Analog Devices Inc./Maxim Integrated MAX353EPE+

Overview

MAX353EPE+ from Maxim Integrated is a precision quad SPST analog switch with two normally open (NO) and two normally closed (NC) channels, fabricated using a 44V silicon-gate process. It delivers <35Ω on-resistance (max), <2Ω channel-to-channel match, <3Ω on-resistance flatness over signal range, <10pC charge injection, and supports rail-to-rail analog signals up to ±15.5V in dual-supply mode - used in military radios and guidance systems requiring high channel matching and low leakage.

For engineers reviewing the MAX353EPE+ datasheet, MAX353EPE+ pinout, MAX353EPE+ application, or MAX353EPE+ equivalent, key selection criteria include guaranteed on-resistance matching across temperature, break-before-make timing for channel isolation, ESD >2000V compliance, and compatibility with ±4.5V to ±20V or +10V to +30V supplies.

Technical Context

The MAX353EPE+ implements four independent SPST switches in a single monolithic IC, with dedicated logic inputs (IN1–IN4) controlling individual NO/NC states per channel. Its CMOS-compatible inputs accept TTL/CMOS logic levels while maintaining low input loading, and internal substrate connection to V+ enables robust rail-to-rail analog signal handling up to 44V breakdown voltage.

It operates under bipolar (±4.5V to ±20V) or single-supply (+10V to +30V) conditions, with VL pin configurable for TTL (5V) or CMOS (tied to V+) logic thresholds. Break-before-make timing (25ns typ.) is explicitly specified only for MAX353 variants, ensuring transient-free switching in sample-and-hold and test equipment applications.

Key Specifications

Pinout & Package

MAX353EPE+ uses a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard pin spacing. Pin 13 is V+, pin 4 is V−, pin 5 is GND, pin 12 is VL, and pins 1–4 and 14–16 serve as logic inputs (IN1–IN4) and analog terminals (COM1–COM4, NO1/NO4, NC2/NC3).

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and high-reliability ICs for demanding industrial, automotive, and defense applications.

The MAX351/MAX352/MAX353 family was engineered specifically for high-fidelity analog signal routing in mission-critical systems where channel matching, low leakage, and rail-to-rail operation are essential - exemplified by the MAX353EPE+'s dual NO/NC topology and guaranteed dynamic parameters.

FAQ

What is the maximum analog signal voltage range supported by the MAX353EPE+?

The MAX353EPE+ supports rail-to-rail analog signals up to ±15.5V when operated with dual supplies (e.g., V+ = +16.5V, V− = −16.5V), limited by its 44V breakdown rating. In single-supply mode (+10V to +30V), the analog range extends from V− (typically GND) to V+, enabling full-scale signal handling without external clamping. This capability is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official datasheet.

Does the MAX353EPE+ provide break-before-make functionality, and is it guaranteed across temperature?

Yes, the MAX353EPE+ provides break-before-make timing of 25ns typical (as measured in Figure 3 of the datasheet), and this parameter is guaranteed over the full −40°C to +85°C operating range. Unlike MAX351/MAX352, only the MAX353 variant includes this feature - it ensures no overlap between NO and NC conduction paths during logic transitions, preventing transient shorts in safety-critical routing.

How does the VL pin function on the MAX353EPE+, and what happens if it's left unconnected?

The VL pin on the MAX353EPE+ sets the logic input threshold: connect to +5V for TTL compatibility or tie to V+ for CMOS-level inputs. Leaving VL floating is not permitted - it will cause undefined logic behavior and potential device malfunction. The datasheet explicitly requires VL to be externally biased; no internal pull-up or pull-down is provided, and operation outside recommended VL conditions invalidates all logic-level specifications.

Can the MAX353EPE+ operate with unbalanced supplies such as +24V and −5V?

Yes, the MAX353EPE+ supports unbalanced supplies - the datasheet confirms operation with configurations like +24V and −5V, provided the difference between V+ and V− does not exceed +44V. In such cases, the analog signal range is constrained by the more limiting rail (e.g., −5V to +24V), and VL must still be set appropriately (e.g., +5V for TTL). This flexibility is validated in the "Operation with Supplies Other than ±15V" section.

What is the guaranteed on-resistance match specification for the MAX353EPE+, and under what conditions does it apply?

The MAX353EPE+ guarantees on-resistance match of <2Ω between channels, but this specification applies only under bipolar-supply operation (e.g., ±15V), as explicitly noted in datasheet footnote 5. It is not guaranteed for single-supply use. The match is tested across the full operating temperature range (−40°C to +85°C) and remains stable due to monolithic construction and matched transistor design - critical for differential signal integrity.
