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, 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 - used in precision data acquisition systems requiring low distortion and channel isolation.

For engineers reviewing the MAX4663EPE+ datasheet, MAX4663EPE+ pinout, MAX4663EPE+ application, or MAX4663EPE+ equivalent, key selection criteria include guaranteed break-before-make timing (5–125 ns), R_ON matching ≤0.5Ω, off-isolation of –56 dB at 1 MHz, and TTL/CMOS-compatible logic inputs independent of supply voltage.

Technical Context

The MAX4663EPE+ implements four independent CMOS transmission gates in a single 16-pin plastic DIP package, with dedicated IN/COM/NO/NC terminals per switch and separate VL logic supply for level-shifting compatibility. Its internal architecture ensures monotonic R_ON variation over ±10V signal range and matched channel resistance via laser-trimmed process control.

Break-before-make behavior is hardware-guaranteed through internal timing circuitry that enforces ≥5 ns minimum dead time between NC and NO path disconnection/reconnection, preventing momentary shorting in mixed-configuration routing. All switches support bidirectional analog signals up to rail limits, with leakage currents specified at ≤0.5 nA at +85°C.

Key Specifications

Pinout & Package

MAX4663EPE+ uses a 16-pin plastic DIP (dual in-line package) with 0.3-inch body width and standard 0.1-inch pin pitch. Pin 1 is located at the left end of the top row when viewed with notch up.

FAQ

What is the maximum allowable supply voltage for MAX4663EPE+?

The MAX4663EPE+ supports absolute maximum analog supply ratings of V+ to GND = –0.3V to +44V and V– to GND = +0.3V to –44V. For reliable operation, use within the recommended ranges: +4.5V to +36V single supply or ±4.5V to ±20V dual supply. Exceeding these may cause permanent damage, as confirmed in the Absolute Maximum Ratings table.

Does MAX4663EPE+ require external pull-up resistors on its logic inputs?

No, MAX4663EPE+ does not require external pull-up resistors. Its IN pins accept TTL/CMOS logic levels directly, with guaranteed recognition of VIN_L ≤0.8V and VIN_H ≥2.4V across the full supply range. The separate VL pin allows logic thresholds to be set independently of analog supplies, eliminating need for level-shifting components.

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

Break-before-make timing for MAX4663EPE+ is hardware-guaranteed and tested per Figure 3 in the datasheet, with t_OPEN specified from 5 ns (min) to 125 ns (max) at TA = –40°C to +85°C. This parameter is production-tested and ensured by internal timing circuitry - not dependent on external layout or loading conditions.

Can MAX4663EPE+ operate with V− grounded and only a positive supply?

Yes, MAX4663EPE+ supports true single-supply operation with V− connected to GND and V+ ranging from +4.5V to +36V. In this configuration, analog signals swing from GND to V+, and all electrical characteristics - including R_ON, leakage, and switching times - remain fully specified per the Single-Supply Electrical Characteristics table.

What is the thermal performance of MAX4663EPE+ in plastic DIP package?

In its 16-pin plastic DIP package, MAX4663EPE+ has a thermal resistance θ_JA of 10.53°C/W, enabling 842 mW maximum continuous power dissipation at TA = +70°C (derating 10.53 mW/°C above). This supports operation in industrial enclosures up to +85°C ambient when PCB copper area and airflow meet standard JEDEC guidelines.
