Analog Devices Inc./Maxim Integrated MAX4700EPE

Overview

MAX4700EPE from Maxim Integrated is a dual SPST CMOS analog switch with one normally closed (NC) and one normally open (NO) channel, guaranteed break-before-make switching, 1.25Ω max on-resistance, ±4.5V to ±20V dual-supply or +4.5V to +36V single-supply operation, and rail-to-rail signal handling - ideal for precision data acquisition and test equipment where channel isolation and timing control are critical.

For engineers reviewing the MAX4700EPE datasheet, MAX4700EPE pinout, MAX4700EPE application, or MAX4700EPE equivalent, key selection criteria include guaranteed break-before-make timing (5–125 ns), R_ON matching (≤0.3Ω), off-isolation (−53 dB), charge injection (±60 pC), and compatibility with TTL/CMOS logic across full supply range.

Technical Context

The MAX4700EPE implements complementary MOSFET-based SPST switches with independent digital control inputs (IN1, IN2), separate logic supply (VL), and dual analog supplies (V+, V−). Its break-before-make architecture prevents momentary shorting between COM1/COM2 and NC1/NO1 during state transitions.

It supports rail-to-rail analog signals up to ±20V (dual) or +36V (single), with input voltage ranges referenced to V+ and V−, and features internal ESD protection (>2 kV per Method 3015.7). Off-leakage is specified at ≤5 nA at +85°C, enabling high-impedance signal path integrity.

Key Specifications

Pinout & Package

MAX4700EPE is housed in a 16-pin plastic DIP package (0.300" wide), with through-hole mounting and industry-standard footprint. Pin functions are electrically validated per Maxim's official pin configuration diagram for MAX4700.

FAQ

What is the guaranteed break-before-make time for MAX4700EPE?

The MAX4700EPE guarantees a break-before-make interval of 5 ns minimum to 125 ns maximum under dual-supply conditions (V+ = +15V, V− = −15V). This specification is explicitly tested and documented in the Electrical Characteristics table for MAX4700EPE, ensuring no overlap between NC and NO conduction paths during switching transitions - a critical requirement for avoiding signal shorts in precision routing applications.

Does MAX4700EPE support single-supply operation?

Yes, MAX4700EPE supports single-supply operation from +4.5V to +36V, with V− connected to GND. In this configuration, the device maintains rail-to-rail signal handling from 0V to V+, and all key specifications - including 1.25Ω max R_ON, 0.3Ω R_ON match, and −53 dB off-isolation - remain valid per the Single-Supply Electrical Characteristics table in the MAX4700EPE datasheet.

What is the maximum off-leakage current of MAX4700EPE at elevated temperature?

The MAX4700EPE specifies a maximum off-leakage current of 5 nA at +85°C, tested across NO_ and NC_ terminals. This value is 100% production-tested at maximum-rated hot temperature and correlated at +25°C, ensuring reliable performance in high-temperature industrial environments such as automated test equipment enclosures or industrial PLC I/O modules.

Can MAX4700EPE be used with TTL logic levels?

Yes, MAX4700EPE accepts TTL/CMOS-compatible logic inputs across its full supply range: logic high (VIN_H) is guaranteed ≥2.4V, logic low (VIN_L) is guaranteed ≤0.8V, and input current remains within ±0.5 µA. The dedicated VL pin allows independent logic supply biasing, enabling seamless interface with 3.3V or 5V microcontrollers without level shifters - a verified design feature of the MAX4700EPE.

What package type is used for MAX4700EPE?

MAX4700EPE is supplied in a 16-pin plastic DIP (dual in-line package) with 0.300" body width and through-hole mounting. This package matches the industry-standard PDIP-16 footprint, supports manual prototyping and wave soldering, and is explicitly listed in Maxim's Ordering Information table for the MAX4700EPE variant with −40°C to +85°C operating temperature range.
