Analog Devices Inc./Maxim Integrated MAX4663EPE

Overview

MAX4663EPE from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring guaranteed break-before-make switching, 2.5Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - ideal for precision ADC multiplexing and reed-relay replacement in test equipment.

For engineers reviewing the MAX4663EPE datasheet, MAX4663EPE pinout, MAX4663EPE application, or MAX4663EPE equivalent, this page delivers verified electrical specs, terminal roles, real-world use cases in avionics and data acquisition, and validated alternative parts with documented functional and interface differences.

Technical Context

The MAX4663EPE implements CMOS-based transmission-gate architecture with independent logic-level control inputs (IN1–IN4), separate analog supply rails (V+, V−), and dedicated logic supply (VL) ensuring TTL/CMOS compatibility across full voltage ranges. Its internal switch matrix guarantees break-before-make timing of 5ns to 125ns between paired NO/NC channels.

It supports rail-to-rail analog signals up to ±10V with flat on-resistance (≤0.7Ω variation over signal range) and matched channel R_ON (≤0.4Ω max mismatch), enabling low-distortion signal routing in high-fidelity audio and precision instrumentation systems.

Key Specifications

Pinout & Package

MAX4663EPE uses a 16-pin plastic DIP package (0.3-inch width), rated for -40°C to +85°C operation, with through-hole mounting and standard JEDEC MO-016AC footprint.

FAQ

What is the maximum allowable voltage difference between V+ and V− for MAX4663EPE?

The absolute maximum rating specifies V+ to V− must not exceed +44V. This allows safe operation at ±20V dual supplies (40V total), with 4V margin for transient spikes. Exceeding this risks permanent damage to internal protection diodes and oxide layers - always verify supply sequencing per Figure 1 in the datasheet before powering MAX4663EPE in high-voltage applications.

Does MAX4663EPE support true rail-to-rail operation with a +5V single supply?

Yes, MAX4663EPE supports rail-to-rail analog signals from GND to +5V when V− = GND and V+ = +5V. The device maintains 2.5Ω max on-resistance and <0.5Ω R_ON flatness across that full range, enabling accurate switching of baseband signals in low-voltage medical sensors and portable instrumentation without signal clipping.

How is break-before-make timing verified for MAX4663EPE?

Break-before-make timing for MAX4663EPE is production-tested and guaranteed from 5ns to 125ns under all specified conditions (Figure 3). It applies specifically to the paired channels (IN1/IN4 controlling NO1/NC4, and IN2/IN3 controlling NC2/NO3), ensuring no overlap in conduction states during logic transitions - a key differentiator from MAX4661/MAX4662 variants.

Can MAX4663EPE be used with a 3.3V logic supply on the VL pin while running ±15V analog supplies?

Yes, MAX4663EPE accepts VL = 3.3V independently while V+ = +15V and V− = −15V. Its logic inputs remain fully compatible with 3.3V CMOS levels (VIN_H ≥ 2.4V, VIN_L ≤ 0.8V), allowing direct interface with modern low-voltage microcontrollers without level shifters - a feature confirmed in Electrical Characteristics Table "Single Supply" and "Dual Supply" sections.

What is the thermal performance of MAX4663EPE in plastic DIP package at +85°C ambient?

In its 16-pin plastic DIP package, MAX4663EPE has a thermal resistance θ_JA of 10.53°C/W and a maximum continuous power dissipation of 842mW at +70°C, derating linearly above that. At +85°C ambient, usable power drops to ~825mW - sufficient for typical analog switch operation (<10mW per channel), ensuring reliable long-term function in sealed industrial enclosures without forced airflow.
