Product details
Overview
DG9233EDY-GE3 from Vishay Siliconix is a dual normally-open (NO) monolithic CMOS 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 - enabling high-fidelity signal switching in ADC front ends and sample-and-hold circuits.
For engineers reviewing the DG9233EDY-GE3 datasheet, DG9233EDY-GE3 pinout, DG9233EDY-GE3 application, or DG9233EDY-GE3 equivalent, key selection criteria include guaranteed low leakage (<100 pA), break-before-make timing not applicable (NO/NO configuration), SOIC-8 package compatibility, and ESD tolerance (8 kV HBM / 1 kV CDM).
Technical Context
The DG9233EDY-GE3 implements two independent single-pole single-throw (SPST) switches with active-high digital control logic (logic "1" ≥ 2.4 V enables conduction). Each switch conducts bidirectionally with matched on-resistance (ΔRDS(on) ≤ 2 Ω) and flat on-resistance (≤6 Ω variation over 0–5 V analog range) under 5 V supply.
Its architecture minimizes signal distortion via ultra-low parasitic capacitance (CNO/NC(off) = 3.8 pF, CCOM(on) = 7.8 pF), fast switching (tON = 32 ns, tOFF = 10 ns at 5 V), and sub-nW static power consumption (I+ ≤ 1 μA), making it suitable for battery-powered and noise-sensitive measurement paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RDS(on)) | 17 Ω typ. at 5 V - ensures minimal voltage drop and gain error in precision analog paths |
| Charge injection | 1 pC max - reduces settling error and pedestal distortion in sample-and-hold and multiplexed ADC inputs |
| On-leakage current | 100 pA max at 25 °C - preserves accuracy in high-impedance sensor interfaces and integrator circuits |
| Supply voltage range | +2.7 V to +5.5 V - supports direct interfacing with 3.3 V and 5 V logic and mixed-supply systems |
| Switching time (tON/tOFF) | 32 ns / 10 ns at 5 V - enables high-speed channel scanning in data acquisition systems up to ~10 MHz |
| ESD tolerance | 8 kV HBM / 1 kV CDM - enhances robustness during board handling and system-level ESD events |
| Off-isolation (OIRR) | −80 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-signal monitoring |
Pinout & Package
Package: 8-pin narrow-body SOIC (JEDEC MS-012, 5.00 mm × 3.95 mm × 1.50 mm height), RoHS-compliant, lead (Pb)-free, tube packaging (500 units).
| 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 logic and switch driver; decoupling capacitor required |
| 3 (COM1) | Common analog terminal (Switch-1) | Bidirectional signal path for Switch-1; connects to load or ADC input |
| 4 (IN1) | Digital control input (Switch-1) | Active-high logic: ≥2.4 V enables Switch-1 (NO); ≤0.8 V disables |
| 5 (IN2) | Digital control input (Switch-2) | Active-high logic: ≥2.4 V enables Switch-2 (NO); ≤0.8 V disables |
| 6 (COM2) | Common analog terminal (Switch-2) | Bidirectional signal path for Switch-2; isolated from COM1 when both switches are off |
| 7 (GND) | Analog/digital ground reference | Single ground plane required; ties internal substrate and logic reference |
| 8 (NC2) | No-connect terminal | Internally unconnected - must be left floating or tied to GND |
Key Features
| Feature | Design Value |
|---|---|
| Dual SPST, normally open (NO) configuration | Ensures signal path is open-circuit by default - critical for fail-safe operation in medical sensors and safety-critical monitoring |
| 1 pC max charge injection | Minimizes voltage glitch on sampled nodes, enabling <16-bit accuracy in precision data acquisition without recalibration |
| 100 pA max on-leakage at 25 °C | Preserves DC integrity in high-Z transducer interfaces (e.g., pH electrodes, thermopiles) and long-time-constant filters |
| 3.8 pF off-capacitance / 7.8 pF on-capacitance | Reduces capacitive loading on driving sources and maintains bandwidth >100 MHz in RF-adjacent signal chains |
| 8 kV HBM ESD rating | Eliminates need for external ESD protection diodes in handheld test equipment and portable diagnostics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RDS(on) (35 Ω typ. at 5 V), higher charge injection (3 pC), SOIC-16 package | Requires PCB redesign due to different pin count and layout; suited for higher-voltage (±15 V) industrial systems | Select when ±15 V dual-supply operation is needed; avoid for low-leakage medical use |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ.), but higher leakage (500 pA), 10-lead MSOP package, no SOIC option | Not pin-compatible; requires re-layout; better for low-RDS(on) audio routing, not ultra-low-leakage sensing | Choose only if on-resistance <2 Ω is mandatory and leakage tolerance >500 pA is acceptable |
Compared with MAX4617ESE+ and ADG1419BRMZ, the DG9233EDY-GE3 uniquely balances ultra-low leakage (100 pA), ultra-low charge injection (1 pC), and SOIC-8 compatibility - making it the optimal choice for space-constrained, battery-operated medical and portable test equipment where signal fidelity and layout continuity are critical.

FAQ
What is the logic polarity of DG9233EDY-GE3 control inputs?
The DG9233EDY-GE3 uses active-high logic: a logic "1" (≥2.4 V) turns each switch ON (closes the NO path), and a logic "0" (≤0.8 V) turns it OFF (opens the path). This matches standard 3.3 V/5 V CMOS/TTL drivers without level-shifting. The DG9233EDY-GE3 truth table confirms both switches are normally open and require high-level enable signals.
Does DG9233EDY-GE3 support dual-supply operation (e.g., ±5 V)?
No, the DG9233EDY-GE3 is specified for single-supply operation only, with V+ ranging from +2.7 V to +5.5 V and GND as the sole reference. It does not support split supplies or negative voltages on any pin. Analog signals must stay within 0 V to V+, and exceeding V+ on IN, COM, NO, or NC pins triggers internal clamping diodes - limiting its use to unipolar signal ranges.
What is the maximum analog signal voltage range supported by DG9233EDY-GE3?
The DG9233EDY-GE3 supports analog signals from 0 V to V+ (e.g., 0–5 V when V+ = 5 V). Absolute maximum ratings allow signals up to (V+ + 0.3 V), but proper linear operation is guaranteed only within the 0 V to V+ range. Exceeding V+ risks forward-biasing internal ESD diodes and introducing nonlinearities or increased leakage - so the DG9233EDY-GE3 should be used strictly within its specified analog voltage window.
Is DG9233EDY-GE3 pin-compatible with DG9232EDY-GE3 or DG9234EDY-GE3?
Yes - all three variants (DG9232E, DG9233E, DG9234E) share identical SOIC-8 and MSOP-8 pinouts and package footprints. However, their switch configurations differ: DG9233EDY-GE3 is dual-NO, DG9232EDY-GE3 is dual-NC, and DG9234EDY-GE3 is break-before-make (NO/NC). Swapping them requires logic inversion or firmware changes; the DG9233EDY-GE3 cannot be substituted without verifying control signal polarity and sequencing requirements.
What thermal derating applies to DG9233EDY-GE3 in SOIC-8 package?
For the DG9233EDY-GE3 in SOIC-8, power dissipation must be derated above +70 °C ambient at 6.5 mW/°C. The absolute maximum power dissipation is 400 mW at +70 °C. At +85 °C, allowable power drops to 400 mW − (15 °C × 6.5 mW/°C) = 302.5 mW. This derating ensures junction temperature remains within safe limits; the DG9233EDY-GE3 datasheet specifies a maximum junction temperature of +125 °C.
