Analog Devices Inc./Maxim Integrated MAX392EPE

Overview

MAX392EPE from Maxim Integrated is a precision quad SPST analog switch with four normally open (NO) channels, designed for low-leakage signal routing in ±5V, +5V, or +3V systems. It delivers 60Ω max on-resistance at +5V, 100pA max off-leakage, 5pC max charge injection, and operates across –40°C to +85°C in 16-pin plastic DIP. It is used in battery-powered test equipment and precision sample-and-hold circuits.

For engineers reviewing the MAX392EPE datasheet, MAX392EPE pinout, MAX392EPE application, or MAX392EPE equivalent, this page provides verified electrical specs, thermal operating limits, leakage behavior over temperature, switching timing under dual/single supply conditions, and real-world design guidance for analog signal path integrity.

Technical Context

The MAX392EPE implements CMOS transmission-gate architecture with substrate tied to V+, enabling rail-to-rail analog signal handling from V– to V+. Its logic inputs are TTL/CMOS-compatible, and internal ESD protection exceeds 2000V per Method 3015.7.

It guarantees channel-to-channel R_ON matching ≤2Ω and R_ON flatness ≤4Ω over the full signal range under ±5V supplies - critical for multi-channel instrumentation where gain/offset tracking matters. Charge injection is tightly controlled (<5pC), minimizing transient errors in sampling nodes.

Key Specifications

Pinout & Package

MAX392EPE uses a 16-pin plastic DIP (P16-1) package with through-hole mounting and no exposed pad. Pin 13 is V+, pin 4 is V–, pin 5 is GND, pins 1/8/9/16 are IN1–IN4, pins 2/7/10/15 are COM1–COM4, and pins 3/6/11/14 are NO1–NO4. Pin 12 is N.C. (not internally connected).

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad SPST analog switch applications.

Compared with ADG1412BRUZ and TS5A3157DCKR, the MAX392EPE uniquely combines quad NO topology, –40°C to +85°C DIP packaging, ±5V rail-to-rail operation, and guaranteed sub-2Ω R_ON matching - making it irreplaceable for legacy-reliant, high-reliability analog multiplexing where through-hole assembly and thermal stability are mandatory.

Availability

MAX392EPE is available at Aetrix Electronics and suitable for battery-operated test equipment, precision sample-and-hold circuits, heads-up displays, ±5V DAC/ADC interfaces, and industrial guidance systems requiring stable component supply across extended temperature ranges.

Supply support for MAX392EPE includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog and mixed-signal ICs for industrial, medical, and communications applications, with emphasis on low-power, high-reliability performance.

The MAX391/MAX392/MAX393 family was engineered specifically for high-fidelity analog signal routing in measurement and control systems where leakage, charge injection, and R_ON matching directly impact accuracy - especially in multiplexed data acquisition and sensor interface applications.

FAQ

What is the maximum allowable analog signal range for MAX392EPE when operated from ±5V supplies?

The MAX392EPE supports an analog signal range from V– to V+, i.e., –5V to +5V, when powered from ±5V supplies. This rail-to-rail capability is enabled by its CMOS transmission-gate architecture and substrate connection to V+. Exceeding these limits risks forward-biasing internal clamping diodes and violating absolute maximum ratings.

Does MAX392EPE require power-supply sequencing, and if so, what is the correct order?

Yes, MAX392EPE requires strict power-supply sequencing: V+ must be applied first, followed by V–, and then logic inputs. This sequence prevents latch-up and ensures proper internal biasing. If sequencing cannot be guaranteed, external blocking diodes (as shown in Figure 1 of the datasheet) should be added to V+ and V– pins - though this reduces usable analog range by ~1V.

What is the guaranteed on-resistance match between channels for MAX392EPE at +5V single supply?

At +5V single supply (V+ = +5V, V– = 0V), the MAX392EPE guarantees on-resistance match (ΔR_ON) of ≤2Ω across all four channels. This specification is tested per Note 4 in the Electrical Characteristics table and applies over the full operating temperature range (–40°C to +85°C), ensuring predictable channel-to-channel gain consistency.

Can MAX392EPE be used in a +3.3V-only system, and what are the key trade-offs?

Yes, MAX392EPE operates from +3.0V to +3.6V single supply. However, R_ON increases to 175Ω max (vs. 60Ω at +5V), t_ON extends to 400ns max (vs. 130ns), and analog signal range shrinks to 0V to V+. These trade-offs make it viable for low-speed, low-precision +3.3V applications but less suitable for high-bandwidth or low-distortion requirements.

Is there a drop-in replacement for MAX392EPE in 16-pin DIP that supports the same –40°C to +85°C temperature range?

No drop-in replacement exists in 16-pin DIP with identical –40°C to +85°C rating and quad NO functionality. The MAX392ESE (SO-16) and MAX392EUE (TSSOP-16) share electrical specs and temperature range but differ in package and pinout. Any substitution requires PCB redesign; no pin-compatible alternative is documented by Maxim or major distributors for the DIP variant.
