Product details
Overview
DG9232EDY-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 systems. 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 supply - enabling high-fidelity signal switching in ADC front ends and sample-and-hold circuits.
For engineers reviewing the DG9232EDY-GE3 datasheet, DG9232EDY-GE3 pinout, DG9232EDY-GE3 application, or DG9232EDY-GE3 equivalent, key selection criteria include its NC configuration, SOIC-8 package, sub-35 ns switching speed, and guaranteed leakage performance across -40 °C to +85 °C - critical for battery-powered and healthcare-grade signal path integrity.
Technical Context
The DG9232EDY-GE3 integrates two independent CMOS SPST switches with normally closed logic behavior: both switches conduct when control input is logic "0" (≤ 0.8 V) and block when logic "1" (≥ 2.4 V). Its monolithic silicon design minimizes parasitic capacitance (3.8 pF off, 7.8 pF on) and ensures symmetrical bidirectional conduction with <2 Ω RDS(on) matching between channels.
It features overvoltage-tolerant TTL/CMOS-compatible inputs, 8 kV HBM ESD protection, and latch-up immunity (>300 mA per JESD78), supporting robust operation in noisy industrial and portable test equipment environments without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 17 Ω typ. at V+ = 5 V - enables low insertion loss and minimal gain error in precision analog paths |
| Charge injection | 1 pC max - reduces voltage glitch and settling time in sample-and-hold and multiplexed ADC applications |
| Switch leakage (on-state) | 100 pA max at 25 °C - preserves DC accuracy in high-impedance sensor interfaces and medical front ends |
| Switching time (tON/tOFF) | 32 ns / 10 ns typ. at V+ = 5 V - supports >10 MHz multiplexing rates in data acquisition systems |
| Supply voltage range | +2.7 V to +5.5 V - compatible with 3.3 V and 5 V logic domains and battery-powered operation |
| ESD tolerance (HBM) | 8 kV - eliminates need for external ESD protection in handheld and field-deployable instruments |
| Package | SOIC-8 (narrow body, JEDEC MS-012) - industry-standard footprint with 1.27 mm pitch for automated assembly |
Pinout & Package
Package: 8-pin narrow-body SOIC (JEDEC MS-012), 4.90 mm × 3.90 mm × 1.75 mm height, lead (Pb)-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC1) | No-connect terminal | Internally unconnected; must be left floating or tied to GND per layout best practice |
| 2 (V+) | Positive supply rail | Accepts +2.7 V to +5.5 V; powers internal CMOS switch core and level-shifting logic |
| 3 (COM1) | Common terminal of Switch-1 | Bidirectional analog path; connects to signal source or load depending on routing topology |
| 4 (IN1) | Control input for Switch-1 | Logic "0" (≤ 0.8 V) closes Switch-1; logic "1" (≥ 2.4 V) opens it - matches standard TTL thresholds |
| 5 (IN2) | Control input for Switch-2 | Independent logic input; identical threshold behavior to IN1 for synchronized or separate control |
| 6 (COM2) | Common terminal of Switch-2 | Second independent analog path; electrically isolated from COM1 with >80 dB off-isolation |
| 7 (GND) | Analog/digital ground reference | Single ground connection for supply return and logic reference; requires low-impedance PCB plane |
| 8 (NC2) | No-connect terminal | Internally unconnected; no electrical function - avoid routing traces or vias to this pad |
Key Features
| Feature | Design Value |
|---|---|
| Dual normally-closed (NC) SPST configuration | Ensures fail-safe signal continuity during power-up or control loss - critical for safety-critical medical monitoring paths |
| 1 pC max charge injection | Minimizes transient voltage kick on sampling capacitors, reducing calibration drift in precision data converters |
| 100 pA max on-leakage at 25 °C | Maintains signal integrity in high-impedance pH sensors, thermopiles, and electrophysiology front ends |
| 3.8 pF off-capacitance, 7.8 pF on-capacitance | Enables >100 MHz bandwidth in RF-adjacent analog routing while limiting crosstalk in dense PCB layouts |
| 8 kV HBM ESD rating | Supports direct handling and board-level integration without additional ESD protection components |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Normally open (NO) configuration; 35 Ω RDS(on) at 5 V; 2.5 pC charge injection | Requires inverted logic drive; higher on-resistance increases gain error in precision gain-setting paths | Select when NC behavior is not required and higher charge injection is acceptable for non-metrology use cases |
| ADG721BRMZ-REEL7 | NC configuration; 4 Ω RDS(on) at 5 V; 0.2 pC charge injection; but only 1 kV HBM ESD rating | Superior analog performance but lacks industrial-grade ESD robustness for field-deployable equipment | Prefer for lab-grade instrumentation where ESD exposure is controlled; avoid in portable or factory-floor environments |
Compared with MAX4617ESE+ and ADG721BRMZ-REEL7, the DG9232EDY-GE3 uniquely balances NC fail-safe operation, 1 pC charge injection, and 8 kV HBM ESD in a cost-effective SOIC-8 package - making it optimal for medical and portable test gear where reliability and signal fidelity are co-constrained.

FAQ
What is the logic polarity of DG9232EDY-GE3 switch control?
The DG9232EDY-GE3 uses active-low logic: a logic "0" (≤ 0.8 V) closes both SPST switches (normally closed), and a logic "1" (≥ 2.4 V) opens them. This behavior is confirmed in the truth table on page 2 of Vishay document 75165 and applies identically to both IN1 and IN2 inputs of the DG9232EDY-GE3.
Does DG9232EDY-GE3 support dual-supply operation?
No, the DG9232EDY-GE3 is specified for single-supply operation only, with V+ ranging from +2.7 V to +5.5 V referenced to GND. It does not support split-rail or negative supply configurations; analog signals must remain within 0 V to V+ per the absolute maximum ratings and analog signal range specification.
What is the maximum allowable analog signal voltage range for DG9232EDY-GE3?
At V+ = 5 V, the DG9232EDY-GE3 supports an analog signal range of 0 V to 5 V (full rail-to-rail) on COM, NO, and NC terminals. Signals exceeding V+ + 0.3 V or going below -0.3 V relative to GND risk forward-biasing internal clamping diodes and violating absolute maximum ratings.
Is DG9232EDY-GE3 pin-compatible with DG9233EDY-GE3 or DG9234EDY-GE3?
Yes - all three variants (DG9232EDY-GE3, DG9233EDY-GE3, DG9234EDY-GE3) share identical SOIC-8 pinouts and package dimensions per Vishay's ordering information table. However, their switch configurations differ: DG9232EDY-GE3 is dual-NC, DG9233EDY-GE3 is dual-NO, and DG9234EDY-GE3 is break-before-make with mixed NO/NC behavior.
What thermal derating applies to DG9232EDY-GE3 in SOIC-8 package?
For the SOIC-8 package, DG9232EDY-GE3 requires derating above +70 °C ambient: power dissipation must be reduced by 6.5 mW per °C rise. At +85 °C, maximum allowable power drops to 302.5 mW (400 mW − [15 °C × 6.5 mW/°C]), as specified in the Absolute Maximum Ratings table on page 2 of the datasheet.
