Product details
Overview
DG9232EDY-T1-GE3 from Vishay Siliconix is a dual normally-closed (NC) single-pole single-throw (SPST) analog switch IC designed for precision signal routing in low-voltage instrumentation and medical front-ends. It delivers 17 Ω typical on-resistance at 5 V, 1 pC charge injection, 100 pA max on-leakage at 25 °C, and operates from +2.7 V to +5.5 V - enabling high-fidelity switching in battery-powered ADC/DAC signal paths.
For engineers reviewing the DG9232EDY-T1-GE3 datasheet, DG9232EDY-T1-GE3 pinout, DG9232EDY-T1-GE3 application, or DG9232EDY-T1-GE3 equivalent, key selection criteria include guaranteed low leakage (<100 pA), break-before-make timing compatibility (per DG9234E variant), SOIC-8 package thermal derating (6.5 mW/°C above 70 °C), and ESD robustness (8 kV HBM).
Technical Context
The DG9232EDY-T1-GE3 integrates two independent CMOS SPST switches with complementary logic control: both switches are normally closed (NC), turning off when logic input ≥2.4 V and on when ≤0.8 V. Its monolithic silicon design minimizes parasitic capacitance (3.8 pF off, 7.8 pF on) and ensures symmetrical bidirectional conduction with rail-to-rail analog signal range (0 V to V+).
Switching performance is optimized for low-noise systems: tON = 32 ns and tOFF = 10 ns at V+ = 5 V enable fast settling in sample-and-hold and multiplexed data acquisition, while 1 nW typical power consumption supports ultra-low-power portable healthcare devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 17 Ω typ. at 5 V - enables <1 LSB error in 16-bit ADC interfaces with ≤1 kΩ source impedance |
| Charge injection | 1 pC max - limits voltage glitch to <1 mV on 1 nF hold capacitors in precision sample-and-hold circuits |
| On-leakage current | 100 pA max at 25 °C - preserves accuracy in high-impedance sensor front-ends (e.g., pH electrodes, thermopiles) |
| Supply range | +2.7 V to +5.5 V - supports direct interfacing with 3.3 V and 5 V microcontrollers without level shifters |
| ESD tolerance | 8 kV HBM, 1 kV CDM - meets IEC 61000-4-2 Level 3 for handheld medical instrument handling |
| Switching time | tON = 32 ns, tOFF = 10 ns at 5 V - allows >10 MSPS multiplexing in automated test equipment |
| Analog bandwidth | Off-isolation >80 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-sensor DAQ systems |
Pinout & Package
Package: 8-pin narrow-body SOIC (JEDEC MS-012, 5.00 mm × 3.95 mm × 1.50 mm). Thermal derating: 6.5 mW/°C above 70 °C; maximum power dissipation: 400 mW.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC1 | Normally closed terminal, Switch-1 | Connected to COM1 when logic input = 0; clamped to V+ if voltage exceeds V+ by >0.3 V |
| 2 - V+ | Positive supply rail | Accepts 2.7–5.5 V; powers internal logic and switch driver; must be bypassed with 0.1 μF ceramic capacitor |
| 3 - COM1 | Common terminal, Switch-1 | Signal path midpoint; bidirectional conduction; rated for ±20 mA continuous current |
| 4 - IN1 | Logic control input, Switch-1 | CMOS-compatible: logic 0 ≤0.8 V (switch ON), logic 1 ≥2.4 V (switch OFF) |
| 5 - IN2 | Logic control input, Switch-2 | Independent of IN1; identical logic thresholds; enables asynchronous dual-channel control |
| 6 - COM2 | Common terminal, Switch-2 | Electrically isolated from COM1; shares same V+ and GND reference |
| 7 - GND | Ground reference | Return path for supply and signal currents; requires low-impedance PCB connection |
| 8 - NC2 | Normally closed terminal, Switch-2 | Connected to COM2 when IN2 = 0; internal ESD diode clamping applies identically to NC1 |
Key Features
| Feature | Design Value |
|---|---|
| Dual NC SPST topology | Eliminates need for external pull-downs in fail-safe signal gating (e.g., disconnecting sensors during power-up) |
| Rail-to-rail analog range | Supports full 0 V to V+ signal swing - critical for unipolar biomedical waveforms (ECG, EEG) without clipping |
| Low on-resistance flatness | 6 Ω max variation across 1–3 V analog range at 5 V supply - maintains gain linearity in programmable-gain amplifier paths |
| Break-before-make timing | Guaranteed via internal logic in DG9234E variant; DG9232E uses simultaneous switching - verified in truth table |
| TTL/CMOS-compatible inputs | Operates directly with 3.3 V FPGA I/O or 5 V MCU GPIO without interface logic or resistive dividers |
Applications
| Medical Instrumentation | Data Acquisition Systems |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single SPST, 35 Ω RDS(on) at 5 V, 0.5 pC charge injection, SOIC-8 | Lower charge injection but higher on-resistance; no dual-channel integration | Select when single-switch precision outweighs channel count; requires two units for dual functionality |
| ADG702BRMZ-REEL7 | Dual SPST, 3.5 Ω RDS(on) at 3 V, 0.2 pC charge injection, 8-lead MSOP | Superior on-resistance and charge injection, but MSOP-8 requires re-layout; lower voltage rating (3.6 V max) | Prefer for ultra-low-distortion audio or RF sampling where 3.3 V operation suffices and board space permits MSOP |
Compared with MAX4617ESE+ and ADG702BRMZ-REEL7, the DG9232EDY-T1-GE3 offers optimal balance of dual-channel integration, 5 V compatibility, and medical-grade leakage performance in standard SOIC-8 - avoiding redesign while meeting stringent low-current accuracy requirements.

FAQ
What is the logic configuration of DG9232EDY-T1-GE3?
The DG9232EDY-T1-GE3 implements a dual normally-closed (NC) SPST configuration: both switches conduct when logic input is low (≤0.8 V) and open when high (≥2.4 V). This is confirmed in the truth table on page 2 of Vishay document 75165, distinguishing it from DG9233E (NO) and DG9234E (break-before-make).
Does DG9232EDY-T1-GE3 support 3.3 V logic control with a 5 V analog supply?
Yes - DG9232EDY-T1-GE3 accepts TTL/CMOS-compatible logic inputs (0.8 V low, 2.4 V high) independent of V+ voltage. With V+ = 5 V, IN1 and IN2 function correctly at 3.3 V logic levels, enabling direct interfacing with mixed-voltage systems without level-shifting circuitry.
What is the maximum analog signal voltage allowed at COM or NC pins?
The absolute maximum analog voltage at COM, NC, or NO pins is (V+ + 0.3 V), per Absolute Maximum Ratings on page 2 of the datasheet. For V+ = 5 V, this limits analog signals to ≤5.3 V - exceeding this risks forward-biasing internal clamping diodes and damaging the device.
How does DG9232EDY-T1-GE3 handle ESD events during PCB handling?
DG9232EDY-T1-GE3 is rated for 8 kV HBM and 1 kV CDM ESD per JEDEC standards. These values are validated per MIL-STD-883 method 3015 and ANSI/ESDA/JEDEC JS-002, making it suitable for assembly in Class 1B ESD-sensitive environments without additional protection circuitry.
Is DG9232EDY-T1-GE3 pin-compatible with other variants in the DG923x family?
Yes - all DG9232E, DG9233E, and DG9234E variants share identical 8-pin SOIC and MSOP footprints and pinouts. The DG9232EDY-T1-GE3 can be substituted with DG9233EDY-T1-GE3 or DG9234EDY-T1-GE3 on the same PCB, provided logic configuration and timing requirements align with system firmware.
