Product details
Overview
MAX314LEPE from Maxim Integrated is a quad SPST analog switch with two normally closed (NC) and two normally open (NO) channels, designed for precision signal routing in industrial and test equipment. It features 10Ω max on-resistance, 1.5Ω max RON matching between channels, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling up to ±15V. Its +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V) enable direct interface with low-voltage microcontrollers in mixed-supply systems.
For engineers reviewing the MAX314LEPE datasheet, MAX314LEPE pinout, MAX314LEPE application, or MAX314LEPE equivalent, this page delivers verified electrical specs, thermal-rated package details (16-pin Plastic DIP, –40°C to +85°C), channel configuration logic, leakage performance at temperature, and real-world timing behavior under dual- and single-supply conditions.
Technical Context
The MAX314LEPE implements four independent CMOS SPST switches in a single die, with dedicated NC and NO terminals per channel-switches 1 and 4 are NC, while switches 2 and 3 are NO. Its architecture guarantees break-before-make timing (1–10 ns) only for internal channel pairs 1/4 and 2/3, preventing momentary shorting during state transitions.
It operates across dual supplies (±4.5V to ±20V) or single supply (+4.5V to +36V), supporting rail-to-rail analog signals from V– to V+. Input logic thresholds remain stable over supply voltage (VIH/VIL fixed at 2.0V/0.8V), and on-resistance flatness is guaranteed ≤4Ω over the full signal range, ensuring minimal THD in audio routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 10Ω max - ensures <0.1% gain error in 1kΩ impedance paths and low insertion loss in signal chains. |
| RON Matching (ΔRON) | 1.5Ω max - enables precise matched-channel applications like differential signal switching or relay replacement. |
| Analog Signal Range | ±15V (dual) or 0 to +12V (single) - supports industrial sensor interfaces and audio line-level routing without level shifting. |
| Off-Leakage Current | ±2.5nA at +85°C - preserves accuracy in high-impedance sample-and-hold or sensor multiplexing circuits. |
| Turn-On/Off Time | 275ns / 235ns max (dual supply) - suitable for data-acquisition sampling rates up to ~1.5 MSPS with deterministic timing. |
| Crosstalk | –96dB at 20kHz - prevents audible interference in multi-channel audio routing or adjacent-channel measurement systems. |
| Logic Compatibility | +3V logic (VIH = 2.0V, VIL = 0.8V) - interoperable with 3.3V FPGAs, microcontrollers, and CPLDs without level shifters. |
Pinout & Package
MAX314LEPE is housed in a 16-pin Plastic DIP package (P16-2), rated for –40°C to +85°C operation, with through-hole mounting and standard 0.3" wide body. Pin 12 is no-connect (N.C.), and exposed-pad variants are not applicable to this DIP version.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2, IN3, IN4 | Logic Control Inputs | Digital inputs controlling respective switch states; active-high, +3V compatible, <0.5µA input current. |
| COM1–COM4 | Analog Common Terminals | Signal path center points; bidirectional conduction with matched RON and low charge injection (<30pC). |
| NC1, NC2, NC3, NC4 | Normally Closed Analog Terminals | Connected to COMx when INx = LOW (only pins 3,6,11,14 used; NC1/NC4 on switches 1/4). |
| NO1, NO2, NO3, NO4 | Normally Open Analog Terminals | Connected to COMx when INx = HIGH (only pins 3,6,11,14 used; NO1/NO4 on switches 1/4 - but MAX314LEPE uses pins 3 & 6 as NO1/NO4, pins 11 & 14 as NC3/NC2). |
| V+, V– | Analog Supply Rails | Support dual ±4.5V to ±20V or single +4.5V to +36V; V– tied to GND for single-supply mode. |
| GND | Ground Reference | Logic and substrate reference; separate from analog return paths in mixed-signal layouts. |
Key Features
| Feature | Design Value |
|---|---|
| Break-Before-Make Timing | Guaranteed 1–10 ns delay between switch opening and closing - eliminates signal shorting in reconfigurable filter or gain-setting networks. |
| Rail-to-Rail Signal Handling | Full conduction from V– to V+ - enables direct interfacing with ±10V industrial sensors or op-amp outputs without clamping diodes. |
| Low Charge Injection | ±30pC max - minimizes voltage glitch in sample-and-hold circuits and preserves ADC accuracy during multiplexing. |
| Supply-Sequence Independence | No VL pin required - eliminates power-up sequencing constraints present in legacy MAX312/MAX313, simplifying system power design. |
| High Off-Isolation | –75dB at 1MHz - suppresses crosstalk in dense PCB layouts and maintains signal integrity in multi-channel test instrumentation. |
Applications
| Test Equipment Signal Routing | Industrial Data-Acquisition Multiplexing |
|---|---|
Use Scenario: Automated test systems route multiple sensor inputs to a shared ADC or oscilloscope front-end using programmable analog switching. IC Role / Device Role / Timing Role: Quad SPST switch providing isolated, low-distortion signal paths with matched on-resistance for calibrated measurements. Use Value: 1.5Ω RON matching ensures consistent gain across channels; ±2.5nA leakage at +85°C prevents drift in high-impedance thermocouple or strain-gauge inputs. |
Use Scenario: PLC or RTU modules condition and select among dozens of analog field inputs before digitization. IC Role / Device Role / Timing Role: Two NC + two NO topology allows simultaneous fault-safe bypass (NC) and active signal selection (NO) in redundant I/O architectures. Use Value: Dual-supply operation (±15V) accommodates legacy 4–20mA transmitters and ±10V sensor outputs without external level translation. |
| Audio Line-Level Switching | Avionics Signal Management |
Use Scenario: Professional audio mixers or broadcast gear dynamically route line-level signals between processing stages or output buses. IC Role / Device Role / Timing Role: Low-THD analog switch enabling transparent signal pass-through with <–90dB distortion at 1kHz (RL = 100kΩ). Use Value: 10Ω RON and 47pF on-capacitance preserve bandwidth >10MHz; crosstalk <–96dB prevents audible bleed between stereo or multichannel paths. |
Use Scenario: Flight control or navigation subsystems switch between primary and backup sensor feeds (e.g., air data computers, inertial units). IC Role / Device Role / Timing Role: NC/NO hybrid configuration provides fail-safe default path (NC) plus controlled override (NO) for redundancy management. Use Value: –40°C to +85°C rating meets DO-160 environmental requirements; break-before-make timing prevents transient shorts during critical flight-phase transitions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314LESE | Same electrical specs, 16-pin narrow SO package (surface-mount), no through-hole mounting option. | Better suited for space-constrained PCBs; requires reflow assembly instead of wave soldering. | Select MAX314LESE for automated SMT production; MAX314LEPE remains optimal for prototyping, repair, or legacy through-hole designs. |
| ADG444BRUZ | Quad SPST, +3V logic-compatible, but higher RON (45Ω typ), wider temp range (–40°C to +125°C), different pinout (no NC/NO distinction - all NO). | Lacks NC/NO hybrid topology; unsuitable for fail-safe bypass configurations requiring default-closed paths. | Choose ADG444BRUZ only if extended temperature range is mandatory and NC functionality is unnecessary; MAX314LEPE is irreplaceable where NC/NO pairing is required. |
Compared with MAX314LESE, MAX314LEPE offers identical performance in a through-hole DIP package for manual assembly and legacy compatibility; versus ADG444BRUZ, it delivers superior RON, NC/NO flexibility, and lower leakage-but lacks automotive-grade temperature support.

FAQ
What is the maximum supply voltage rating for MAX314LEPE?
The MAX314LEPE supports dual supplies from ±4.5V to ±20V or single supply from +4.5V to +36V. Absolute maximum ratings specify V+ up to +44V and V– down to –44V, but sustained operation beyond ±20V or +36V violates specifications and risks permanent damage. Always observe the recommended operating ranges in the Electrical Characteristics tables.
Does MAX314LEPE support rail-to-rail analog signal switching?
Yes, MAX314LEPE supports rail-to-rail analog signal switching - signals from V– to V+ are passed with low distortion and guaranteed on-resistance. This capability is confirmed in both dual-supply (±15V) and single-supply (+12V) test conditions, enabling direct connection to op-amp outputs and industrial sensor interfaces without external biasing.
How are the NC and NO channels assigned on MAX314LEPE?
On MAX314LEPE, channels 1 and 4 are normally closed (NC), meaning COM1–NC1 and COM4–NC4 conduct when IN1/IN4 = LOW; channels 2 and 3 are normally open (NO), so COM2–NO2 and COM3–NO3 conduct only when IN2/IN3 = HIGH. Pin assignments follow the DIP layout: pins 3 & 6 = NO1 & NO4; pins 11 & 14 = NC3 & NC2.
What is the leakage current performance of MAX314LEPE at +85°C?
At +85°C, MAX314LEPE guarantees off-leakage current of ±2.5nA for both NO/NC terminals and COM terminal (ICOM(OFF)), and ±5nA for COM on-state leakage (ICOM(ON)). These values are 100% tested at hot temperature and correlate to tighter ±0.02nA typical values at +25°C, making it suitable for high-impedance sample-and-hold and precision sensor multiplexing.
Is MAX314LEPE pin-compatible with earlier MAX314 versions?
Yes, MAX314LEPE is pin-compatible with MAX314CPE and MAX314CSE in the same 16-pin DIP/SO packages. The 'L' suffix denotes improved specs (lower leakage, better RON matching, supply-sequence independence), but pin functions, layout, and footprint remain identical - enabling drop-in replacement in existing designs without PCB modification.
