DG444BDY-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG444BDY-T1-E3 is a monolithic quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±4.5 V to ±22 V or a single supply up to 25 V, and features TTL/CMOS-compatible logic inputs. The device provides an on-resistance of 80 Ω maximum at room temperature and 95 Ω across the full operating range of -40 °C to +85 °C. Dynamic performance includes a turn-on time of 300 ns maximum and a turn-off time of 200 ns maximum. Power consumption is low, with supply currents limited to 5 µA maximum. The component is housed in a 16-pin Narrow SOIC package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E3' confirms lead-free and RoHS compliance status as defined by Vishay standards. Confirm the '-T1' designation indicates reel packaging suitable for automated surface-mount assembly processes. Ensure the ordering information matches the required 16-pin Narrow SOIC physical dimensions for PCB layout compatibility.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST topology is required for signal routing within data acquisition or test equipment designs. The 80 Ω on-resistance specification supports general-purpose analog switching applications. Verify that the 30 mA continuous current rating meets the load requirements of the target circuit without exceeding thermal dissipation limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the DG444B/DG445B family of improved quad SPST CMOS analog switches. It serves as an upgrade to the original DG444 series, offering minimized charge injection specifically optimized for sample-and-hold circuits. The device utilizes a high-voltage silicon-gate process to ensure robust operation across varying supply voltages.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The DG444BDY-E3 is a tube-packaged equivalent of the same functional device. The DG445BDY-T1-E3 offers identical specifications but with inverted logic states for the switch activation.
