Product details
Overview
MAX14752EUE+T from Maxim Integrated is an 8-channel (8-to-1) high-voltage analog multiplexer IC designed for precision signal routing in industrial and test equipment. It delivers 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 MAX14752EUE+T datasheet, MAX14752EUE+T pinout, MAX14752EUE+T application, or MAX14752EUE+T equivalent, key selection criteria include high-voltage analog channel count, low RON flatness, leakage-critical off-isolation, and compatibility with legacy DG408-based layouts.
Technical Context
The MAX14752EUE+T implements a CMOS-based 8-to-1 analog multiplexer architecture with fully bidirectional conduction and no power-supply sequencing requirement. Its EN input defines flexible logic thresholds for S0–S2 control lines, enabling interoperability with diverse host logic levels.
It supports asymmetric dual supplies (e.g., +36V/–10V), maintains rail-to-rail analog signal handling, and features internal ESD protection diodes usable for beyond-the-rail input clamping when paired with external current-limiting resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel Configuration | Single 8-to-1 analog multiplexer - routes one of eight bidirectional inputs to a common output. |
| Supply Range | +20V to +72V single supply or ±10V to ±36V dual supply - enables direct interfacing with high-voltage sensors and actuators. |
| On-Resistance (RON) | 60Ω typical - minimizes signal attenuation and gain error in precision measurement paths. |
| RON Flatness | 0.03Ω typical over full common-mode range - ensures consistent channel-to-channel gain matching in multi-sensor acquisition. |
| Off-Isolation | 65dB at 100kHz - suppresses crosstalk between unselected channels in dense analog routing. |
| Charge Injection | 200pC - limits voltage glitch amplitude on sampled-hold nodes during channel switching. |
| Enable Turn-On Time | 1µs typical - supports high-throughput scanning in automated test equipment. |
Pinout & Package
MAX14752EUE+T is housed in a 16-pin TSSOP package (JEDEC MO-153, 4.4mm × 5.0mm), RoHS-compliant and pin-compatible with industry-standard DG408.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 15, 16 | S0, S2, S1 | Binary channel-select inputs - decode 000–111 to route IN0–IN7 to OUT. |
| 2 | EN | Enable input - high enables mux; voltage level sets logic threshold for S0–S2. |
| 3, 13 | VSS, VDD | Negative/positive supply rails - support ±36V dual or +72V single operation. |
| 4–7, 9–12 | IN0–IN7 | Bidirectional analog inputs - handle rail-to-rail signals up to supply limits. |
| 8 | OUT | Bidirectional analog output - shares same voltage range and current capability as inputs. |
| 14 | GND | Reference ground - tied to VSS in single-supply mode; bypassed to VSS with 1µF capacitor in dual-supply mode. |
Key Features
| Feature | Design Value |
|---|---|
| Flexible Logic Interface | EN-defined logic thresholds allow direct connection to 1.8V–12V control logic without level shifters. |
| Rail-to-Rail Signal Handling | Supports analog signals from VSS to VDD - eliminates need for external signal conditioning in wide-dynamic-range systems. |
| Low On-Leakage Current | 20nA max at +25°C - preserves accuracy in high-impedance sensor front-ends and sample-and-hold circuits. |
| Break-Before-Make Switching | 10µs guaranteed interval - prevents momentary shorting between input channels during reconfiguration. |
| DG408 Pin Compatibility | Direct drop-in replacement for legacy DG408 designs - reduces redesign time and qualification effort. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX14753EUE+T | Dual 4-to-1 configuration instead of single 8-to-1; identical RON, leakage, and supply specs. | Preferred where independent channel groups (e.g., two sensor banks) require simultaneous access. | Select MAX14753EUE+T when system architecture requires parallel 4-channel routing rather than sequential 8-channel scanning. |
| DG408DJ | Higher 80Ω typical RON, wider 0.5Ω RON matching spec, lower 50V max supply, no asymmetric supply support. | Legacy designs with relaxed accuracy or lower voltage requirements; lacks modern leakage and flatness performance. | Choose DG408DJ only for cost-sensitive replacements where 60Ω RON and 0.03Ω flatness are not required. |
Compared with MAX14753EUE+T, the MAX14752EUE+T offers consolidated 8-channel control with simpler address decoding; versus DG408DJ, it delivers superior precision, higher voltage headroom, and enhanced thermal stability - critical for next-generation industrial instrumentation.

FAQ
What is the maximum supply voltage rating for MAX14752EUE+T?
The MAX14752EUE+T supports up to +72V on VDD with VSS at GND in single-supply mode, or ±36V in dual-supply mode. Absolute maximum ratings specify VDD to VSS up to +72V, but continuous operation above ±36V or +72V is not guaranteed and may risk reliability. Always observe the recommended operating conditions in the datasheet for MAX14752EUE+T.
Does MAX14752EUE+T support asymmetric dual supplies?
Yes, MAX14752EUE+T supports asymmetric dual supplies - for example, +36V on VDD and –10V on VSS - as explicitly confirmed in the Applications Information section. This capability allows adaptation to non-symmetrical system power rails while maintaining full analog signal range from VSS to VDD, a feature not supported by legacy devices like DG408.
What is the function of the EN pin on MAX14752EUE+T?
The EN pin on MAX14752EUE+T serves as both an enable input and a logic reference: driving EN high activates the multiplexer, and the applied EN voltage defines the high/low thresholds for S0, S1, and S2. For instance, with EN = +3.3V, VIH for select lines is 0.75 × 3.3V = +2.475V, enabling direct interface with 3.3V logic without external level translation.
Can MAX14752EUE+T be used in rail-to-rail signal paths?
Yes, MAX14752EUE+T supports true rail-to-rail analog operation: input and output signals can swing from VSS to VDD under all specified supply conditions. This is enabled by its CMOS process and internal architecture, allowing direct connection to sensors or DACs operating at supply rails - a key advantage over older multiplexers with limited signal headroom.
Is MAX14752EUE+T pin-compatible with DG408?
Yes, MAX14752EUE+T is explicitly stated as pin-compatible with the industry-standard DG408 in the General Description and Ordering Information sections. Both use the same 16-pin TSSOP package and identical pin functions (S0–S2, EN, IN0–IN7, OUT, VDD, VSS, GND), enabling drop-in replacement without PCB layout changes.
