Product details
Overview
MAX4636ETB+TG104 from Maxim Integrated is a dual single-pole/double-throw (SPDT) CMOS analog switch with 4Ω max on-resistance at +5V, 14ns max turn-on time, and rail-to-rail signal handling from +1.8V to +5.5V supply. It features independent channel control, guaranteed break-before-make switching, and low crosstalk (–67dB at 1MHz), making it suitable for audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4636ETB+TG104 datasheet, MAX4636ETB+TG104 pinout, MAX4636ETB+TG104 application, or MAX4636ETB+TG104 equivalent, key selection criteria include on-resistance flatness (≤1Ω at +5V), THD (0.1%), off-isolation (–65dB), and compatibility with 1.8V logic interfaces while operating from higher supply rails.
Technical Context
The MAX4636ETB+TG104 implements two independent SPDT switches in a single 10-pin thin QFN (3mm × 3mm) package, using CMOS process technology with 239 transistors. Its logic inputs accept up to +5.5V regardless of V+ level, enabling direct interfacing with 5V logic while powered from +3.3V or +1.8V supplies.
Each switch supports bidirectional rail-to-rail analog signals (GND to V+), with guaranteed on-resistance matching ≤0.2Ω between channels and charge injection ≤2pC at +5V. Break-before-make timing is guaranteed ≤1ns, preventing momentary shorting during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (max) | 4Ω at +5V supply - enables low-loss signal routing for precision analog paths |
| On-Resistance Flatness (max) | 1Ω at +5V - ensures minimal distortion across full signal range (GND to V+) |
| Turn-On Time (max) | 14ns - supports high-speed multiplexing in communications and sampling circuits |
| Off-Isolation (at 1MHz) | –65dB - suppresses coupling between inactive channels in multi-signal systems |
| Crosstalk (at 1MHz) | –67dB - maintains signal integrity when routing adjacent audio or sensor channels |
| Total Harmonic Distortion | 0.1% at 20Hz–20kHz - preserves fidelity in audio signal path applications |

Pinout & Package
MAX4636ETB+TG104 is housed in a 10-pin 3mm × 3mm thin QFN package without exposed pad (JEDEC MO229/WEEC, pkg code T1033-1). Package dimensions: 2.90–3.10mm × 2.90–3.10mm × 0.70–0.80mm height, lead pitch 0.40mm, lead length 0.20–0.40mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 8 V+ | Positive supply voltage | Accepts +1.8V to +5.5V; powers analog and digital sections; decoupling required |
| 9 NC1 | Normally closed terminal of Switch 1 | Connects to COM1 only when IN1 = low; isolated when IN1 = high |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4635ETB+ | Inverted logic control (low = NO_, high = NC_) vs. MAX4636ETB+TG104's non-inverted logic | Requires PCB-level logic inversion or firmware adaptation for drop-in replacement | Select MAX4635ETB+ only if system logic polarity matches its inverted control scheme |
| TMUX6212RUMR | Higher on-resistance (6.5Ω typ at +5V), no guaranteed break-before-make, 12-bit DAC-compatible leakage specs | Better suited for industrial DAC output switching than high-fidelity audio routing | Prefer MAX4636ETB+TG104 for audio/low-THD apps; TMUX6212RUMR for cost-sensitive industrial muxing |
Compared with MAX4635ETB+ and TMUX6212RUMR, MAX4636ETB+TG104 uniquely combines non-inverted logic, guaranteed break-before-make, and 0.1% THD-making it optimal for audio and precision sampling where timing integrity and signal purity are critical.

FAQ
What is the maximum supply voltage rating for MAX4636ETB+TG104?
The absolute maximum supply voltage (V+) for MAX4636ETB+TG104 is +6V. Operation above +5.5V is not recommended, as the device is specified and characterized for reliable performance from +1.8V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings.
Does MAX4636ETB+TG104 support rail-to-rail analog signals?
Yes, MAX4636ETB+TG104 supports true rail-to-rail analog signal handling - signals from GND to V+ pass through the switch with minimal on-resistance variation. This is confirmed by ≤1Ω on-resistance flatness over the full 0V to V+ range at +5V supply, enabling accurate DC-coupled signal routing.
Can MAX4636ETB+TG104 interface directly with 5V logic while powered from a 3.3V supply?
Yes, MAX4636ETB+TG104 logic inputs (IN1, IN2) tolerate up to +5.5V regardless of V+ level. When powered from +3.3V, the device accepts standard 5V TTL/CMOS logic levels without external level translation - a key feature verified in the Electrical Characteristics table under Digital I/O parameters.
What is the guaranteed break-before-make time for MAX4636ETB+TG104?
The break-before-make time for MAX4636ETB+TG104 is guaranteed ≤1ns across temperature and supply conditions. This specification ensures no overlap conduction between NO_ and NC_ terminals during switching, preventing momentary shorts in sensitive analog signal paths - explicitly stated in the Dynamic Characteristics section.
Is thermal performance affected by the lack of an exposed pad in the MAX4636ETB+TG104 QFN package?
Yes - unlike many QFN variants, MAX4636ETB+TG104 uses a thin QFN without an exposed thermal pad (per Package Information note: "The MAX4636 does not have an exposed pad"). Its thermal resistance θJA is 24.4°C/W (derating 24.4mW/°C above +70°C), limiting continuous power dissipation to 1951mW at +70°C ambient - a design constraint requiring careful layout and airflow consideration in high-density applications.
