Analog Devices Inc./Maxim Integrated MAX14753EUE+T

Overview

MAX14753EUE+T from Maxim Integrated is a dual 4-channel high-voltage analog multiplexer IC designed for precision signal routing in industrial and test equipment. It features 60Ω typical on-resistance, 0.03Ω typical on-resistance flatness, ±36V dual-supply or +72V single-supply operation, and operates across –40°C to +85°C. It serves as a bidirectional, rail-to-rail switch in programmable logic controllers and ATE systems.

For engineers reviewing the MAX14753EUE+T datasheet, MAX14753EUE+T pinout, MAX14753EUE+T application, or MAX14753EUE+T equivalent, key selection criteria include its dual 4-to-1 topology, 72V absolute max supply rating, low leakage (≤20nA on-state, ≤10nA off-state), break-before-make timing (10µs), and pin compatibility with DG409.

Technical Context

The MAX14753EUE+T implements two independent 4-to-1 analog multiplexers sharing common enable (EN) and select (S0/S1) inputs, each with fully bidirectional signal paths and matched channel characteristics. Its CMOS process enables symmetric conduction, rail-to-rail analog voltage handling, and no power-supply sequencing requirement.

Logic level flexibility is achieved via EN-defined thresholds: S0/S1 high/low levels scale proportionally to EN voltage (0.75×VEN / 0.25×VEN), supporting interface compatibility with diverse controller I/O. The device maintains stable R_ON flatness (0.03Ω typ) over ±20V common-mode range and delivers 20MHz bandwidth with 62dB crosstalk suppression at 1MHz.

FAQ

What supply configurations does the MAX14753EUE+T support?

The MAX14753EUE+T supports dual supplies from ±10V to ±36V, single supplies from +20V to +72V, and asymmetric configurations (e.g., +36V/–10V). It requires no power-supply sequencing, and GND connects directly to VSS in single-supply mode. Bypass capacitors (1µF ceramic) are mandatory at VDD and VSS pins per the datasheet layout guidelines for MAX14753EUE+T stability.

Is the MAX14753EUE+T pin-compatible with the DG409?

Yes, the MAX14753EUE+T is pin-compatible with the DG409 in its 16-pin TSSOP package. Pin functions match exactly: S0/S1/EN control inputs, INA0–INA3/INB0–INB3 analog inputs, OUTA/OUTB outputs, and VDD/VSS/GND power terminals align identically. This allows direct replacement without PCB modification, provided the higher voltage ratings and improved leakage specs of MAX14753EUE+T are leveraged in the design.

What is the maximum continuous current per channel for the MAX14753EUE+T?

The MAX14753EUE+T specifies a maximum continuous current of ±5mA per channel under normal operation, as defined in the "Current Through Multiplexer" parameter. Exceeding this may induce internal leakage to VSS but will not damage the device if total power dissipation remains within the 890mW limit at TA = +70°C. Absolute maximum rating is 100mA per terminal, but sustained operation above ±5mA is not recommended for accuracy or reliability.

How does the EN input define logic levels for S0 and S1 on the MAX14753EUE+T?

On the MAX14753EUE+T, the EN input voltage sets the logic thresholds for S0 and S1: VIH = 0.75 × VEN and VIL = 0.25 × VEN. For example, with EN = +3.3V, S0/S1 recognize logic high above 2.475V and low below 0.825V. This scalable interface allows seamless connection to 1.8V, 3.3V, or 5V controllers without level shifters, making MAX14753EUE+T adaptable across diverse host systems.

Does the MAX14753EUE+T support beyond-the-rail input voltages?

The MAX14753EUE+T tolerates input voltages beyond its supply rails-up to the absolute maximum ratings of –2V to (VDD – VSS + 2V)-using internal ESD diodes. For safe operation, external series resistors must limit fault current to ≤100mA. Figure 11 in the MAX14753EUE+T datasheet shows the recommended clamping network. Operation remains functional on enabled channels even during clamping on inactive ones.
