Product details
Overview
DG3538DB-T5-E1 from Vishay Siliconix is a dual SPST analog switch optimized for audio, video, and USB signal routing in portable electronics. It operates from 1.8 V to 5.5 V single supply, delivers 4 Ω on-resistance at 3 V, 360 MHz −3 dB bandwidth, 0.2 Ω channel-to-channel RON matching, and 1.6 V logic compatibility - enabling direct interface with low-voltage microcontrollers in space-constrained designs.
For engineers reviewing the DG3538DB-T5-E1 datasheet, DG3538DB-T5-E1 pinout, DG3538DB-T5-E1 application, or DG3538DB-T5-E1 equivalent, this page provides verified functional identity, MICRO FOOT® 8-bump package mapping, validated switching performance metrics, and real-world use context for high-fidelity signal path selection in battery-powered consumer devices.
Technical Context
The DG3538DB-T5-E1 implements two independent normally-closed (NC) analog switches controlled by complementary CMOS logic inputs. Its sub-micron process enables rail-to-rail analog signal swing (0 V to V+) and maintains <1.2 Ω RON flatness across the full analog range at 2.7–5.5 V supply.
It features 8 pF input capacitance, 27 pF channel-on capacitance, 39 ns max turn-off time at 4.2 V, and −78.5 dB off-isolation at 1 MHz - confirming suitability for high-speed, low-distortion switching in USB 1.1/2.0 data lines and stereo audio paths where crosstalk and charge injection (<1 pC) must be minimized.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DCUR | 3.3 Ω RON (2.7 V), 200 MHz bandwidth, 5-pin SC70 package | Lower bandwidth limits USB 2.0 support; smaller footprint but no NC configuration | Select when board space is critical and USB 2.0 is not required; verify logic polarity compatibility |
| Analog Devices ADG849YRMZ | 0.5 Ω RON (3 V), 165 MHz bandwidth, 3 mm × 3 mm LFCSP | Superior RON but lower bandwidth; SPDT architecture requires redesign for NC-only use | Prefer for ultra-low-loss audio paths where bandwidth ≤165 MHz suffices; re-evaluate PCB layout for SPDT pinout |
Compared with TS5A23157DCUR and ADG849YRMZ, the DG3538DB-T5-E1 uniquely combines NC topology, 360 MHz bandwidth, and MICRO FOOT® packaging - making it optimal for USB 2.0 and stereo audio switching where both high fidelity and compact size are mandatory.

FAQ
What is the logic polarity of DG3538DB-T5-E1 control inputs?
The DG3538DB-T5-E1 uses active-high logic: when IN1 or IN2 is driven HIGH (≥1.4 V at 2.7 V supply), the corresponding NC switch opens (disconnected). When the input is LOW (≤0.5 V), the NC path remains closed (connected). This behavior is confirmed in the truth table on page 3 of Vishay document 73320 and applies across the full −40 °C to +85 °C operating range.
Does DG3538DB-T5-E1 support rail-to-rail analog signal swing?
Yes, DG3538DB-T5-E1 supports full rail-to-rail analog signal swing from 0 V to V+, as explicitly stated in the DESCRIPTION section (page 1) and verified in the "Analog Signal Range" specification (0 V to V+ at all temperatures). This allows undistorted transmission of signals such as ±2 Vpp audio or USB D+/D− levels without clipping or compression.
What is the maximum continuous current rating per switch of DG3538DB-T5-E1?
The DG3538DB-T5-E1 supports ±100 mA continuous current per NO/NC/COM terminal, as specified in the Absolute Maximum Ratings table (page 3). This rating holds across the full −40 °C to +85 °C temperature range and enables reliable operation in headphone driver enable/disable and USB VBUS switching applications.
Is DG3538DB-T5-E1 compatible with 1.8 V logic systems?
Yes, DG3538DB-T5-E1 is fully 1.6 V logic compatible across its entire 1.8–5.5 V supply range, meaning it reliably interprets 1.8 V logic HIGH (≥1.4 V) and LOW (≤0.5 V) at V+ = 1.8 V. This is documented in the FEATURES list and confirmed in the VINH/VINL specifications under both 2.7 V and 4.2 V test conditions.
What package type does DG3538DB-T5-E1 use, and what does the "-E1" suffix indicate?
DG3538DB-T5-E1 uses the MICRO FOOT® 8-bump chip-scale package (3 mm × 3 mm, 0.5 mm pitch). The "-E1" suffix denotes lead (Pb)-free terminations using tin/silver/copper (SnAgCu) alloy, as defined in the DESCRIPTION section (page 1) and Package Information (page 9) of Vishay document 73320.
