Product details
Overview
MAX4663CAE+ from Maxim Integrated is a quad SPST analog switch IC with two normally open (NO) and two normally closed (NC) channels, featuring 2.5Ω max on-resistance, guaranteed break-before-make switching, and rail-to-rail signal handling up to ±20V dual supply or +36V single supply. It supports TTL/CMOS logic inputs via dedicated VL pin and delivers matched on-resistance (≤0.5Ω) and flatness (≤0.5Ω) for precision signal routing in data acquisition systems.
For engineers reviewing the MAX4663CAE+ datasheet, MAX4663CAE+ pinout, MAX4663CAE+ application, or MAX4663CAE+ equivalent, key selection criteria include verified break-before-make timing (5–125ns), low charge injection (20pC typ), <0.5nA off-leakage at +85°C, and SSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The MAX4663CAE+ implements CMOS transmission-gate architecture with independent channel control, enabling simultaneous operation of NO and NC pairs without crosstalk-induced coupling. Its break-before-make behavior is electrically guaranteed-not inferred-via internal timing control circuitry that enforces ≥5ns minimum dead time between channel transitions.
It operates across dual supplies (±4.5V to ±20V) or single supply (+4.5V to +36V), with separate VL pin ensuring logic-level compatibility regardless of analog rail voltage. Input voltage range extends from V− −0.3V to V+ +0.3V, and all analog terminals tolerate rail-to-rail signals without degradation in RON flatness or leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 2.5Ω max - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RON Match Between Channels | 0.5Ω max - enables accurate gain/phase matching in multi-channel instrumentation |
| RON Flatness | 0.5Ω max over full signal range - preserves linearity for audio, sensor, and ADC front-end signals |
| Break-Before-Make Time | 5–125ns - prevents momentary shorting during channel switching in multiplexed systems |
| Off-Leakage Current | 0.5nA max at +85°C - maintains signal integrity in high-impedance sample-and-hold circuits |
| Charge Injection | 20pC typ - minimizes voltage glitch on sampled nodes in precision data acquisition |
| Supply Range | +4.5V to +36V single or ±4.5V to ±20V dual - supports industrial, avionics, and test equipment rails |
Pinout & Package
MAX4663CAE+ is housed in a 16-pin SSOP (Shrink Small Outline Package) with 0.65mm lead pitch, 5.0mm × 6.2mm body size, and exposed pad not present. The package supports reflow soldering per JEDEC J-STD-020 and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; handle bidirectional rail-to-rail signals up to ±20V |
| 3, 6 | NC1, NC2 | Normally closed analog terminals; conduct when corresponding IN = 0 |
| 11, 14 | NO3, NO4 | Normally open analog terminals; conduct when corresponding IN = 1 |
| 4 | V− | Negative analog supply; tied to GND for single-supply operation |
| 5 | GND | Logic and substrate reference; separate from analog return path in mixed-signal layout |
| 12 | VL | Dedicated logic supply input; decouples logic threshold from analog rail variations |
| 13 | V+ | Positive analog supply; supports up to +36V for high-voltage signal routing |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1412BRUZ | Quad SPST, 1.8Ω RON, no break-before-make guarantee, requires same supply for logic/analog | Better RON but lacks timing assurance for fault-sensitive multiplexing | Select when lowest on-resistance is primary; avoid where channel shorting must be prevented. |
| TS5A3157DCKR | Single-pole double-throw (SPDT), 0.75Ω RON, 5V-only supply, no dual-rail support | Higher integration per channel but incompatible with ±15V or >5.5V systems | Use only in low-voltage, space-constrained consumer designs-not for industrial or avionics. |
Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX4663CAE+ uniquely combines guaranteed break-before-make timing, dual-supply flexibility, and rail-to-rail operation-making it the only option among the three qualified for reed-relay replacement in safety-critical test and avionics signal paths.

FAQ
What is the guaranteed break-before-make time for MAX4663CAE+?
The MAX4663CAE+ guarantees a break-before-make interval of 5ns minimum to 125ns maximum under all operating conditions, as measured per Figure 3 in the datasheet. This timing is electrically assured-not typical-and applies specifically to the two NO/NC pairs (switches 1&4 and 2&3). The MAX4663CAE+ is the only variant in the MAX466x family with this feature.
Can MAX4663CAE+ operate from a single 5V supply?
Yes, MAX4663CAE+ supports single-supply operation from +4.5V to +36V. At +5V, RON is 4Ω typical (max 5.5Ω), and logic inputs remain compatible via the VL pin-set to +3.3V or +5V. However, rail-to-rail signal swing is limited to 0V to +5V, unlike dual-supply operation which enables ±15V analog ranges.
Does MAX4663CAE+ require external protection diodes for overvoltage?
No-MAX4663CAE+ includes internal ESD protection rated to 2kV HBM, and its absolute maximum ratings allow V+ to GND up to +44V and V− to GND down to -44V. External diodes are optional and only recommended if system-level transients exceed these limits or if power sequencing cannot be controlled.
How does the VL pin affect logic compatibility in MAX4663CAE+?
The VL pin sets the reference for logic thresholds independently of V+ and V−. With VL = +3.3V, VINH = 2.4V and VINL = 0.8V are guaranteed across all analog supply conditions. This eliminates need for level shifters when interfacing with 3.3V microcontrollers while operating from ±15V analog rails.
Is MAX4663CAE+ pin-compatible with other MAX466x variants in SSOP-16?
Yes-MAX4663CAE+, MAX4661CAE+, and MAX4662CAE+ share identical SSOP-16 pinouts and footprint. Function differs only in switch configuration (2NO+2NC vs. 4NC vs. 4NO), so PCBs designed for one can accommodate another with only firmware/control logic changes.
