Analog Devices Inc./Maxim Integrated MAX4664CPE

Overview

MAX4664CPE from Maxim Integrated is a quad SPST analog switch with four normally closed (NC) channels, 5Ω max on-resistance, 0.5Ω max R_ON match between channels, and rail-to-rail signal handling up to ±20V dual supply or +36V single supply. It delivers low distortion in automatic test equipment and reed relay replacement applications where precise analog switching and leakage-limited performance are critical.

For engineers reviewing the MAX4664CPE datasheet, MAX4664CPE pinout, MAX4664CPE application, or MAX4664CPE equivalent, key selection criteria include guaranteed break-before-make timing (not applicable to MAX4664), NC-only topology, ±4.5V to ±20V dual-supply compatibility, TTL/CMOS logic thresholds, and 5nA max off-leakage at +85°C - all validated for industrial-grade reliability in signal routing and instrumentation designs.

Technical Context

The MAX4664CPE implements a CMOS-based quad SPST architecture with independent digital control inputs driving four normally closed analog paths. Each channel features matched on-resistance (≤0.5Ω variation) and flat on-resistance (≤0.5Ω variation over ±10V signal range), enabling precision multiplexing without gain error across channels.

It operates from either single +4.5V to +36V or dual ±4.5V to ±20V supplies, with logic inputs referenced to VL (typically +5V) and compatible with TTL/CMOS thresholds (+0.8V low, +2.4V high). Internal ESD protection exceeds 2kV per Method 3015.7, and off-isolation reaches –62dB at 1MHz.

Key Specifications

Pinout & Package

MAX4664CPE is housed in a 16-pin plastic DIP package (0.3-inch width), suitable for through-hole prototyping and industrial PCBs requiring mechanical stability and thermal margin. Pin numbering follows standard DIP convention with notch-left orientation.

FAQ

What is the default switch state of MAX4664CPE?

The MAX4664CPE features four normally closed (NC) analog switches - meaning each COM-to-NC path conducts when its corresponding IN pin is at logic low (≤0.8V). This fail-safe behavior ensures continuity during power loss or controller reset, making MAX4664CPE ideal for safety-critical signal paths in test equipment and telecom line cards.

Does MAX4664CPE support single-supply operation?

Yes, MAX4664CPE supports single-supply operation from +4.5V to +36V. In this mode, connect V− to GND, apply the positive supply to V+, and use VL = +5V for logic interface. The device maintains rail-to-rail analog signal handling from GND to V+, with full specification compliance including 5Ω max R_ON and 5nA max off-leakage at +85°C.

What is the maximum signal voltage range supported by MAX4664CPE?

MAX4664CPE supports analog signals from V− to V+, enabling true rail-to-rail operation. With dual ±15V supplies, it handles ±15V signals; with single +12V supply, it passes 0V to +12V. Absolute maximum ratings allow V+ to V− differential up to 44V, but specified performance is guaranteed only within ±20V dual or +36V single supply limits.

How does MAX4664CPE compare to MAX4666 in terms of switching behavior?

Unlike the MAX4666 (which integrates two NC and two NO switches with guaranteed break-before-make timing), the MAX4664CPE contains four NC-only switches with no break-before-make assurance. This makes MAX4664CPE unsuitable for applications requiring guaranteed isolation during state transitions, such as analog muxes feeding shared ADC inputs - where MAX4666 would be preferred.

Is heat dissipation a concern for MAX4664CPE in continuous operation?

At TA = +70°C, MAX4664CPE in plastic DIP has a derated power dissipation limit of 842mW. With typical R_ON = 5Ω and 10mA channel current, power per switch is just 0.5mW - well below thermal limits. Even under worst-case 100mA continuous current, total dissipation remains ≤50mW, allowing safe operation without heatsinking in most industrial environments.
