Product details
Overview
MAX4996LETG+ from Maxim Integrated is a triple DPDT analog switch IC designed for high-frequency signal routing in portable data interfaces. It operates from +2.5V to +5.5V, delivers 2.0Ω (typ) on-resistance, 6pF (typ) on-capacitance, and 670MHz -3dB bandwidth, enabling clean SDIO/UART/USB signal switching in space-constrained handheld devices.
For engineers reviewing the MAX4996LETG+ datasheet, MAX4996LETG+ pinout, MAX4996LETG+ application, or MAX4996LETG+ equivalent, this device is selected for low-leakage, rail-to-rail analog switching with active-low enable control and sub-1µA shutdown current in 24-pin TQFN packaging.
Technical Context
The MAX4996LETG+ implements six independently controllable analog switches grouped into three DPDT pairs, each steered by dedicated CB_ logic inputs (CB12, CB34, CB56). Its BiCMOS process enables simultaneous low RON flatness (±0.5Ω over 0–VCC) and minimal charge injection.
It features an active-low enable input (EN) that places all COM_ terminals in high-impedance state and reduces supply current to 0.1µA (max), supporting direct interfacing with low-voltage baseband processors without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.5V to +5.5V - supports single-supply operation across Li-ion battery voltage range and USB 5V rails |
| On-Resistance (RON) | 2.0Ω (typ) - minimizes signal attenuation and voltage drop in high-current analog paths |
| On-Capacitance (CON) | 6pF (typ) - preserves signal integrity up to 670MHz -3dB bandwidth for SD2.0/USB 1.1 signals |
| Shutdown Supply Current | 0.1µA (max) - enables ultra-low-power mode during interface idle periods |
| Off-Isolation | -60dB at 1MHz - prevents crosstalk between active and inactive signal paths in multiplexed interfaces |
| Operating Temperature | -40°C to +85°C - qualified for industrial and mobile end-equipment environments |
| Package | 24-pin TQFN (3.5mm × 3.5mm, exposed paddle) - provides thermal efficiency and PCB area savings |
Pinout & Package
MAX4996LETG+ uses a 24-pin thin quad flat no-lead (TQFN-EP) package with 3.5mm × 3.5mm footprint and thermally enhanced exposed paddle connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3 (CB12, CB34, CB56) | Digital control inputs | Select NO/NC connection state for respective switch pairs; TTL/CMOS compatible |
| 4–6, 16–18 (COM4–COM6, COM3–COM1) | Analog common terminals | Bidirectional signal path hubs; high-impedance when EN disabled |
| 7–12, 19–24 (NC6–NC1, NO1–NO6) | Normally closed / normally open terminals | Fixed analog I/O endpoints; support bidirectional signal routing without polarity constraints |
| 13 (GND) | Ground reference | Return path for analog and digital domains; connects to exposed paddle |
| 14 (VCC) | Positive supply | Single power rail for analog and logic; requires 0.1µF ceramic bypass near pin |
| 15 (EN) | Active-low enable | Disables all switches and drops ICC to ≤0.5µA; distinguishes MAX4996L from MAX4996 |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4996ETG+ | Active-high EN input; otherwise identical electrical specs and pinout | Requires inverted enable logic in host firmware/hardware | Select when system control logic drives enable high to activate switches |
| TMUX1574RSVR | Single-supply 1.8V–5.5V; 4.5Ω RON; 12-pin WQFN; no CB_ grouping | Supports individual switch control but lacks triple-DPDT pairing logic | Choose for lower pin count where per-channel granularity outweighs integrated pairing |
Compared with MAX4996ETG+, the MAX4996LETG+ simplifies enable logic integration in low-voltage baseband designs; versus TMUX1574RSVR, it offers tighter channel synchronization and optimized SDIO/USB routing architecture at the cost of higher pin count.

FAQ
What is the key functional difference between MAX4996LETG+ and MAX4996ETG+?
The MAX4996LETG+ features an active-low enable input (EN), whereas the MAX4996ETG+ uses an active-high enable input. All other electrical specifications-including on-resistance, capacitance, bandwidth, and pinout-are identical. This distinction affects how the host processor asserts enable control: MAX4996LETG+ activates when EN is pulled low, making it suitable for systems with open-drain or inverted logic outputs.
Does MAX4996LETG+ support bidirectional signal routing?
Yes, MAX4996LETG+ supports fully bidirectional analog signal routing. Its CMOS-based switches allow NO_, NC_, and COM_ terminals to function interchangeably as inputs or outputs without polarity restrictions. This enables flexible implementation in SDIO, USB, and UART paths where signal direction changes dynamically during operation.
What is the maximum analog signal voltage range supported by MAX4996LETG+?
The MAX4996LETG+ supports analog signals from 0V to VCC, covering the full rail-to-rail range. When powered from +2.5V to +5.5V, it handles analog inputs spanning 0V to the applied VCC voltage-enabling compatibility with 1.8V, 3.3V, and 5V logic families without external level-shifting circuitry.
How does the MAX4996LETG+ achieve low power consumption in shutdown mode?
The MAX4996LETG+ achieves ≤0.5µA shutdown current by disabling internal bias circuitry and placing all COM_ terminals in high-impedance state when EN is driven high. This design eliminates leakage paths through the analog channels and reduces quiescent current by over 99% compared to active operation, critical for battery longevity in portable devices.
Can MAX4996LETG+ be used for high-speed USB 2.0 signal switching?
No, MAX4996LETG+ is not suitable for USB 2.0 (480Mbps) signal switching. Its 670MHz -3dB bandwidth and 6pF on-capacitance are optimized for USB 1.1 (12Mbps) and SDIO (up to 50MHz), but insufficient for USB 2.0's 480MHz fundamental frequency and stringent impedance-matching requirements. Use dedicated USB 2.0 switches for that application.
