Analog Devices Inc./Maxim Integrated MAX314CPE

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, ±4.5V to ±20V dual-supply or +4.5V to +30V single-supply operation, and 2.5nA max off-leakage at +85°C. It is used in precision audio routing and data acquisition systems requiring low distortion and tight channel matching.

For engineers reviewing the MAX314CPE datasheet, MAX314CPE pinout, MAX314CPE application, or MAX314CPE equivalent, key selection criteria include verified NC/NO channel configuration, guaranteed R_ON flatness (≤2Ω), break-before-make timing (70ns typ), ESD tolerance (>2000V per Method 3015.7), and compatibility with DG411/DG412/DG413 footprint for legacy system upgrades.

Technical Context

The MAX314CPE implements a complementary MOSFET architecture enabling bidirectional conduction and rail-to-rail analog signal switching across its four independent SPST channels. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL, while analog terminals support full-range operation from V− to V+.

Each channel exhibits tightly controlled R_ON variation (≤2Ω flatness over ±10V signal range) and matched on-resistance (≤1.5Ω difference between any two channels), critical for minimizing gain error in multiplexed instrumentation and balanced audio paths. Break-before-make timing is specified only for the MAX314 variant and measured at 70ns typical under defined load conditions.

FAQ

What is the operating temperature range for MAX314CPE?

The MAX314CPE is rated for 0°C to +70°C ambient operation, as indicated by the 'C' suffix in the part number. This commercial-grade temperature range is validated across all electrical specifications including on-resistance, leakage, and switching times. The device is not characterized for extended industrial or military ranges unless marked with 'E' or 'M' suffixes. Always verify thermal derating in high-power-density PCB layouts.

Does MAX314CPE support single-supply operation?

Yes, MAX314CPE supports single-supply operation from +4.5V to +30V. In this mode, V− is connected to GND, and analog signals swing from 0V to V+. The device maintains rail-to-rail signal handling, 6.5Ω typical R_ON, and ≤2.5nA off-leakage at +85°C. Logic inputs remain compatible with 5V TTL/CMOS levels via the VL pin, which may be tied to V+ or a separate 5V rail.

How does the NC/NO configuration work in MAX314CPE?

In MAX314CPE, pins IN1 and IN4 control NC1 and NC4 (normally closed), while IN2 and IN3 control NO2 and NO3 (normally open). When an input is logic low (0), its NC switch closes and its NO switch opens; when high (1), the NC opens and NO closes. This dual-mode structure allows fail-safe path selection-for example, maintaining a default signal path until actively switched-without external pull resistors or auxiliary logic.

Is MAX314CPE pin-compatible with DG411/DG412/DG413?

Yes, MAX314CPE is pin-compatible with DG411 (quad NO), DG412 (quad NC), and DG413 (dual NO + dual NC) in 16-pin DIP, SO, and TSSOP packages. Pin assignments for COM, NO, NC, IN, V+, V−, GND, and VL match exactly. No PCB layout changes are required for migration, though designers should confirm logic polarity alignment and validate timing under actual load conditions.

What is the maximum analog signal voltage range supported by MAX314CPE?

MAX314CPE supports analog signals from V− to V+, enabling true rail-to-rail operation. With ±15V dual supplies, the full range is ±15V; with +12V/0V single supply, it is 0V to +12V. Absolute maximum ratings allow V+ up to +44V and V− down to −44V, but functional analog range remains bounded by the applied supply rails. Exceeding V+ or V− at analog pins triggers internal clamping diodes, limiting safe continuous signal swing to the supply boundaries.
