Overview
The DG4051AEQ-T1-E3 is a CMOS analog multiplexer manufactured by Vishay Siliconix, housed in a 16-lead TSSOP surface-mount package. It functions as an 8:1 single-channel switch with a maximum on-resistance of 100 ohms and a channel-to-channel matching of 3 ohms. The device operates on a single supply voltage ranging from 2.7 V to 12 V or dual supplies from ±2.5 V to ±5 V. Key electrical characteristics include a -3 dB bandwidth of 330 MHz, charge injection of 0.25 pC, and leakage current of 1 nA. Switching times are specified at a maximum of 108 ns for turn-on and 92 ns for turn-off. The component supports an operating temperature range of -40°C to +125°C.
Feature Summary
- Provides high-speed signal routing with a 330 MHz bandwidth and low charge injection for precision applications.
- Features tight on-resistance matching between channels to ensure signal integrity across the multiplexed path.
- Operates within a wide temperature range suitable for industrial and commercial environments.
Applications
- Data acquisition systems requiring multi-channel signal selection.
- Programmable gain amplifiers and variable attenuation circuits.
- Signal routing in test and measurement equipment.
Procurement Notes
This specific part number is officially discontinued and no longer in production according to manufacturer documentation. Verification of availability should focus on identifying active replacement components or checking for surplus stock from authorized distributors. Designers must confirm that any substitute parts meet the original electrical specifications and pinout requirements before integration into existing hardware designs.
Selection Notes
Engineers selecting this component should note its discontinuation status and evaluate alternatives based on the 100-ohm on-resistance and 16-TSSOP form factor. The DG4051EEQ-T1-GE3 is listed as a related alternative within the same product family, offering similar functionality but potentially different electrical tolerances such as a lower on-resistance of 78 ohms. Compatibility checks regarding supply voltage ranges and switching speeds are essential when transitioning to successor parts.
Part Context
The DG4051AEQ-T1-E3 belongs to the DG405xA series of CMOS analog multiplexers produced by Vishay Siliconix. This series is designed for general-purpose analog switching applications where low distortion and fast switching are required. The 'E3' suffix indicates compliance with RoHS standards, while the 'T1' designation specifies the tape-and-reel packaging format for automated assembly processes.
Replacement Considerations
The DG4051EEQ-T1-GE3 is identified as a recommended alternative within the Vishay portfolio. Other potential substitutes may include variants from the DG4051E series or comparable devices from Nexperia, provided they match the 16-TSSOP package and 8:1 multiplexer configuration.
