Product details
Overview
MAX309EPE+ from Maxim Integrated is a precision differential 2-of-4 CMOS analog multiplexer designed for bidirectional signal routing in high-fidelity measurement and control paths. It delivers <100Ω on-resistance (max), <5Ω channel-to-channel matching, <10pC charge injection, and operates from ±5V to ±20V or +5V to +30V supplies - enabling use in military radios, automatic test equipment, and battery-operated systems requiring rail-to-rail signal handling.
For engineers reviewing the MAX309EPE+ datasheet, MAX309EPE+ pinout, MAX309EPE+ application, or MAX309EPE+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤7Ω over ±10V range), low leakage (<5nA NO-off at +85°C), fast transition time (<250ns), TTL/CMOS logic compatibility, and plug-in upgrade capability for DG409/DG509A.
Technical Context
The MAX309EPE+ implements a fully differential 2-of-4 switching architecture with dual independent COM outputs (COMA and COMB) and two sets of four bidirectional analog inputs (NO1A–NO4A and NO1B–NO4B). Its silicon-gate CMOS process ensures matched switch characteristics across channels and stable performance over temperature (−40°C to +85°C).
It supports break-before-make switching with ≤450ns tOPEN (typ), enables single- or dual-supply operation without external level-shifting, and integrates electrostatic discharge protection >2000V. Logic decoding is handled internally via A0/A1 address lines and EN enable, eliminating external decode logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | <100Ω max - ensures minimal signal attenuation and gain error in precision gain-setting or sensor front-end paths |
| On-Resistance Matching | <5Ω max - enables accurate ratiometric measurements and matched channel switching in differential signal chains |
| Charge Injection | <10pC - reduces voltage glitch and settling error in sample-and-hold circuits using small hold capacitors |
| NO-Off Leakage | <5nA at +85°C - maintains accuracy in high-impedance sensor multiplexing (e.g., thermocouples, pH electrodes) |
| Transition Time | <250ns - supports multiplexing of signals up to ~1.5MHz without significant edge distortion |
| Analog Signal Range | ±10V (dual supply) - allows full utilization of ±15V rails while preserving linearity and low distortion |
| Supply Range | ±5V to ±20V or +5V to +30V - provides flexibility in mixed-signal systems with varying rail constraints |
Pinout & Package
MAX309EPE+ is housed in a 16-pin plastic DIP package (0.300" wide), RoHS-compliant and lead-free. Pin functions are validated per Maxim's official pin configuration diagram for MAX309 (DIP/SO/TSSOP).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0, A1 | Address Inputs | Select one of four differential channel pairs (00→CH1, 01→CH2, 10→CH3, 11→CH4); TTL/CMOS compatible |
| EN | Enable Input | Active-high control: disables all switches when low, reducing system power and crosstalk |
| NO1A–NO4A, NO1B–NO4B | Analog Inputs | Bidirectional terminals for differential input pairs; support rail-to-rail signal swing |
| COMA, COMB | Analog Outputs | Independent differential output nodes - allow simultaneous routing of two differential signals |
| V+, V− | Supply Rails | Support bipolar (±5V to ±20V) or single-ended (+5V to +30V) operation; substrate tied to V+ |
| GND | Reference Node | Logic ground reference; separate from analog signal return to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Operates with input signals spanning full V− to V+ range - eliminates need for level-shifting in ±15V systems |
| Guaranteed on-resistance flatness | ≤7Ω variation over ±10V analog range - preserves linearity in precision instrumentation amplifiers |
| Plug-in upgrade for DG409/DG509A | Pin- and function-compatible replacement - enables drop-in performance improvement without PCB redesign |
| Low power consumption | <300µW typical - suitable for portable and battery-powered test equipment with thermal constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX309ESE+ | Same die, 16-pin narrow SO package - 5.3mm width vs. DIP's 7.62mm; identical electrical specs and temp range (−40°C to +85°C) | Suitable for space-constrained PCBs; requires reflow soldering instead of through-hole assembly | Select for surface-mount production or higher board density; no change to schematic or firmware |
| ADG409BRZ | 4-channel differential mux with 85Ω RON (typ), 20nA leakage at +85°C, and no guaranteed on-resistance matching spec | Lower cost option where channel matching is not critical; lacks guaranteed flatness and charge injection specs | Choose when budget is primary constraint and precision matching is unnecessary; verify leakage impact in high-Z paths |
Compared with MAX309EPE+, MAX309ESE+ offers identical performance in a smaller footprint but requires SMT assembly, while ADG409BRZ trades guaranteed matching and low leakage for lower unit cost - making it viable only in non-critical signal routing.

FAQ
What is the operating temperature range of the MAX309EPE+?
The MAX309EPE+ is rated for operation from −40°C to +85°C. This extended industrial temperature range is confirmed in Maxim's official ordering information table and supported by 100% testing of leakage parameters at +85°C. The device uses the same die as other MAX309E-grade variants (e.g., MAX309ESE+, MAX309EUE), ensuring consistent thermal performance across packages. All electrical specifications in the datasheet - including on-resistance, leakage, and switching times - are guaranteed across this full range.
Does the MAX309EPE+ support single-supply operation?
Yes, the MAX309EPE+ supports single-supply operation from +5V to +30V. When used in single-supply mode, V− must be connected to GND. The device maintains TTL/CMOS logic compatibility, rail-to-rail analog signal handling, and all key specifications (e.g., <100Ω RON, <10pC charge injection) under these conditions. Typical operating characteristics graphs in the datasheet explicitly include +5V, +10V, +15V, and +20V single-supply curves for on-resistance and charge injection.
Is the MAX309EPE+ pin-compatible with the DG409?
Yes, the MAX309EPE+ is a plug-in upgrade for the DG409, as explicitly stated in the "Features" section of the datasheet. Pin assignments, logic levels, supply configurations, and functional behavior (including EN polarity and address decoding) match the industry-standard DG409. No PCB layout changes or firmware modifications are required - users gain improved on-resistance matching (<5Ω vs. unspecified), lower charge injection (<10pC vs. ~25pC), and enhanced ESD protection (>2000V vs. ~200V) immediately upon replacement.
What is the maximum analog signal range supported by the MAX309EPE+?
The MAX309EPE+ supports an analog signal range of ±10V when operated with ±15V supplies, as verified in the "Electrical Characteristics" tables and Typical Operating Characteristics plots (TOC-01 and TOC-02). With ±20V supplies, the range extends to ±15V; with +12V single supply, it supports 0V to +10V. The device guarantees flat on-resistance (≤7Ω max variation) and low leakage only within the specified signal range - exceeding these limits may degrade linearity or increase distortion.
How does the MAX309EPE+ handle differential signal routing?
The MAX309EPE+ implements true differential 2-of-4 routing via two independent COM outputs (COMA and COMB) and two sets of four bidirectional analog inputs (NO1A–NO4A and NO1B–NO4B). Each address combination (A1,A0) selects one pair of complementary channels - e.g., A1A0=00 connects NO1A→COMA and NO1B→COMB - enabling simultaneous routing of two differential signals without crosstalk. This architecture is distinct from single-ended muxes like the MAX308 and is optimized for balanced signal paths in communications and guidance systems.
