Product details
Overview
MAX307MWI/PR+ from Maxim Integrated is a precision, monolithic, CMOS differential analog multiplexer with 2-of-8 channel configuration, operating on ±4.5V to ±20V or +5V to +30V supplies. It delivers <100Ω on-resistance (max), <5Ω channel-to-channel matching, <10pC charge injection, and <2.5nA NO off-leakage at +85°C - enabling high-fidelity signal routing in military-grade test equipment and guidance systems.
For engineers reviewing the MAX307MWI/PR+ datasheet, MAX307MWI/PR+ pinout, MAX307MWI/PR+ application, or MAX307MWI/PR+ equivalent, key selection criteria include guaranteed on-resistance flatness (≤7Ω), rail-to-rail analog signal handling (±15V), ESD protection >2000V, and compatibility with DG407/DG507A replacement requirements.
Technical Context
The MAX307MWI/PR+ implements a fully decoded CMOS switch architecture with three address inputs (A0–A2) and an active-high enable (EN), selecting one of eight differential pairs (NO1A/NO1B through NO8A/NO8B) to connect bidirectionally to COMA and COMB outputs. Its silicon-gate process ensures low charge injection and minimal leakage across -55°C to +125°C.
It supports unbalanced supply configurations (e.g., +24V/–5V), maintains TTL/CMOS logic compatibility, and guarantees break-before-make timing (≤40ns) and transition time <400ns over full temperature range - critical for sample-and-hold circuits and battery-operated avionics where signal integrity and power efficiency are co-constrained.
Key Specifications

FAQ
What is the maximum allowable supply voltage difference for MAX307MWI/PR+?
The MAX307MWI/PR+ specifies a maximum voltage difference of +44V between V+ and V−. This allows flexible configurations such as +24V/–5V or ±20V, provided the absolute ratings (V+ ≤ +44V, V− ≥ –0.3V) are not exceeded. Exceeding this differential risks permanent damage per the Absolute Maximum Ratings table.
Does MAX307MWI/PR+ support single-supply operation, and what is its minimum voltage?
Yes, MAX307MWI/PR+ supports single-supply operation from +5V to +30V, with V− tied to GND. The minimum valid single-supply voltage is +5V - confirmed in Revision 3 of the datasheet and validated across all temperature grades. Operation below +5V is not characterized or guaranteed.
What is the guaranteed on-resistance flatness specification for MAX307MWI/PR+ and why does it matter?
MAX307MWI/PR+ guarantees on-resistance flatness of ≤7Ω maximum across the full specified analog signal range (±15V). This means RON varies by no more than 7Ω as the input voltage sweeps from –15V to +15V - critical for maintaining consistent gain and linearity in precision instrumentation amplifier front-ends and automatic gain control loops.
Can MAX307MWI/PR+ replace DG407 in existing designs without layout changes?
Yes, MAX307MWI/PR+ is explicitly documented as a plug-in upgrade for DG407 and DG507A. It shares identical pinout, function, and electrical behavior - including address decoding, enable logic, and differential I/O structure - allowing direct substitution in legacy PDIP or SOIC footprints without PCB modification.
What is the maximum operating temperature range certified for MAX307MWI/PR+?
MAX307MWI/PR+ is certified for continuous operation from –55°C to +125°C, as indicated by the "M" grade suffix and confirmed in the Ordering Information table. This extended temperature range is validated per MIL-STD-883 methods and supports deployment in engine-mounted sensors, missile guidance sections, and space-qualified payloads.
