DG444BDN-T1-E4

Overview

The DG444BDN-T1-E4 is a monolithic quad SPST CMOS analog switch manufactured by Vishay Siliconix. It operates within a single supply range of 13 V to 36 V or dual supplies of ±7 V to ±22 V. The device features a typical on-resistance of 45 Ω with a maximum of 80 Ω at room temperature, and up to 95 Ω across the full operating temperature range. Switching speeds include a turn-on time of 300 ns maximum and a turn-off time of 200 ns maximum. It utilizes a 16-pin QFN (4 x 4 mm) package and supports an operating temperature range from -40 °C to +85 °C.

Feature Summary

High-speed switching action designed for low error signal transmission
Minimized charge injection suitable for precision sample-and-hold circuits
TTL and CMOS-compatible logic control interface

Applications

Data acquisition systems
Communication systems
Automatic test equipment
Medical instrumentation
Audio switching

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific lot traceability requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to soldering. Validate that the ordering suffix matches the required packaging format.

Selection Notes

Select this component when high-speed analog signal routing is required alongside low power consumption. Verify that the system voltage does not exceed the absolute maximum ratings of 44 V between supplies. Ensure the logic input levels align with the specified TTL/CMOS compatibility thresholds for reliable switching operation.

Part Context

This part belongs to the DG444B/DG445B series, which are upgraded versions of the original DG444/DG445 devices. The series utilizes a high-voltage silicon-gate process with an epitaxial layer to prevent latchup. The DG444B specifically provides normally open switches, whereas the DG445B offers normally closed configurations.

FAQ

What is the difference between the DG444B and DG445B?

The DG444B contains four normally open (NO) switches, while the DG445B contains four normally closed (NC) switches.

How does the device handle signals exceeding supply rails?

Signals on the source or drain pins exceeding V+ or V- will be clamped by internal diodes. The forward diode current must be limited to the maximum current ratings to prevent damage.
