DG9234EDY-T1-GE3

Overview

The DG9234EDY-T1-GE3 is a monolithic CMOS dual SPST analog switch from Vishay Siliconix, housed in an 8-lead narrow-body SOIC package. It operates on a single +2.7 V to +5.5 V supply and features mixed logic compatibility with TTL and CMOS inputs. The device provides break-before-make switching timing where Switch-1 is normally open and Switch-2 is normally closed. Key electrical parameters include a typical drain-source on-resistance of 17 Ω at 5 V, maximum leakage current of 100 pA at room temperature, and charge injection of approximately 0.78 pC. Switching times are specified as 32 ns turn-on and 10 ns turn-off at 5 V.

Feature Summary

Low parasitic capacitance and minimal charge injection for precision signal integrity
High electrostatic discharge tolerance exceeding 8000 V (HBM) and 1000 V (CDM)
Overvoltage tolerant digital control inputs compatible with standard logic families
Break-before-make switching timing prevents signal path shorting during transitions

Applications

Automatic test equipment
Data acquisition systems
Medical and healthcare systems
Sample-and-hold circuits
Battery powered systems

Procurement Notes

Verify the specific ordering suffix 'EDY' confirms the 8-pin SOIC package and tape-and-reel packaging format. Confirm RoHS compliance status through official Vishay documentation or material categorization reports before finalizing procurement orders.

Selection Notes

Select this component when low voltage operation between 2.7 V and 5.5 V is required alongside high ESD protection. Ensure the mixed logic input levels match the system's control voltage thresholds. Verify that the 17 Ω on-resistance meets the application's signal loss requirements.

Part Context

This part belongs to the DG9232E/DG9233E/DG9234E family of dual SPST analog switches. While sharing identical core specifications, the DG9234E is distinguished by its unique mixed configuration: Switch-1 is normally open and Switch-2 is normally closed, unlike the other family members which share uniform states.
