Product details
Overview
MAX314LCPE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST) analog switch with two normally closed (NC) and two normally open (NO) channels, 10Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and +3V logic-compatible inputs (VIH = 2.0V, VIL = 0.8V). It enables precision signal routing in audio and data-acquisition systems requiring rail-to-rail analog handling and low channel-to-channel RON mismatch.
For engineers reviewing the MAX314LCPE+ datasheet, MAX314LCPE+ pinout, MAX314LCPE+ application, or MAX314LCPE+ equivalent, key selection criteria include guaranteed 1.5Ω RON matching between channels, 2.5nA max off-leakage at +85°C, break-before-make timing (1–10ns), crosstalk >96dB at 20kHz, and compatibility with legacy DG411/DG412/DG413 layouts in 16-pin DIP packages.
Technical Context
The MAX314LCPE+ implements a CMOS-based SPST analog switch architecture with independent control of four channels-two NC and two NO-each supporting bidirectional signal flow and rail-to-rail voltage handling across its full supply range. Its logic interface accepts +3V-compatible TTL/CMOS levels without level-shifting, enabling direct interfacing with microcontrollers and FPGAs.
It guarantees monotonic on-resistance flatness (≤4Ω over signal range) and low charge injection (±30pC), critical for sample-and-hold and precision multiplexing. The device eliminates power-supply sequencing constraints present in earlier MAX312/MAX313 generations, allowing flexible V+/V− ramp-up order without latch-up risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 10Ω max - ensures minimal signal attenuation and gain error in precision analog paths |
| RON match between channels | 1.5Ω max - maintains amplitude consistency across multi-channel routing or differential pairs |
| Analog signal range | ±15V (dual) or 0 to +12V (single) - supports rail-to-rail operation without clipping |
| Off-leakage current | ±2.5nA at +85°C - preserves accuracy in high-impedance sensor or integrator circuits |
| Turn-on/turn-off time | 115–275ns - enables fast switching in test equipment and communication signal routing |
| Crosstalk | >96dB at 20kHz - prevents audible interference in stereo audio routing applications |
| Logic input thresholds | VIH = 2.0V, VIL = 0.8V - ensures reliable interface with 3.3V digital controllers without external biasing |
Pinout & Package
MAX314LCPE+ is housed in a 16-pin plastic DIP package (P16-2), through-hole mountable, with 0.300" wide body and standard 0.1" pin pitch. Pin 12 is no-connect (N.C.), pins 4 and 5 are V− and GND respectively, and pin 13 is V+.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1, IN2, IN3, IN4 | Digital control inputs - active-high logic drives corresponding switch state (NC/NO) |
| 2, 7, 10, 15 | COM1, COM2, COM3, COM4 | Analog common terminals - bidirectional signal path junctions for each channel |
| 3, 6 | NO1, NO4 | Normally open analog terminals - connect to COM only when respective IN is high |
| 11, 14 | NC3, NC2 | Normally closed analog terminals - connect to COM when respective IN is low |
| 4 | V− | Negative analog supply - tied to GND for single-supply operation (+4.5V to +36V) |
| 5 | GND | Ground reference - required return path for logic and analog supplies |
| 12 | N.C. | No internal connection - must remain unconnected per datasheet |
| 13 | V+ | Positive analog supply - sets upper rail for analog signal range and powers internal circuitry |
Key Features
| Feature | Design Value |
|---|---|
| +3V logic-compatible inputs | VIH = 2.0V / VIL = 0.8V - eliminates need for level shifters when interfacing with 3.3V microcontrollers |
| Guaranteed RON flatness | ≤2Ω max over full analog signal range - minimizes harmonic distortion in audio paths |
| Break-before-make timing | 1–10ns (MAX314L-specific) - prevents momentary shorting during channel switching in multiplexer designs |
| Rail-to-rail signal handling | Operates with signals from V− to V+ - supports full dynamic range in ±15V industrial instrumentation |
| Pin compatibility | Drop-in replacement for MAX314, DG413, and industry-standard 16-pin SO/DIP analog switches |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX314LEPE+ | Same functionality and pinout, but rated for -40°C to +85°C industrial temperature range vs. 0°C to +70°C for MAX314LCPE+ | Suitable for extended-temperature environments such as outdoor telecom or automotive under-hood modules | Select MAX314LEPE+ when operating beyond commercial temperature limits; otherwise MAX314LCPE+ suffices for lab/test-bench use. |
| DG413DN+ | Pin-compatible 16-pin DIP quad SPST switch, but higher RON (35Ω typ), no guaranteed RON match, and no break-before-make timing spec | Acceptable for non-critical routing where leakage and matching are less constrained | Choose DG413DN+ only if cost sensitivity outweighs precision requirements; MAX314LCPE+ delivers superior matching and leakage performance. |
Compared with MAX314LEPE+, the MAX314LCPE+ trades extended temperature capability for lower cost in commercial-grade applications; compared with DG413DN+, it provides tighter RON matching, lower leakage, and verified break-before-make behavior-critical for high-fidelity signal integrity.

FAQ
What is the maximum supply voltage rating for MAX314LCPE+?
The MAX314LCPE+ supports dual-supply operation from ±4.5V to ±20V, with absolute maximum ratings of ±44V on V+ and V−. For single-supply use, it operates from +4.5V to +36V, with V− tied to GND. Exceeding ±44V or +44V (V+ to GND) risks permanent damage per the Absolute Maximum Ratings table.
Does MAX314LCPE+ require power-supply sequencing?
No, the MAX314LCPE+ does not require strict power-supply sequencing. Unlike earlier MAX312/MAX313 generations, it eliminates the VL pin and tolerates arbitrary V+/V− ramp-up order without latch-up risk. However, absolute maximum ratings must never be exceeded during power-up or operation.
How many normally open and normally closed switches are in MAX314LCPE+?
The MAX314LCPE+ contains exactly two normally open (NO) switches (pins NO1 and NO4) and two normally closed (NC) switches (pins NC2 and NC3), as confirmed by the pin configuration diagram and truth table in the datasheet. This hybrid configuration supports flexible signal path design in multiplexer and redundancy applications.
Is MAX314LCPE+ pin-compatible with DG413?
Yes, MAX314LCPE+ is explicitly stated as pin-compatible with DG413 in the Features section. Both use identical 16-pin DIP/SO/TSSOP footprints and share matching pin functions-including INx, COMx, NOx/NCx, V+, V−, and GND-enabling drop-in replacement in existing DG413 layouts without PCB modification.
What is the typical on-capacitance of MAX314LCPE+?
The typical on-capacitance (CON) of MAX314LCPE+ is 47pF, measured at 1MHz per Figure 6 in the datasheet. This value directly impacts high-frequency bandwidth and settling time in fast-switching applications, and remains stable across temperature and supply conditions within specification.
