Overview

Description

TMUX1104DQAR is a quad analog switch/multiplexer from Texas Instruments (TMUX family). It contains four bilateral analog switches that can route one of multiple analog signals to a common path (or vice versa) under digital control. A small set of control lines selects which channel is active, enabling compact, low-cost signal routing in mixed-signal designs. The device runs from a single supply (typical 1.65–5.5 V) and is available in the DQAR package. Key benefits: low on-resistance, low leakage, fast switching, and the ability to multiplex several analog signals with minimal distortion. Typical uses include data-acquisition front ends, sensor arrays, audio routing, instrumentation, and battery-management circuits. For exact electrical characteristics (on-resistance, input/output ranges, leakage, charge injection) and package details, see the TI TMUX1104 datasheet.

Features

Here are the key features of TMUX1104DQAR:
- Four independent SPST analog switches in one package
- Single-supply operation (typical Vcc range ~1.65 V to 5.5 V)
- Break-before-make switching to avoid shorting signals
- Common control input to enable/disable all channels
- Low on-resistance when on and low OFF leakage for good isolation
- Rail-to-rail analog signal path within supply rails
- Fast switching suitable for multiplexing and routing
- Small 8-pin DQAR package
- Industrial temperature range (-40°C to 125°C) and ESD/over-voltage protection
- Low quiescent current in typical operation
Note: For exact electrical specs (Rds(on), leakage, enable thresholds, etc.), please refer to the datasheet.
