Overview
Description
DG444DY is a quad CMOS analog switch/multiplexer from the DG444 family. It provides four bilateral analog switches that can route four independent analog signals (or be used as a four-channel multiplexer/demultiplexer) under digital control. When the control inputs enable a channel, the signal path is low-impedance; when disabled, the path is high-impedance, with very low off-leakage.
Key points:
- Four analog switches in one package
- Control inputs driven by standard logic levels
- Break-before-make switching to avoid signal shorts
- Suitable for signal routing, multiplexing, crosspoint switching, instrumentation, and test equipment
Note: exact electrical specs (on-resistance, leakage, supply range, control pinout) depend on the specific revision and package (the “DY” suffix indicates a particular packaging variant). Check the datasheet for the precise figures and pinout for your part.
