Analog Devices Inc./Maxim Integrated MAX339MJE

Overview

MAX339MJE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer designed to route one of four analog inputs per section to a common bidirectional output under 2-bit binary address control. It features ≤400Ω on-resistance, <20pA off-leakage at +25°C, 1.5pC typical charge injection, and operates from ±4.5V to ±20V dual supplies or +4.5V to +30V single supply. It is used in precision military-grade data-acquisition systems requiring rail-to-rail signal handling and ESD protection >2000V.

For engineers reviewing the MAX339MJE datasheet, MAX339MJE pinout, MAX339MJE application, or MAX339MJE equivalent, key selection criteria include guaranteed -55°C to +125°C operation, CERDIP-16 hermetic packaging, low leakage across temperature extremes, and compatibility with TTL/CMOS logic levels over full supply range.

Technical Context

The MAX339MJE implements dual independent 4:1 analog switch arrays using Maxim's 44V silicon-gate CMOS process, enabling symmetric conduction in both directions with matched on-resistance (≤10Ω between channels). Its decode logic accepts A0/A1 address inputs and an active-low enable (EN), supporting mux or demux operation without external components.

All digital inputs are TTL-compatible (+0.8V to +2.4V) across the full -55°C to +125°C temperature range and ±4.5V to ±18V supply range. The device supports rail-to-rail analog signal handling up to ±20V (dual) or +30V (single), with internal clamping diodes protecting NO, COM, and control pins against overvoltage.

FAQ

What is the maximum allowable voltage difference between V+ and V− for MAX339MJE?

The absolute maximum voltage difference between V+ and V− for MAX339MJE is 44V, as specified in the Absolute Maximum Ratings table. This limit applies regardless of individual rail values - for example, +24V on V+ and -20V on V− is acceptable (44V total), but +25V and -20V would exceed the rating. Exceeding this value risks permanent damage due to junction breakdown.

Does MAX339MJE support single-supply operation, and how is it configured?

Yes, MAX339MJE supports single-supply operation from +4.5V to +30V. To configure, connect V− to GND (not left floating), tie EN high (via pull-up if needed), and ensure all analog signals remain within 0V to V+ range. The device retains full TTL/CMOS logic compatibility and rail-to-rail analog handling, though on-resistance increases slightly compared to dual-supply mode.

How does the charge injection specification of MAX339MJE impact sample-and-hold circuit design?

The 1.5pC typical charge injection of MAX339MJE directly determines the voltage glitch on a hold capacitor: ΔV = Q/C. For a 100pF capacitor, this yields ~15mV error - unacceptable for 12-bit+ accuracy. Designers must use larger hold capacitors (e.g., 1nF → 1.5mV) or implement correlated double sampling. The guaranteed spec allows deterministic error budgeting unlike non-specified alternatives.

Is MAX339MJE pin-compatible with DG509A, and what design changes are needed for replacement?

Yes, MAX339MJE is a pin-compatible upgrade for DG509A in CERDIP-16 packages. No PCB layout changes are required. However, due to lower on-resistance and tighter leakage specs, users should verify that existing drive strength and timing margins remain sufficient - particularly in high-speed switching applications where reduced transition time may affect setup/hold windows.

What is the significance of the "M" prefix in MAX339MJE's part number?

The "M" prefix in MAX339MJE denotes the military temperature grade (-55°C to +125°C), distinguishing it from commercial ("C") and extended ("E") variants. It also indicates qualification to MIL-PRF-38535 requirements, including screening for burn-in, temperature cycling, and hermeticity - essential for deployment in defense and space systems where reliability under thermal stress is non-negotiable.
