Product details
Overview
MAX4636ETB+T from Maxim Integrated is a dual 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 enables low-distortion audio/video routing and battery-powered multiplexing in space-constrained designs.
For engineers reviewing the MAX4636ETB+T datasheet, MAX4636ETB+T pinout, MAX4636ETB+T application, or MAX4636ETB+T equivalent, key selection criteria include guaranteed on-resistance flatness (≤1Ω), break-before-make timing (≤1ns), THD (0.1%), off-isolation (−65dB at 1MHz), and logic-level tolerance up to +5.5V independent of V+.
Technical Context
The MAX4636ETB+T implements two independently controlled SPDT switches using CMOS process technology, supporting bidirectional analog signal routing across the full supply rail range. Its logic inputs accept 0–5.5V levels regardless of V+, enabling direct interfacing with 5V logic while operating from +3.3V or +1.8V supplies.
Guaranteed break-before-make switching prevents momentary shorting between NO and NC paths. On-resistance matching between channels is ≤0.2Ω (max), and on-resistance flatness remains ≤1Ω over the entire analog signal range at +5V, ensuring minimal signal distortion in precision applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance | 4Ω max at +5V supply - enables high-current analog switching without significant voltage drop |
| On-Resistance Flatness | 1Ω max at +5V - ensures consistent gain/attenuation across full input signal range (0V to V+) |
| Turn-On / Turn-Off Time | 14ns / 6ns max - supports high-speed signal routing in communications and sampling systems |
| Rail-to-Rail Signal Range | 0V to V+ - allows full-swing analog signals without clipping in single-supply systems |
| THD | 0.1% - preserves audio fidelity and measurement accuracy in low-noise signal paths |
| Off-Isolation | −65dB at 1MHz - suppresses crosstalk between inactive channels in multi-channel routing |
| Supply Voltage Range | +1.8V to +5.5V - supports operation from Li-ion battery (3.0–3.7V) or regulated 3.3V/5V rails |
Pinout & Package
MAX4636ETB+T is housed in a 10-pin 3mm × 3mm thin QFN package (T1033-1) with no exposed pad. The package measures 3.00mm × 3.00mm × 0.80mm and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IN1 | Logic control input for Switch 1 | Active-high control: drives NO1→COM1 path when high; NC1→COM1 when low |
| 2 NO1 | Normally open terminal of Switch 1 | Connects to COM1 only when IN1 = high; isolated otherwise |
| 3 GND | Ground reference | Return path for supply current and logic reference; must be low-impedance |
| 4 NO2 | Normally open terminal of Switch 2 | Connects to COM2 only when IN2 = high; isolated otherwise |
| 5 IN2 | Logic control input for Switch 2 | Independent active-high control for second SPDT switch |
| 6 COM2 | Common terminal of Switch 2 | Signal I/O node shared between NO2 and NC2 paths |
| 7 NC2 | Normally closed terminal of Switch 2 | Connects to COM2 only when IN2 = low; isolated when high |
| 8 V+ | Positive supply input | Accepts +1.8V to +5.5V; powers analog and digital sections |
| 9 NC1 | Normally closed terminal of Switch 1 | Connects to COM1 only when IN1 = low; isolated when high |
| 10 COM1 | Common terminal of Switch 1 | Signal I/O node shared between NO1 and NC1 paths |
Key Features

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 |
|---|---|---|---|
| ADG736BRMZ-REEL | Higher on-resistance (6.5Ω typ at +5V), slower switching (25ns tON), but offers ±5V dual-supply capability | Suitable for industrial systems requiring bipolar signal handling, not rail-to-rail single-supply operation | Select ADG736BRMZ-REEL only if dual-supply operation or higher voltage tolerance (>+5.5V) is required |
| TS5A23157DCUR | Lower on-resistance (0.9Ω typ at +3.3V), but limited to +3.6V max supply and no guaranteed break-before-make | Better for ultra-low-RON 3.3V systems where timing control is less critical than conduction loss | Choose TS5A23157DCUR when minimizing on-resistance at 3.3V is prioritized over 1.8V operation or guaranteed BBM timing |
Compared with ADG736BRMZ-REEL and TS5A23157DCUR, MAX4636ETB+T uniquely combines 1.8V operation, guaranteed break-before-make, rail-to-rail performance, and 4Ω max RON in a 3×3mm QFN-making it optimal for compact, battery-powered, single-supply signal routing where timing integrity and wide supply flexibility are essential.

FAQ
What is the maximum supply voltage rating for MAX4636ETB+T?
The absolute maximum supply voltage (V+) for MAX4636ETB+T is +6V. However, the device is specified for reliable operation from +1.8V to +5.5V. Exceeding +6V risks permanent damage per Absolute Maximum Ratings. For sustained use, keep V+ ≤ +5.5V; the MAX4636ETB+T delivers its guaranteed 4Ω on-resistance and 14ns switching performance within this range.
Does MAX4636ETB+T support rail-to-rail analog signal operation?
Yes, MAX4636ETB+T supports true rail-to-rail analog signal handling: the analog signal range extends from GND to V+, with on-resistance flatness maintained at ≤1Ω across that full range when V+ = +5V. This allows undistorted passage of full-swing signals in single-supply systems without external biasing or level-shifting circuitry.
How does the logic polarity of MAX4636ETB+T differ from MAX4635ETB+T?
MAX4636ETB+T uses non-inverted logic: IN1/IN2 high connects NOx to COMx, and low connects NCx to COMx. In contrast, MAX4635ETB+T uses inverted logic (IN high → NCx, IN low → NOx). This functional difference means MAX4636ETB+T and MAX4635ETB+T are not interchangeable without adjusting control logic-both share identical electrical specs and pinout.
Can MAX4636ETB+T operate from a 1.8V supply while maintaining specified performance?
Yes, MAX4636ETB+T is fully specified down to +1.8V supply. At +1.8V, typical on-resistance is 100Ω and switching times are 56ns (tON) / 17ns (tOFF); these values are characterized and guaranteed over temperature. The device maintains rail-to-rail signal range, logic-level tolerance (inputs still accept up to +5.5V), and low leakage (<0.3nA), making it viable for ultra-low-power applications.
What is the thermal performance of the 3mm × 3mm thin QFN package used by MAX4636ETB+T?
The MAX4636ETB+T in the 10-pin thin QFN (3×3×0.8mm) has a thermal resistance θJA of 68.8°C/W and θJC of 12.5°C/W. At TA = +70°C, its continuous power dissipation is rated at 1951mW (derated above +70°C at 24.4mW/°C). This enables high-current analog switching without external heatsinking in compact PCB layouts where the MAX4636ETB+T operates within its safe operating area.
