Overview
The DG9252EN-T1-E4 is a multiplexer switch IC manufactured by Vishay / Siliconix, belonging to the DG9252 series. It features a 2 x 4:1 channel configuration housed in a QFN-16 surface-mount package. The device operates on a single supply voltage ranging from 2.7 V to 16 V. Key electrical parameters include a maximum on-resistance of 252 Ohms, a bandwidth of 449 MHz, and typical off-isolation of -90 dB. Switching performance is characterized by a maximum turn-on time of 455 ns and a maximum turn-off time of 136 ns. The component supports an operating temperature range from -40°C to +125°C with a power dissipation rating of 525 mW.
Feature Summary
- Dual 4-to-1 multiplexer architecture for signal routing
- Wide single-supply voltage operation capability
- High bandwidth performance for signal integrity
- Extended industrial temperature range support
Applications
- Signal multiplexing in data acquisition systems
- Audio signal routing applications

Procurement Notes
This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted, with some sources indicating non-sale status in certain regions. Verification of current stock levels and alternative sourcing channels is required before procurement planning. Compliance documentation such as RoHS details should be confirmed via official datasheets.
Selection Notes
Designers should consider the high on-resistance value when selecting this part for low-voltage or precision analog signals. The wide supply voltage range offers flexibility but requires careful biasing. Due to the EOL status, long-term production viability is limited. Evaluate thermal management requirements given the 525 mW power dissipation limit in the QFN-16 package.
Part Context
The DG9252EN-T1-E4 is part of the DG925x family of multiplexer switches from Vishay / Siliconix. This series focuses on providing multi-channel switching solutions in compact surface-mount packages. The EN suffix denotes the specific QFN-16 package variant, while the T1 indicates reel packaging and E4 signifies lead-free compliance within the product line.
Replacement Considerations
Official documentation lists DG40 as a recommended alternative. Designers should verify pin compatibility and electrical parameter alignment when considering substitute components from other manufacturers or different series within the same product family.
