DG2730DN-T1-GE4

Analog Switches, Multiplexers, Demultiplexers Overview

The DG2730DN-T1-GE4 is a two-port USB 2.0 high-speed analog switch configured as a single DPDT circuit, designed for bidirectional signal routing in portable applications. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a maximum power supply current of 2 µA. The device achieves a -3 dB bandwidth of 900 MHz and maintains an on-resistance of up to 8 Ω at 3 V. Key dynamic parameters include a turn-on time of 30 ns, a turn-off time of 25 ns, and a bit-to-bit skew of 50 ps. Packaged in a miniQFN-10L (1.4 mm x 1.8 mm) footprint, it supports an operating temperature range from -40 °C to +85 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '-T1-GE4' to confirm the reel packaging format and lead-free nickel-palladium-gold termination. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability codes before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing for USB 2.0 high-speed data lines requiring bidirectional switching within a compact form factor. The wide supply voltage range accommodates both Li-ion battery systems and standard 5 V rails. Verify that the 8 Ω maximum on-resistance aligns with your signal integrity budget and that the miniQFN-10 package dimensions fit the available PCB real estate constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the Vishay Siliconix DG2730 series of high-speed analog switches. It is specifically engineered for portable electronics where space is limited and signal fidelity is critical. The product utilizes sub-micron CMOS technology to achieve low power consumption while maintaining high bandwidth performance suitable for modern digital interfaces.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct pin-compatible alternatives within the Vishay DG27xx family if sourcing issues arise. Ensure any substitute maintains the same miniQFN-10 package dimensions and electrical characteristics, particularly the 900 MHz bandwidth and 5.5 V ESD rating.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum voltage tolerance for the logic control pins?

The logic control pins (S and OE) can tolerate voltages above the positive supply rail (V+), which are clamped by internal diodes.

Does the device support dual supply operation?

No, the DG2730 is designed for single-supply operation only, with a specified range of 2.7 V to 5.5 V.

What is the typical charge injection value?

The typical charge injection is 3 pC, measured with a load capacitance of 1 nF and zero generator resistance.
