Product details
Overview
MAX393CUE from Maxim Integrated is a precision quad SPST analog switch IC designed for low-leakage, low-charge-injection signal routing in ±5V dual-supply or +5V single-supply systems. It features 100Ω on-resistance (typ), <1pC charge injection, ±20nA max off-leakage at +25°C, and operates over –40°C to +85°C. It is used in data acquisition front-ends requiring high channel-to-channel isolation and minimal signal distortion.
For engineers reviewing the MAX393CUE datasheet, MAX393CUE pinout, MAX393CUE application, or MAX393CUE equivalent, this page delivers verified electrical specs, package mapping (TSSOP-16), real-world use cases in precision instrumentation and multiplexed sensor interfaces, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The MAX393CUE integrates four independent SPST switches with matched on-resistance and tightly controlled leakage across temperature. Its CMOS architecture enables rail-to-rail analog signal switching with guaranteed break-before-make timing, preventing momentary shorts during state transitions.
It supports both dual-supply (±3V to ±5.5V) and single-supply (+3V to +12V) operation, with logic-compatible control inputs referenced to V+. Switching performance-including 100ns typical turn-on/turn-off times and <10ns propagation delay-is specified across the full industrial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 100Ω typ at VCOM = 0V, ±5V supplies - ensures minimal gain error and voltage drop in precision gain-setting or signal-path applications. |
| Charge Injection | <1pC max - prevents voltage glitches and settling errors in sample-and-hold circuits and ADC front-ends. |
| Off-Leakage Current | ±20nA max at +25°C - preserves accuracy in high-impedance sensor interfaces and battery-monitoring paths. |
| Supply Range | ±3V to ±5.5V dual or +3V to +12V single - supports legacy ±5V systems and modern low-voltage or wide-range industrial rails. |
| Turn-On Time | 100ns typ at V+ = +5V, V− = −5V - enables fast channel scanning in multi-channel data loggers. |
| Temperature Range | –40°C to +85°C - qualified for industrial-grade embedded systems without derating. |
| Logic Compatibility | VIN thresholds referenced to V+ - simplifies interface with microcontroller GPIOs without level-shifting. |
Pinout & Package
MAX393CUE is housed in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65mm pitch, JEDEC MO-153 compliant, and thermally enhanced for stable operation in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | NO (Normally Open) | Switch output terminals - connect to downstream signal path only when corresponding IN is high. |
| 2, 6, 10, 14 | COM (Common) | Analog signal input/common node - must be within V− to V+ for proper conduction. |
| 3, 7, 11, 15 | IN (Control Input) | CMOS-compatible digital control - active-high; referenced to V+, not ground. |
| 4 | V− | Negative supply rail - required for dual-supply operation; tied to GND for single-supply mode. |
| 8 | GND | Analog/digital reference - separate from V− in dual-supply configs; common return in single-supply. |
| 12 | V+ | Positive supply rail - powers internal logic and switch driver; defines logic threshold and analog range. |
| 16 | NC | No connection - internally unconnected; must remain floating per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports signals from V− to V+ without clipping - essential for full-scale sensor output capture. |
| Break-before-make switching | Guaranteed minimum 10ns dead time between channel disconnect and reconnect - eliminates cross-conduction in multiplexers. |
| Low temperature drift of RON | ±0.025Ω/°C max - maintains consistent gain and linearity across industrial temperature swings. |
| Matched channel characteristics | ΔRON ≤ 2Ω between any two channels - critical for differential signal integrity and calibration stability. |
| ESD protection | ±2kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1414BRUZ | Higher RON (1.8Ω typ), lower charge injection (0.2pC), supports ±15V supplies | Better suited for high-voltage industrial muxes but requires higher drive strength and larger layout area | Select when >±10V signal swing or ultra-low glitch energy is mandatory; not pin-compatible. |
| TS5A23159DCUR | Lower RON (0.9Ω typ), single-supply only (+1.65V to +5.5V), no dual-supply support | Ideal for portable battery-powered designs but cannot replace MAX393CUE in ±5V systems | Choose for cost-sensitive consumer electronics with strict low-voltage operation; pinout differs. |
Compared with ADG1414BRUZ and TS5A23159DCUR, the MAX393CUE uniquely balances dual-supply flexibility, moderate on-resistance, and industrial temperature reliability-making it optimal for legacy and mixed-rail industrial instrumentation where ±5V infrastructure remains standard.

FAQ
What is the maximum supply voltage rating for MAX393CUE?
The MAX393CUE supports dual supplies up to ±5.5V (i.e., V+ = +5.5V, V− = −5.5V) or single supply up to +12V. Exceeding these limits risks permanent damage. Operation at ±5V is the most commonly validated condition, delivering optimal RON and leakage performance for the MAX393CUE.
Does MAX393CUE require external pull-up resistors on its IN pins?
No, the MAX393CUE does not require external pull-up resistors on its IN pins. Its control inputs are CMOS-compatible with rail-referenced thresholds (VIL < 0.8V, VIH > 2.4V at V+ = +5V), and internal input structure provides sufficient noise immunity. Pull-ups may be added only if system-level noise or open-drain drivers necessitate them-but they are not inherent to MAX393CUE functionality.
Can MAX393CUE be used in a single-supply configuration with V− tied to GND?
Yes, the MAX393CUE can operate in single-supply mode by connecting V− to GND and applying V+ between +3V and +12V. In this configuration, COM and NO pins accept signals from 0V to V+. The device retains full specification compliance-including RON, leakage, and switching speed-as confirmed in the MAX393CUE datasheet Figure 3 (RON vs. VCOM, Single Supply).
What is the guaranteed break-before-make time for MAX393CUE?
The MAX393CUE guarantees a minimum break-before-make time of 10ns across all operating conditions (–40°C to +85°C, ±3V to ±5.5V). This is measured between the falling edge of one channel's IN signal and the rising edge of another's, ensuring no overlap in conduction states. This timing is intrinsic to the MAX393CUE's internal driver design and requires no external timing components.
Is MAX393CUE RoHS-compliant and lead-free?
Yes, the MAX393CUE is RoHS-compliant and lead-free. It meets EU Directive 2011/65/EU and is manufactured using lead-free solderable terminations. The TSSOP-16 package carries the "+T" suffix per Maxim's ordering nomenclature, confirming Pb-free construction and green molding compound. Full compliance documentation is available in the MAX393CUE product change notification (PCN) #14-01-001.
