Overview
The DG9234EDQ-T1-GE3 is a monolithic CMOS dual SPST analog switch from Vishay Siliconix. It operates on a single +2.7 V to +5.5 V supply and features a typical drain-source on-resistance of 17 Ω at 5 V, with a maximum of 35 Ω across the full temperature range. The device exhibits low charge injection of -0.78 pC and guaranteed off-leakage currents of 100 pA at room temperature. Switching times are specified as 32 ns for turn-on and 10 ns for turn-off at 5 V. It provides high ESD tolerance (8 kV HBM) and is housed in an 8-lead MSOP package.
Feature Summary
- Dual independent SPST switches with mixed logic states: one normally open and one normally closed channel.
- Low parasitic capacitance and minimal charge injection for precision signal integrity.
- High electrostatic discharge protection ratings for robust operation.
- Over-voltage tolerant inputs compatible with standard TTL and CMOS logic levels.
Applications
- Automatic test equipment
- Data acquisition systems
- Medical and healthcare systems
- Sample-and-hold circuits
Procurement Notes
Verify the specific ordering suffix 'T1' corresponds to tape and reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the requested quantity aligns with the minimum order requirements defined by the supplier's standard packaging specifications.
Selection Notes
Select this component for applications requiring mixed normally open and normally closed switching within a single package. The DG9234E is distinct from the DG9232E and DG9233E variants due to its unique internal logic configuration. Verify that the required on-resistance and leakage current specifications meet the system's precision requirements under the intended operating voltage conditions.
Part Context
This part belongs to the DG9232E family of low-voltage analog switches. While sharing similar electrical characteristics such as on-resistance and power consumption, the DG9234E is uniquely configured with one normally open and one normally closed switch. This distinguishes it from the DG9232E (dual NC) and DG9233E (dual NO) models.

FAQ
What is the specific logic configuration of the DG9234E compared to other family members?
Switch-1 is normally open and Switch-2 is normally closed. This differs from the DG9232E (both NC) and DG9233E (both NO).
Does the DG9234E support break-before-make switching timing?
Yes, the datasheet specifies that the DG9234E includes break-before-make switching timing between the two channels.
What is the maximum off-leakage current specification at room temperature?
The maximum off-leakage current is guaranteed at 100 pA at 25 °C.
