Overview
The DG4157DL-T1-E3 is a single-channel SPDT analog switch manufactured by Vishay Siliconix. It utilizes high-density CMOS technology to achieve low on-resistance of 0.86 ohms at 4.5V supply. The device operates on a single supply voltage ranging from 1.65V to 5.5V, supporting signals up to V+. Key electrical parameters include a -3dB bandwidth of 152MHz, charge injection of -5pC, and leakage current of 3nA. Switching times are 32ns (Ton) and 28ns (Toff). It features a break-before-make switching characteristic and is available in the SC-70-6 package.
Feature Summary
- High-density CMOS construction for low power consumption and fast switching speeds
- Integrated power-down protection circuit preventing abnormal current flow between COM and V+
- Control logic inputs tolerate voltages exceeding the positive supply rail up to 5.5V
- Break-before-make switching action ensures signal integrity during channel transitions
Applications
- Smartphones and tablet devices
- Portable medical equipment
- Consumer electronics and computer peripherals
- Portable instrumentation systems
Procurement Notes
Verify the specific suffix against official documentation, as standard datasheets typically list the DG4157E variant. Confirm RoHS compliance status and ensure the SC-70-6 package matches design requirements. Cross-reference with authorized distributors to validate availability and authenticity before procurement.
Selection Notes
Select this component when low on-resistance and high bandwidth are critical for signal integrity. Ensure the control logic voltage levels align with the system's 1.8V threshold requirement. Verify that the single-channel SPDT configuration meets the multiplexing needs without requiring additional external components.
Part Context
This part belongs to the DG4157 series of high-performance analog switches designed for space-constrained applications. It shares architectural similarities with other Vishay Siliconix CMOS switches but distinguishes itself through its ultra-low on-resistance and compact SC-70-6 packaging suitable for dense PCB layouts.
Replacement Considerations
The DG4157EDL-T1-GE3 is a verified equivalent offering identical electrical specifications and pinout compatibility. Both variants utilize the same CMOS process and package type, ensuring direct interchangeability in existing designs without schematic modifications.
