Product details
Overview
MAX4066CEE+TG068 from Maxim Integrated is a quad, single-pole single-throw (SPST), CMOS analog switch designed for low-voltage signal routing in battery-powered and precision audio systems. It operates from +2.0V to +16V, delivers 45Ω on-resistance at 12V, 2Ω channel-to-channel matching (MAX4066A variant), and supports bidirectional analog signals up to V+ with TTL/CMOS-compatible control inputs.
For engineers reviewing the MAX4066CEE+TG068 datasheet, MAX4066CEE+TG068 pinout, MAX4066CEE+TG068 application, or MAX4066CEE+TG068 equivalent, key selection criteria include guaranteed on-resistance flatness (≤6Ω), ultra-low off-leakage (100pA at +25°C), -86dB crosstalk, 0.03% THD, and QSOP-16 packaging for space-constrained PCB layouts.
Technical Context
The MAX4066CEE+TG068 implements four independent bilateral SPST switches using complementary CMOS transistor pairs, enabling rail-to-rail analog signal handling from GND to V+. Its logic interface accepts standard TTL/CMOS voltage thresholds (VINH ≥ 2.4V at V+ = 5V; VINL ≤ 0.8V), eliminating level-shifting requirements in mixed-supply systems.
Switch performance is characterized across supply voltages: on-resistance drops from 170Ω at 3V to 45Ω at 12V, while charge injection remains ≤10pC and turn-on/turn-off times are 25ns/15ns (typ.) at 12V. The device maintains <6Ω on-resistance flatness over its full analog signal range (0V to V+), critical for low-distortion audio and precision data-acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +16V - Enables direct integration into 3.3V, 5V, and 12V systems without external regulators |
| On-Resistance (RON) | 45Ω max at V+ = 12V - Ensures minimal signal attenuation and voltage drop in sensor/ADC front-ends |
| Channel Matching (∆RON) | 2Ω max (MAX4066A) - Guarantees consistent gain/attenuation across multiplexed channels in instrumentation |
| Off-Leakage Current | 100pA max at +25°C - Preserves accuracy in high-impedance sample-and-hold and battery-monitoring circuits |
| Crosstalk | -86dB at 1MHz - Prevents signal coupling between adjacent switched paths in multi-channel audio routing |
| Bandwidth | >100MHz - Supports fast digital signals and wideband analog waveforms without phase distortion |
| Total Harmonic Distortion | 0.03% - Meets fidelity requirements for line-level audio switching and medical sensor interfaces |
Pinout & Package
MAX4066CEE+TG068 is housed in a 16-pin QSOP (Quarter Small Outline Package) with 0.635mm pitch, 3.99mm width, and 4.98mm length - optimized for high-density PCB layouts while maintaining hand-solderability. Pin 1 is marked by a dot; pins 3 and 11 are no-connect (N.C.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 8, 11 | NO1–NO4 | Normally open analog terminals - bidirectional signal paths connected only when corresponding INx is high |
| 2, 4, 9, 10 | COM1–COM4 | Common analog terminals - serve as input/output junctions for each SPST switch |
| 5, 6, 7, 14 | IN1–IN4 | TTL/CMOS logic inputs - directly drive switch state (L = OFF, H = ON) without pull-ups |
| 16 | V+ | Positive supply - powers analog and logic sections; sets maximum analog signal swing (0V to V+) |
| 15 | GND | Ground reference - common return for supply, logic, and analog signals |
| 3, 11 | N.C. | No internal connection - must be left unconnected; not usable as thermal pad or auxiliary terminal |
Key Features
| Feature | Design Value |
|---|---|
| PIN-COMPATIBLE WITH 74HC4066 | Direct drop-in replacement for legacy logic-controlled analog switches - no PCB redesign required |
| GUARANTEED ON-RESISTANCE MATCHING | 2Ω max channel-to-channel variation (MAX4066A) - ensures uniform signal path impedance in multiplexers |
| ULTRA-LOW OFF-LEAKAGE | 100pA max at +25°C - prevents DC error accumulation in high-Z sample-and-hold capacitors |
| RAIL-TO-RAIL SIGNAL HANDLING | V+ to GND analog range - eliminates clipping when switching full-scale sensor outputs or audio signals |
| LOW DISTORTION & HIGH BANDWIDTH | 0.03% THD and >100MHz bandwidth - preserves signal integrity in professional audio and test equipment |
Applications
| Battery-Powered Data Loggers | Professional Audio Signal Routing |

IC Role / Device Role / Timing Role: Low-leakage analog multiplexer ensuring DC accuracy and minimizing patient leakage current per IEC 60601-1. Use Value: 100pA off-leakage meets stringent safety limits; 4Ω RON flatness prevents amplitude distortion across biopotential frequency bands. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4066CSD | Same electrical specs, but in 14-pin narrow SO package - 2 fewer pins, no N.C. terminals | Lacks QSOP's compact footprint; requires layout change for pin 1 orientation and thermal relief | Select when board space allows SO-14 and N.C. pins are unnecessary |
| ADG1414BRUZ | Higher on-resistance (1.8Ω typical at 15V), wider supply (±15V dual or 12V single), SPI interface instead of parallel TTL | Supports bipolar signal routing and daisy-chain configuration - unsuitable for simple GPIO control | Choose only if dual-supply operation or serial configuration is required |
Compared with MAX4066CSD and ADG1414BRUZ, the MAX4066CEE+TG068 uniquely combines QSOP-16 packaging, guaranteed 2Ω channel matching, 100pA leakage, and pure parallel TTL control - making it optimal for space-constrained, low-power, high-precision analog multiplexing where simplicity and consistency are critical.

FAQ
What is the operating temperature range for MAX4066CEE+TG068?
The MAX4066CEE+TG068 is rated for 0°C to +70°C ambient operation, as indicated by the 'C' grade suffix in its ordering code. This commercial-grade specification ensures reliable performance in indoor consumer, industrial control, and office equipment environments where thermal management is moderate. The device's leakage and on-resistance remain within guaranteed limits across this full range, validated per Maxim's production testing protocol.
Does MAX4066CEE+TG068 support rail-to-rail analog signal switching?
Yes, the MAX4066CEE+TG068 supports true rail-to-rail analog signal handling from GND to V+, as confirmed in its Absolute Maximum Ratings and Electrical Characteristics tables. When V+ = 5V, analog signals from 0V to 5V pass through the switch with no clipping or distortion - a key capability enabled by its CMOS architecture and verified at both 25°C and temperature extremes.
Is MAX4066CEE+TG068 pin-compatible with the 74HC4066?
Yes, the MAX4066CEE+TG068 is explicitly designed as a pin-compatible upgrade to the industry-standard 74HC4066, as stated in its Features section. Both devices share identical pin functions in the 14-pin DIP/SO packages; however, the MAX4066CEE+TG068 uses a 16-pin QSOP, so mechanical compatibility requires verifying footprint alignment and N.C. pin mapping (pins 3 and 11) in the target layout.
What is the maximum analog signal bandwidth supported by MAX4066CEE+TG068?
The MAX4066CEE+TG068 delivers >100MHz on-channel bandwidth, measured under standard conditions (0dBm signal, 50Ω source/load, V+ = 5V). This bandwidth enables clean switching of fast digital control signals and wideband analog waveforms - including audio harmonics beyond 20kHz and video sync pulses - without significant amplitude roll-off or phase shift in the passband.
How does the leakage current of MAX4066CEE+TG068 compare between MAX4066 and MAX4066A variants?
The MAX4066CEE+TG068 belongs to the MAX4066A variant family, guaranteeing 100pA max COM off-leakage current at +25°C - a tenfold improvement over the standard MAX4066's 1nA limit. This lower leakage is critical for high-impedance applications like sample-and-hold circuits and battery-voltage monitoring, where even sub-nA currents cause measurable drift over time.
