Overview

Description

MAX4644EUT+T is a Maxim Analog Devices product: a quad-channel analog switch array used to route analog signals on a PCB. Key points:
- Four independent analog switches (silicon switches) controlled by digital inputs.
- Intended for signal routing, multiplexing, or switching in instrumentation, audio, or data-acquisition paths.
- Features typically include low on-resistance, low leakage, and break-before-make behavior.
- E suffix indicates extended temperature version; +T indicates Tape-and-Reel packaging.
Pinout, supply range, control logic, and exact electrical specs vary by variant. For precise numbers and layout, consult the MAX4644EUT+T datasheet. If you share a link or the exact datasheet, I can summarize the core specs (supply range, Ron, leakage, control pins, and timing) quickly.

Features

Here are the key features of MAX4644EUT+T (typical of this device family; variant specifics may vary):
- Quad analog switch array (4 channels) for routing multiple signals
- Single-supply operation with wide voltage range (2.7–5.5 V typical; extended-temp variant)
- Rail-to-rail analog signal range
- Low on-resistance and low leakage
- Break-before-make switching to prevent signal contention
- TTL/CMOS-compatible digital control inputs
- Low charge injection and fast switching speed
- Extended operating temperature (-40°C to +85°C)
- ESD protection on pins
- Tape-and-reel packaging option (+T)
Note: exact electrical specs (RON, leakage, speed, input range) vary by exact variant; consult the datasheet for precise numbers.

Package

MAX4644EUT+T is in a 28‑lead QFN package (4×4 mm) with an exposed pad, delivered in Tape & Reel (the +T suffix).

Pinout
