Analog Devices Inc./Maxim Integrated MAX14753EUE+

Overview

MAX14753EUE+ from Maxim Integrated is a dual 4-channel high-voltage analog multiplexer IC designed for precision signal routing in industrial and test equipment. It supports ±10V to ±36V dual supplies or +20V to +72V single supply, delivers 60Ω typical on-resistance with 0.03Ω flatness, and operates across –40°C to +85°C. It routes bidirectional analog signals in programmable logic controllers and ATE systems.

For engineers reviewing the MAX14753EUE+ datasheet, MAX14753EUE+ pinout, MAX14753EUE+ application, or MAX14753EUE+ equivalent, key selection criteria include rail-to-rail signal handling, low leakage (≤20nA on-state), break-before-make timing (10µs), asymmetric supply capability, and pin compatibility with DG409.

Technical Context

The MAX14753EUE+ implements two independent 4-to-1 analog multiplexers sharing common enable (EN) and select (S0/S1) inputs. Each channel conducts bidirectionally with matched on-resistance and minimal flatness variation over ±20V common-mode range.

Logic level flexibility is achieved via EN voltage definition: S0/S1 thresholds scale as 0.25×VEN (low) and 0.75×VEN (high), enabling interface with 3.3V, 5V, or up to +11V control logic without level shifters.

Key Specifications

Pinout & Package

MAX14753EUE+ is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm), RoHS-compliant and pin-compatible with industry-standard DG409.

FAQ

What supply configurations does the MAX14753EUE+ support?

The MAX14753EUE+ operates with dual supplies from ±10V to ±36V or a single supply from +20V to +72V. It also supports asymmetric configurations-for example, +36V on VDD and –10V on VSS-without derating. This flexibility allows integration into diverse industrial power architectures while maintaining full 60Ω typical on-resistance and 0.03Ω flatness across all supported ranges. The MAX14753EUE+ requires no power-supply sequencing.

How does the EN pin define logic thresholds for S0 and S1 on the MAX14753EUE+?

On the MAX14753EUE+, the EN pin voltage sets the logic thresholds for S0 and S1: VIH = 0.75 × VEN and VIL = 0.25 × VEN. This allows direct interfacing with 3.3V, 5V, or even +11V control logic without external level shifters. For example, with VEN = +3.3V, S0/S1 recognize >2.475V as high and <0.825V as low-ensuring reliable operation across varied host controller voltage domains. The MAX14753EUE+ datasheet specifies this behavior across –40°C to +85°C.

Can the MAX14753EUE+ handle input voltages beyond its supply rails?

The MAX14753EUE+ supports beyond-the-rail inputs only within its absolute maximum ratings (–2V to VDD–VSS+2V). For sustained operation, inputs must remain within VSS to VDD. However, internal ESD diodes clamp transient overvoltages: series current-limiting resistors (calculated per datasheet Figure 11) protect against ±100mA fault currents. The MAX14753EUE+ does not tolerate continuous beyond-rail operation-designs requiring true beyond-rail capability need external clamping or dedicated overvoltage-tolerant switches.

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

The MAX14753EUE+ supports ±5mA continuous current per active channel under normal operating conditions. Exceeding this limit induces increased leakage from the conducting channel to VSS but does not damage the device if total power dissipation remains below 890mW (at TA = +70°C). The MAX14753EUE+'s 60Ω typical on-resistance means 5mA generates only 1.5mW per channel-well within safe thermal limits. Always verify current limits using worst-case RON and signal swing in your design.

Is the MAX14753EUE+ pin-compatible with the DG409?

Yes, the MAX14753EUE+ is pin-compatible with the industry-standard DG409 in the 16-pin TSSOP package. Pin functions-including S0, S1, EN, INA0–INA3, INB0–INB3, OUTA, OUTB, VDD, VSS, and GND-match identically. No PCB layout changes are required for drop-in replacement. However, the MAX14753EUE+ improves upon the DG409 with 40% lower typical on-resistance (60Ω vs. 100Ω), 0.03Ω vs. 0.5Ω RON flatness, and enhanced off-isolation (65dB vs. 60dB), making it a performance upgrade path.
