DG3157BDN-T1-E4

Overview

The DG3157BDN-T1-E4 is a single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and features a 300 MHz -3 dB bandwidth. The device utilizes sub-micro CMOS technology to achieve low on-resistance and minimal propagation delay, making it suitable for both analog and digital signal switching. It includes power-down protection and break-before-make switching capabilities. The component is housed in an ultra-small miniQFN-6 package measuring 1 mm x 1.2 mm.

Feature Summary

Supports high-speed signal routing with a 300 MHz bandwidth and negligible propagation delay.
Features power-down safe design to protect circuits during low-power states.
Provides break-before-make switching to prevent signal shorting during transitions.

Applications

Bus switching applications requiring high-speed data transfer
Signal multiplexing and demultiplexing in portable electronics
Analog and digital signal path selection in communication systems

Procurement Notes

Verify the specific ordering suffix DN-T1-E4 against official Vishay documentation to confirm the miniQFN-6 package and RoHS compliance status. Ensure that the absence of an internal pull-down resistor on the control pin S aligns with the system logic requirements, as this distinguishes the DG3157B variant from the DG3157A.

Selection Notes

Select this component when a compact SPDT switch is required for signals up to 300 MHz. The DG3157B variant is appropriate for designs where the control pin S does not require an internal pull-down resistor. Verify that the operating voltage range of 1.65 V to 5.5 V matches the system supply rails and that the miniQFN-6 footprint fits the PCB layout constraints.

Part Context

This part belongs to the DG3157A/B family of low-voltage, high-speed analog switches. The DG3157B differs from the DG3157A primarily by lacking an internal pull-down resistor on the select pin S. Both variants share identical electrical performance characteristics regarding bandwidth, on-resistance, and switching speeds within the specified temperature range.

Replacement Considerations

The DG3157ADN-T1-E4 is a direct functional substitute within the same package, differing only by the inclusion of an internal pull-down resistor on the control pin S. Other Vishay SPDT switches may serve as alternatives if package compatibility or specific electrical parameters like on-resistance differ significantly from these requirements.

FAQ

What is the primary difference between the DG3157A and DG3157B?

The DG3157B does not have an internal pull-down resistor on the control pin S, whereas the DG3157A includes one. All other electrical specifications remain identical.
