Product details
Overview
MAX313LCUE+TG068 from Maxim Integrated is a quad, single-pole/single-throw (SPST), normally open (NO) analog switch IC designed for precision signal routing in ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply systems. It delivers 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V), enabling direct interface with low-voltage microcontrollers in test equipment and audio signal path switching.
For engineers reviewing the MAX313LCUE+TG068 datasheet, MAX313LCUE+TG068 pinout, MAX313LCUE+TG068 application, or MAX313LCUE+TG068 equivalent, this page provides verified electrical specifications, TSSOP-16 pin mapping, rail-to-rail signal handling capability, crosstalk performance (>96dB at 20kHz), and real-world design context for high-fidelity analog switching in communication and avionics systems.
Technical Context
The MAX313LCUE+TG068 implements four independent NO analog switches using CMOS process technology, supporting bidirectional signal conduction with guaranteed RON flatness ≤2Ω over its full analog signal range. Its logic inputs are compatible with +3V CMOS/TTL levels regardless of supply configuration-enabling seamless integration into mixed-voltage systems without level-shifting circuitry.
It operates across industrial temperature range (–40°C to +85°C), supports rail-to-rail analog signal handling (VCOM, VNO = V– to V+), and features low leakage (±2.5nA at +85°C) and fast switching (tON/tOFF ≤275/235ns under dual-supply conditions), making it suitable for sample-and-hold circuits and xDSL modem front-ends where timing integrity and signal fidelity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures minimal voltage drop and power loss in signal paths carrying up to ±100mA continuous current. |
| RON Matching | 1.5Ω max - guarantees consistent gain and phase response across all four channels in multi-path routing applications. |
| Analog Signal Range | V– to V+ - enables true rail-to-rail operation, preserving full dynamic range of input signals in both dual- and single-supply modes. |
| Crosstalk | >96dB at 20kHz - suppresses inter-channel interference in high-density audio or data-acquisition systems. |
| Logic Compatibility | +3V CMOS/TTL (VIH = 2.0V, VIL = 0.8V) - allows direct drive from low-voltage FPGAs, MCUs, and ASICs without external translators. |
| Supply Range | +4.5V to +36V (single) or ±4.5V to ±20V (dual) - supports wide-range industrial, telecom, and avionics power architectures. |
| Off-Leakage Current | ±2.5nA at +85°C - maintains signal integrity in high-impedance sensor interfaces and precision measurement circuits. |
Pinout & Package
MAX313LCUE+TG068 is housed in a 16-pin TSSOP package (package code U16-1), with exposed pad (EP) connected to V+ per Maxim's recommended layout. Pin functions are fully defined for the MAX313L variant and validated for this ordering option.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | Digital control inputs for respective SPST NO switches; active-high, +3V logic compatible. |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal ports connected to load or source in closed state. |
| 3, 6, 11, 14 | NO1, NO2, NO3, NO4 | Normally open analog terminals - conduct only when corresponding INx = logic high. |
| 4 | V− | Negative analog supply input; tie to GND for single-supply operation (+4.5V to +36V). |
| 5 | GND | Ground reference for logic and analog sections; must be low-impedance connection. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or thermal requirements. |
| 13 | V+ | Positive analog supply input; powers analog core and drives exposed pad (EP) in TSSOP. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals spanning full V− to V+ range - eliminates clipping in high-dynamic-range audio and instrumentation. |
| +3V logic compatibility | VIH = 2.0V, VIL = 0.8V - enables direct interfacing with 3.3V microcontrollers and FPGAs without level shifters. |
| Guaranteed RON flatness | ≤2Ω over specified signal range - ensures linear gain response and low THD in audio routing applications. |
| Low charge injection | ±30pC max - minimizes voltage glitches in sample-and-hold and multiplexed ADC front-ends. |
| Break-before-make timing (MAX314L only) | Not applicable - MAX313LCUE+TG068 is NO-only; no break-before-make function implemented. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313LESE | Same functionality and pinout, but in 16-pin narrow SO package; higher thermal resistance (696mW vs. 457mW at +70°C). | Preferred for through-hole prototyping or legacy SO-based PCBs; less suitable for space-constrained layouts. | Select MAX313LESE only if SO footprint is required and thermal margin permits. |
| ADG1414BRUZ | Quad SPST NO switch with 1.8Ω typical RON, but requires ≥4.5V logic threshold; not +3V logic compatible. | Better RON performance at cost of added level-shifting for 3.3V controllers; higher supply current (350µA vs. 200µA). | Choose ADG1414BRUZ only when ultra-low RON outweighs logic compatibility and power budget constraints. |
Compared with MAX313LESE and ADG1414BRUZ, MAX313LCUE+TG068 uniquely balances +3V logic compatibility, 10Ω RON guarantee, TSSOP-16 compactness, and industrial temperature rating-making it optimal for new designs prioritizing MCU interoperability and board area efficiency.

FAQ
What is the operating temperature range for MAX313LCUE+TG068?
The MAX313LCUE+TG068 is rated for operation from –40°C to +85°C, meeting industrial-grade reliability requirements. This range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the datasheet, and applies specifically to the 'E' grade suffix used in this part number.
Does MAX313LCUE+TG068 support single-supply operation?
Yes, MAX313LCUE+TG068 supports single-supply operation from +4.5V to +36V. In this mode, connect V− (pin 4) to GND (pin 5), and apply the positive supply to V+ (pin 13). The analog signal range becomes 0V to V+, and all electrical characteristics-including RON and leakage-are specified under these conditions.
Is MAX313LCUE+TG068 pin-compatible with older MAX313 variants?
Yes, MAX313LCUE+TG068 is pin-compatible with MAX313CUE and MAX313EUE in the same TSSOP-16 package. It also maintains mechanical and functional pin compatibility with DG412, including identical IN/COM/NO pin assignments and logic polarity-enabling drop-in replacement in existing designs.
What is the maximum analog signal voltage that can be applied to MAX313LCUE+TG068?
The maximum analog signal voltage for MAX313LCUE+TG068 is limited by the supply rails: signals at COM or NO pins must remain within V− to V+. With ±15V supplies, the allowable range is –15V to +15V; with +12V single supply, it is 0V to +12V. Exceeding these ranges risks forward-biasing internal protection diodes and violating absolute maximum ratings.
How does the on-resistance matching specification impact system performance in MAX313LCUE+TG068?
The 1.5Ω max RON matching specification in MAX313LCUE+TG068 ensures that gain error between channels remains below 0.15% when driving matched loads-critical for multi-channel data acquisition, balanced audio routing, and I/Q signal processing where amplitude consistency directly affects measurement accuracy and signal fidelity.
