO (SOIC-16) package with standard 1.27mm pitch, RoHS-compliant lead-free finish, and thermal pad not exposed (non-TQFN variant).

FAQ

What supply configurations does the MAX4582CSE+T support?

The MAX4582CSE+T operates with ±2V to ±6V dual supplies or a single +2V to +12V supply (with VEE tied to GND). At ±5V, it achieves 80Ω on-resistance and <1nA off-leakage at +25°C. Single-supply operation down to +2V is specified, though on-resistance rises significantly below +3V - always verify RON and leakage curves in the datasheet for your exact VCC/VEE conditions. The MAX4582CSE+T requires no external level shifters for TTL/CMOS logic interfacing.

How does the MAX4582CSE+T handle analog signal directionality?

The MAX4582CSE+T is fully bidirectional: its X0–X3 and Y0–Y3 pins function identically as inputs or outputs depending on signal flow - no internal polarity constraints. Signals pass equally well from X-input to X-output or vice versa, provided they remain within the VEE-to-VCC range. This makes the MAX4582CSE+T ideal for applications like sensor excitation (current out) and measurement (voltage in) on the same pin pair, eliminating need for separate transmit/receive switches.

Is the MAX4582CSE+T pin-compatible with industry-standard analog multiplexers?

Yes - the MAX4582CSE+T is pin-compatible with the 74HC4052 and MAX4052 families, sharing identical SOIC-16 pinouts and truth tables. Address pins A/B, ENABLE, and analog I/O positions match exactly, allowing drop-in replacement in existing designs. However, note that MAX4582CSE+T improves on older parts with lower on-resistance (80Ω vs. 120Ω), tighter RON matching, and reduced leakage - no PCB changes are needed to upgrade.

What is the maximum signal frequency supported by the MAX4582CSE+T?

The MAX4582CSE+T maintains flat on-state response up to 50MHz in 50Ω systems, with <0.02% THD at audio frequencies (20Hz–20kHz). Off-isolation degrades above 10MHz (≈-50dB at 10MHz, worsening ~20dB/decade), so high-frequency blocking relies on layout and external filtering. For video applications, it reliably handles composite NTSC/PAL (≤5MHz) and SVGA (≤40MHz) baseband signals - always validate crosstalk and isolation at your target frequency using the device's S-parameter data.

Does the MAX4582CSE+T require special power sequencing?

Yes - to prevent ESD diode conduction and excessive leakage, power VCC first, then VEE (or GND for single supply), followed by logic inputs and analog signals. Violating this sequence risks current flow through internal clamping diodes, increasing off-leakage and potentially damaging the device. If sequencing isn't feasible, add external series diodes (as shown in Figure 1 of the datasheet), though this reduces usable analog range by ~0.7V. The MAX4582CSE+T draws only 1µA supply current, simplifying power budgeting.
