DG2002EDL-T1-GE3

Overview

The DG2002EDL-T1-GE3 is a single-pole, double-throw (SPDT) analog switch fabricated with high-density CMOS technology. It operates on a single power rail from 1.8 V to 5.5 V and features a typical drain-source on-resistance of 6 Ω at 5 V supply. The device provides powered-off protection to prevent abnormal current flow during power-down conditions. Key electrical parameters include a maximum turn-on time of 32 ns and a maximum turn-off time of 26 ns across the full operating temperature range of -40 °C to +85 °C. It exhibits low charge injection of 1 pC and maintains an off-isolation of -78 dB at 1 MHz.

Feature Summary

• Integrated powered-off protection circuit prevents abnormal current flow from the COM pin to V+ during power-down.
• Control logic inputs tolerate voltages exceeding the positive supply rail up to 5.5 V.
• Break-before-make switching performance eliminates signal shoot-through between outputs.
• High electrostatic discharge (ESD) immunity rated at 7000 V via human body model.

Applications

• Battery-powered devices
• Instrumentation systems
• Medical equipment
• Low voltage data acquisition
• Consumer and computing applications
