Overview
Description
MAX4644EUT+T is a Maxim/Analog Devices quad analog switch/multiplexer device. It contains four independent switches that route analog signals, enabling flexible signal-path selection in instrumentation, data acquisition, ADC front-ends, and audio or test equipment. The part emphasizes low on-resistance, low leakage, fast switching, and good isolation to preserve signal integrity across a wide supply range. The EUT+T suffix denotes specific packaging and reel/temperature options; exact electrical specs (supply range, on-resistance, leakage, switching time) are found in the datasheet. Typical uses include ADC input routing, sensor signal paths, and configurable frontend signal routing in mixed-signal systems.
Features
Here are the typical features of MAX4644EUT+T (industrial/extended temp, tape-and-reel):
- Quad SPST analog switches (four independent channels)
- Break-before-make switching for signal isolation
- Low on-resistance and low leakage when on/off
- Wide single-supply operation (roughly 1.8V–5.5V)
- TTL/CMOS-compatible control inputs
- Off/3-state capability for each channel
- ESD protection and overvoltage protection on I/O
- Extended temperature range (industrial/extended temp)
- Packaging: compact 16-lead package; tape-and-reel option (+T)
- Suitable for high-density routing and audio/video/select signal paths

Pinout
- Pin count: 16 pins (16-pin package)
- Function: MAX4644EUT+T is a quad SPDT analog switch array (four independent single-pole, double-throw switches) used to route analog signals through four COM nodes to either the NO or NC contact. Control inputs select the switch positions; supports low on-resistance and small signal routing in analog paths.
