DG3257DN-T1-GE4

Overview

The DG3257DN-T1-GE4 is a single SPDT analog switch fabricated with high-density sub-micro CMOS technology. It operates on a single supply voltage ranging from 1.65 V to 5.5 V and achieves a typical on-resistance of 5 Ω at 4.2 V. The device provides a -3 dB bandwidth exceeding 700 MHz, ensuring minimal phase distortion for bidirectional signal flow. Key electrical parameters include a maximum turn-on time of 50 ns, a maximum turn-off time of 45 ns, and an input leakage current of 0.23 μA max. It features power-down protection, latch-up immunity of 300 mA per JESD78, and ESD tolerance exceeding 6 kV HBM.

Feature Summary

Ultra-small μDFN6L (1 mm x 1 mm) package designed for portable applications
High bandwidth exceeding 700 MHz with low parasitic capacitance
Direct interface capability with low-voltage MCUs via guaranteed 1.4 V logic threshold
On-chip fault protection including power-down protection and latch-up immunity

Applications

Smart phones
Tablet and e-readers
Camera and audio devices
Computer peripherals
Data storage systems
IoT devices
Wearable electronics
Portable healthcare equipment

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to ensure correct termination plating and packaging configuration. Confirm that the component meets RoHS compliance requirements and material categorization standards relevant to your manufacturing process. Ensure compatibility with standard reflow profiles as the nickel-palladium-gold terminations meet JEDEC standards.

Selection Notes

Select this component when a single-channel SPDT switch with high-speed performance under 1.65 V to 5.5 V operation is required. The device is suitable for applications needing direct MCU interfacing due to its TTL/CMOS compatible logic thresholds. Consider the ultra-small footprint if board space is constrained in portable or wearable designs requiring low charge injection and high isolation.

Part Context

The DG3257 belongs to the Vishay Siliconix DG series of enhanced analog switch ICs. This series focuses on providing increased operating voltage ranges, improved leakage limits, and lower switch-on resistance compared to previous generations. The DG3257 specifically targets high-bandwidth applications within the single-supply domain, utilizing advanced sub-micro CMOS processes to minimize parasitic effects.
