DG3538DB-T5-E1

Overview

The DG3538DB-T5-E1 is a dual single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and features an on-resistance of 4 Ω with a -3 dB bandwidth of 360 MHz. The device utilizes a MICRO FOOT 8-bump chip scale package measuring 3 x 3 mm. Key electrical parameters include a maximum turn-on time of 46 ns at 2.7 V, a maximum turn-off time of 73 ns, and a power supply current of 1 µA. It supports full rail signal swing and includes ESD protection exceeding 2 kV.

Feature Summary

• Dual SPST configuration housed in a space-saving MICRO FOOT package
• High linearity achieved through low on-resistance flatness and channel matching
• Compatible with 1.6 V logic levels across the entire operating voltage range
• Low power consumption enabled by sub-micron high density process technology

Applications

• Cellular phones
• MP3 players
• Media players
• Modems
• Hard drives
• PCMCIA devices

Procurement Notes

Verify component authenticity by checking for the lead-free "-E1" suffix designation, which indicates tin/silver/copper termination. Confirm the specific ordering suffix matches the required tape and reel quantity. Ensure the package type corresponds to the 8-bump MICRO FOOT format. Validate RoHS compliance status against current environmental directives before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring dual analog switching within a constrained footprint. The 1.6 V logic compatibility allows direct interfacing with low-voltage microcontrollers without level shifting. Consider the 360 MHz bandwidth for high-frequency signal routing applications. Verify that the 4 Ω on-resistance meets the signal integrity requirements of the target application.

Part Context

This part belongs to the DG353x series, which includes the DG3537, DG3539, and DG3540. These devices share identical electrical characteristics but differ in internal switch configurations. The DG3538 specifically provides two SPDT switches, whereas other members offer SPST or different contact arrangements. All variants utilize the same MICRO FOOT packaging and operate within the same voltage range.
