Product details
Overview
MAX314CPE+ from Maxim Integrated is a quad, single-pole/single-throw (SPST) CMOS analog switch with two normally closed (NC) and two normally open (NO) channels. It features 6.5Ω typical on-resistance, 1.5Ω max on-resistance matching between channels, rail-to-rail signal handling, and operates from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply. It is used in precision audio routing and test equipment where low distortion and tight channel matching are critical.
For engineers reviewing the MAX314CPE+ datasheet, MAX314CPE+ pinout, MAX314CPE+ application, or MAX314CPE+ equivalent, key selection criteria include verified on-resistance flatness (≤2Ω), guaranteed ESD protection (>2000V per Method 3015.7), crosstalk performance (>96dB at 20kHz), and compatibility with DG411/DG412/DG413 pinouts in 16-pin PDIP packages.
Technical Context
The MAX314CPE+ implements a fully complementary CMOS transmission-gate architecture enabling bidirectional conduction and rail-to-rail analog signal switching. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (logic supply), independent of analog supply rails.
Channel configuration is fixed: pins IN1/IN4 control NC1/NC4 (normally closed), while IN2/IN3 control NO2/NO3 (normally open). Break-before-make timing is guaranteed at 70ns (typ) under specified load conditions, preventing momentary shorting during state transitions in mixed-signal routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 6.5Ω typical - ensures minimal voltage drop and signal attenuation in low-level analog paths |
| RON Match | ≤1.5Ω max - enables matched gain/phase response across channels in differential or multi-path systems |
| Analog Signal Range | ±10V (dual supply) or 0V to V+ (single supply) - supports full-rail operation without clipping |
| Crosstalk | >96dB at 20kHz - critical for high-fidelity audio and sensitive measurement signal integrity |
| ESD Protection | >2000V per Method 3015.7 - provides robust handling in benchtop test and industrial environments |
| Turn-On/Off Time | 225ns/185ns (max) - suitable for multiplexed data acquisition up to ~2MHz sampling rates |
| Off-Leakage Current | ±2.5nA at +85°C - preserves accuracy in high-impedance sensor front-ends and sample-and-hold circuits |
Pinout & Package
MAX314CPE+ is housed in a 16-pin plastic DIP (dual in-line package) with 0.300" wide body and standard through-hole mounting. Pin 1 is located at the top-left corner when viewed from the top with the notch or dot oriented upward.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | Logic Input (IN1–IN4) | Controls switch state; IN1/IN4 drive NC1/NC4, IN2/IN3 drive NO2/NO3 |
| 2, 7, 10, 15 | Analog Common (COM1–COM4) | Signal path common node for each SPST channel; bidirectional conduction point |
| 3, 6, 11, 14 | Analog NC Terminals (NC1–NC4) | Normally closed contacts; conduct to COM when IN = 0V |
| - | Analog NO Terminals (NO1–NO4) | MAX314 uses NO2/NO3 only; NO1/NO4 are not connected (NC on die) |
| 4 | V− | Negative analog supply; tie to GND for single-supply operation |
| 5 | GND | Logic ground reference; separate from analog return paths in mixed-signal layouts |
| 12 | VL | Logic supply input; decoupling required for noise immunity with TTL/CMOS drivers |
| 13 | V+ | Positive analog supply; sets upper rail for analog signal range and on-resistance performance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail® Signal Handling | Supports analog signals spanning V− to V+ without degradation - essential for ±10V instrumentation and audio line-level routing |
| Guaranteed RON Flatness | ≤2Ω variation over full signal range - maintains consistent gain and THD across amplitude swing in audio paths |
| Break-Before-Make Timing | 70ns typical delay - prevents transient shorts in reconfigurable signal paths like PBX crosspoints |
| Low Charge Injection | ±30pC max - minimizes voltage glitches in sample-and-hold and switched-capacitor circuits |
| Pin Compatibility | Direct replacement for DG411/DG412/DG413 in 16-pin DIP - simplifies legacy design upgrades without PCB revision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX313CPE+ | Four NO channels only; no NC functionality; identical RON, matching, and supply specs | Suitable where all paths must be open by default (e.g., safety interlocks) | Select MAX313CPE+ when normally-open behavior is required for all four channels. |
| ADG412BNZ | Quad SPST, 35Ω RON (typ), ±15V supply, no guaranteed RON match spec, 16-pin PDIP | Higher on-resistance limits use in low-voltage precision paths; lower crosstalk (−80dB) | Choose ADG412BNZ only if cost sensitivity outweighs need for sub-2Ω matching and <10Ω RON. |
Compared with MAX313CPE+, the MAX314CPE+ adds fail-safe NC paths for critical signal retention, while ADG412BNZ trades RON performance for broader process heritage and lower unit cost - neither offers pin-compatible drop-in replacement without logic inversion or layout review.

FAQ
What is the operating temperature range for MAX314CPE+?
The MAX314CPE+ is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is defined by the 'C' suffix in the part number and validated per Maxim's production testing. The device maintains full electrical specifications - including 6.5Ω typical on-resistance and ≤2.5nA off-leakage at +85°C - across this range. For extended temperature applications, consider MAX314EPE+ (−40°C to +85°C) or MAX314MJE (−55°C to +125°C).
Does MAX314CPE+ support single-supply operation?
Yes, MAX314CPE+ supports single-supply operation from +4.5V to +30V. In this mode, V− must be connected to GND, and analog signals swing from 0V to V+. The device retains rail-to-rail signal handling and all key specs - including 6.5Ω typical on-resistance and >96dB crosstalk - under single-supply conditions. Logic inputs remain compatible with 3V or 5V CMOS/TTL levels via the VL pin.
How does the channel configuration of MAX314CPE+ differ from MAX312CPE+ and MAX313CPE+?
MAX314CPE+ integrates two normally closed (NC) switches (IN1/IN4 control NC1/NC4) and two normally open (NO) switches (IN2/IN3 control NO2/NO3). In contrast, MAX312CPE+ has four NC channels, and MAX313CPE+ has four NO channels. This hybrid configuration enables fail-safe signal retention (via NC paths) alongside on-demand routing (via NO paths), making MAX314CPE+ uniquely suited for PBX crosspoint and redundant sensor interface applications.
Is MAX314CPE+ pin-compatible with industry-standard analog switches?
Yes, MAX314CPE+ is pin-compatible with DG411, DG412, and DG413 in the 16-pin PDIP package. Pin assignments for COM, NO/NC, IN, V+, V−, GND, and VL match exactly, allowing direct substitution without PCB modification. However, note that DG411 is quad NO, DG412 is quad NC, and DG413 is dual NO/dual NC - so logic mapping and default state behavior must be verified in the target application.
What is the maximum analog signal voltage range supported by MAX314CPE+?
MAX314CPE+ supports analog signals from V− to V+ - up to ±20V with dual supplies or 0V to +30V with single supply. Absolute maximum ratings allow V+ to +44V and V− to −44V, but operational signal range is constrained by supply rails. For example, with ±15V supplies, the usable analog range is ±10V (per datasheet conditions); exceeding this may increase on-resistance variation or leakage. Always reference the Electrical Characteristics tables for guaranteed performance bounds.
