Overview
The DG9232EDY-GE3 is a monolithic CMOS dual SPST analog switch from Vishay Siliconix, housed in an 8-pin SOIC package. It operates on a single supply voltage ranging from +2.7 V to +5.5 V. The device features low on-resistance with a maximum of 65 Ω at 3 V and 35 Ω at 5 V across the full temperature range. Switching times are specified with a maximum turn-on time of 200 ns and turn-off time of 120 ns at 3 V. Charge injection is limited to 1 pC typical, while off-leakage current is guaranteed at 100 pA maximum at room temperature. Power consumption is typically 1 nW.
Feature Summary
- Dual independent single pole single throw (SPST) switches with normally closed configuration
- Low charge injection and leakage characteristics for precision signal switching
- High electrostatic discharge tolerance exceeding 8000 V (HBM) and 1000 V (CDM)
- Over-voltage tolerant inputs compatible with TTL and CMOS logic levels
Applications
- Automatic test equipment
- Process control and automation systems
- Data acquisition systems
- Medical and healthcare devices
- Sample-and-hold circuits
Procurement Notes
Verify the specific ordering suffix to confirm the tube packaging format associated with the GE3 designation. Confirm RoHS compliance status through official Vishay documentation prior to integration. Ensure the selected component matches the required operating temperature range specifications for the intended application environment.
Selection Notes
Select this component when a normally closed dual SPST configuration is required within a low voltage system. The device supports signals up to the positive supply rail. Consider the on-resistance flatness and matching requirements for the specific analog signal path. Verify that the input logic thresholds align with the available control voltage levels in the design.
Part Context
This part belongs to the DG9232E family, which includes variants with different default switch states such as the DG9233E and DG9234E. All members share identical pinouts and electrical characteristics but differ in their logic truth tables. The DG9232E specifically provides two normally closed channels, distinguishing it from the normally open or mixed configurations of its siblings.

FAQ
What is the default state of the switches for the DG9232E?
Both switches are normally closed when the logic input is low.
Can the DG9232EDY-GE3 handle signals exceeding the supply voltage?
Yes, the inputs are over-voltage tolerant, allowing signals up to the power supply level to be switched.
What is the maximum leakage current specification?
The off-leakage current is guaranteed to be a maximum of 100 pA at room temperature.
