Product details

Overview

MAX4666CSE from Maxim Integrated is a quad SPST analog switch IC with two normally closed (NC) and two normally open (NO) channels, guaranteeing break-before-make switching, 5Ω max on-resistance, ±15V dual-supply or +12V single-supply operation, and rail-to-rail analog signal handling - ideal for precision audio routing and automated test equipment signal path control.

For engineers reviewing the MAX4666CSE datasheet, MAX4666CSE pinout, MAX4666CSE application, or MAX4666CSE equivalent, key selection criteria include guaranteed break-before-make timing (10–125 ns), channel-to-channel R_ON match ≤0.5Ω, off-leakage ≤0.5nA at +85°C, and SOIC-16 package compatibility with high-density PCB layouts.

Technical Context

The MAX4666CSE implements CMOS-based transmission-gate architecture with independent logic-controlled IN1–IN4 inputs driving four SPST switches. Its internal structure enforces strict break-before-make timing between complementary NO/NC pairs (Switches 1&4, 2&3), preventing momentary short-circuits during state transitions.

It supports dual ±4.5V to ±20V or single +4.5V to +36V analog supplies, while VL accepts +5V logic supply. TTL/CMOS-compatible input thresholds (+0.8V low, +2.4V high) ensure robust interfacing with microcontrollers and FPGAs across supply configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
On-Resistance (R_ON)	5Ω max - ensures minimal voltage drop and signal attenuation in precision analog paths up to ±10V signal swing.
R_ON Match	0.5Ω max - enables matched gain/attenuation across channels in differential or multi-path signal routing.
Break-Before-Make Delay	10–125 ns - guarantees no overlap between NC and NO conduction, critical for avoiding power-rail shorts in mixed-signal systems.
Off-Leakage Current	0.5 nA max at +85°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits.
Supply Range	+4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and test equipment rails without level-shifting.
Logic Compatibility	TTL/CMOS thresholds (+0.8V / +2.4V) - direct interface with 3.3V/5V controllers without external buffers.
Crosstalk	−60 dB at 1 MHz - suppresses inter-channel interference in multi-signal routing like PBX line switching.

Pinout & Package

MAX4666CSE is housed in a 16-pin narrow SOIC (SOICN) package, 3.9mm width, 1.75mm height, 1.27mm pitch, RoHS-compliant, with standard JEDEC MS-012AC footprint.

Pin/Terminal	Circuit Role	Design Meaning
1, 8, 9, 16	IN1–IN4	Digital control inputs; active-high logic drives corresponding switch state (NO/NC).
2, 7, 10, 15	COM1–COM4	Analog common terminals; carry bidirectional rail-to-rail signals up to ±10V.
3, 6	NO1, NO4	Normally open analog outputs; connect to COM only when respective IN = high.
11, 14	NC2, NC3	Normally closed analog outputs; disconnect from COM only when respective IN = high.
4	V−	Negative analog supply; tied to GND for single-supply operation.
5	GND	Digital/analog reference ground; requires low-impedance connection to minimize noise coupling.
12	VL	Logic supply input; must be +5V for specified input thresholds and timing.
13	V+	Positive analog supply; sets upper rail for analog signal range and R_ON performance.

Key Features

Feature	Design Value
Guaranteed break-before-make	Enforces safe switching sequence between NO and NC paths, eliminating transient short-circuits in power-sensitive analog nodes.
Rail-to-rail signal handling	Supports full-swing analog signals from V− to V+, enabling use with ±15V op-amps or 0–10V industrial sensors without clipping.
0.5Ω R_ON matching	Ensures consistent gain/phase response across parallel signal paths in instrumentation multiplexers or balanced audio switches.
ESD protection >2kV	Meets MIL-STD-883 Method 3015.7 - reduces handling damage risk during assembly and field maintenance.
Low charge injection (25pC)	Minimizes voltage glitches in sample-and-hold or ADC front-end applications where signal settling time is critical.

FAQ

What is the guaranteed break-before-make timing specification for MAX4666CSE?

The MAX4666CSE guarantees a break-before-make time delay of 10 ns minimum to 125 ns maximum under single-supply conditions (V+ = +12V, V− = GND), measured from 50% of the falling edge on one switch to 50% of the rising edge on its complementary switch. This parameter is explicitly tested and specified in the Electrical Characteristics table for the MAX4666 variant, distinguishing it from the MAX4664/MAX4665.

Can MAX4666CSE operate from a single +5V supply?

No - the MAX4666CSE requires a minimum analog supply of +4.5V, and its specified performance (including R_ON, leakage, and timing) is validated only at V+ ≥ +5V. At +5V, R_ON rises to 8Ω max (vs. 5Ω at +12V), and logic thresholds remain fixed at +0.8V/+2.4V, necessitating compatible 5V logic drivers. Operation below +4.5V is outside absolute maximum ratings.

Does MAX4666CSE support rail-to-rail operation with V− tied to GND?

Yes - when V− is connected to GND (single-supply mode), the MAX4666CSE supports rail-to-rail analog signals from 0V to V+. For example, with V+ = +12V and V− = GND, COM/NO/NC terminals handle 0V to +12V signals without clipping or increased distortion, as confirmed by the Input Voltage Range specification and Typical Operating Characteristics plots.

What is the maximum continuous current per switch in MAX4666CSE?

The MAX4666CSE supports ±100mA continuous current through each COM, NO, or NC terminal, as stated in the Absolute Maximum Ratings table. Exceeding this risks thermal overstress or parametric shift; peak pulsed current is limited to ±300mA at 1ms/10% duty cycle. Derating applies above +70°C ambient per the 8.70mW/°C SOIC power dissipation curve.

Is the MAX4666CSE pin-compatible with other variants in the MAX466x family?

Yes - MAX4664CSE, MAX4665CSE, and MAX4666CSE share identical 16-pin narrow SOIC pinouts and package dimensions. However, their internal switch configurations differ: MAX4664 is 4×NC, MAX4665 is 4×NO, and MAX4666 is 2×NO + 2×NC with break-before-make. Swapping requires firmware and schematic verification due to logic polarity and functional differences.
