Analog Devices Inc./Maxim Integrated MAX314EPE+

Overview

MAX314EPE+ 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, 10Ω max on-resistance, 1.5Ω max on-resistance matching between channels, and guaranteed operation from -40°C to +85°C in a 16-pin plastic DIP package. It supports rail-to-rail analog signal handling and is used in audio routing, test equipment, and data acquisition systems where bidirectional low-distortion switching is required.

For engineers reviewing the MAX314EPE+ datasheet, MAX314EPE+ pinout, MAX314EPE+ application, or MAX314EPE+ equivalent, key selection criteria include its dual-supply range (±4.5V to ±20V), break-before-make timing (70ns typ), crosstalk performance (>96dB at 20kHz), and ESD tolerance (>2000V per Method 3015.7).

Technical Context

The MAX314EPE+ implements a CMOS transmission-gate architecture enabling symmetrical conduction in both directions, with guaranteed R_ON flatness ≤2Ω over ±10V signal range and <2.5nA off-leakage at +85°C. Its logic interface accepts TTL/CMOS-compatible inputs referenced to VL (2.4V high, 0.8V low) independent of analog supply rails.

It features integrated overvoltage protection clamping diodes on all analog terminals (COM, NO, NC), allowing safe operation with signals exceeding V+ or falling below V− when external blocking diodes are added. The device maintains consistent switching performance across single-supply (+4.5V to +30V) and dual-supply (±4.5V to ±20V) configurations without reconfiguration.

FAQ

What is the maximum analog signal voltage range supported by the MAX314EPE+?

The MAX314EPE+ supports an analog signal range from V− to V+ with dual supplies (±4.5V to ±20V), or from 0V to V+ with single supplies (+4.5V to +30V). Under ±15V dual-supply conditions, the guaranteed signal range is ±10V, enabling rail-to-rail operation without clipping in audio and sensor interfaces.

Does the MAX314EPE+ require external pull-up or pull-down resistors on its logic inputs?

No, the MAX314EPE+ logic inputs (IN1–IN4) are TTL/CMOS-compatible with guaranteed thresholds of 2.4V (high) and 0.8V (low) when referenced to VL. Internal input structure eliminates need for external biasing, simplifying interface with microcontrollers and FPGAs operating at 3.3V or 5V logic levels.

How does the MAX314EPE+ handle overvoltage conditions on analog terminals?

The MAX314EPE+ integrates clamp diodes on all analog pins (COM, NO, NC) that conduct when signals exceed V+ or fall below V−. To prevent damage, external series current-limiting resistors must be used with blocking diodes per Figure 1 in the datasheet-ensuring safe operation with transient overvoltages up to ±44V absolute maximum ratings.

Is the MAX314EPE+ pin-compatible with the DG413 analog switch?

Yes, the MAX314EPE+ is explicitly pin-compatible with the DG413, sharing identical pin assignments, electrical interface, and functional behavior for the two NO/two NC configuration. This allows direct substitution in existing DG413-based designs without PCB modification or firmware changes.

What is the typical charge injection value of the MAX314EPE+, and why does it matter?

The MAX314EPE+ exhibits ±30pC typical charge injection, measured at VCOM = ±10V. This low value minimizes voltage glitches on high-impedance nodes such as sample-and-hold capacitors or sensor amplifier inputs-preserving DC accuracy and reducing settling time in precision data acquisition circuits using the MAX314EPE+.
