Product details
Overview
DG9263DY from Vishay Siliconix is a dual single-pole/single-throw (SPST) analog switch IC designed for low-voltage signal routing in portable systems. It features 40 Ω on-resistance at 5 V, 35 ns turn-on time, 20 ns turn-off time, 1 pC charge injection, and operates from 2.7 V to 5 V supply. It is used in sample-and-hold circuits and battery-powered communication equipment.
For engineers reviewing the DG9263DY datasheet, DG9263DY pinout, DG9263DY application, or DG9263DY equivalent, this page delivers verified electrical parameters, SOIC-8 package details, truth table–driven logic behavior (active-high), and real-world selection guidance against comparable dual SPST switches.
Technical Context
The DG9263DY implements two independent CMOS transmission gates with break-before-make switching guaranteed across temperature. Its BCD-15 process enables low leakage (≤200 pA channel-on current) and latchup immunity via epitaxial isolation.
Logic control is TTL/CMOS-compatible with defined thresholds (0.8 V low, 2.4 V high), and analog signal range spans 0 to V+ - supporting rail-to-rail operation up to 5 V. ESD protection exceeds 2000 V per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct integration with 3.3 V and 5 V logic/system rails without level shifting |
| On-Resistance (RDS(on)) | 40 Ω max at V+ = 5 V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Turn-On / Turn-Off Time | 35 ns / 20 ns at V+ = 5 V - enables fast multiplexing in data acquisition and high-speed test equipment |
| Charge Injection | 1 pC typical - reduces settling error in sample-and-hold and ADC front-end applications |
| Channel-On Leakage | 200 pA max at 25 °C - preserves accuracy in high-impedance sensor interfaces and low-power standby modes |
| ESD Rating | >2000 V HBM - provides robust handling during PCB assembly and field operation |
| Analog Signal Range | 0 V to V+ - allows full rail-to-rail analog signal switching without clipping |
Pinout & Package
Package: SOIC-8 (Narrow Body, JEDEC MS-012), 4.90 mm × 3.90 mm footprint, 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Normally Open Terminal 1 | Switch output that connects to COM1 only when IN1 = logic high |
| 2 (V+) | Positive Supply Rail | Accepts 2.7 V to 5 V; powers internal CMOS switch core and level-shifting circuitry |
| 3 (COM1) | Common Terminal 1 | Input/output node shared between NO1 and NC1; bidirectional conduction path |
| 4 (IN1) | Control Input 1 | Active-high logic input (0.8 V low / 2.4 V high) enabling NO1–COM1 path |
| 5 (IN2) | Control Input 2 | Active-high logic input controlling NO2–COM2 path independently of IN1 |
| 6 (COM2) | Common Terminal 2 | Second bidirectional I/O node, isolated from COM1 and referenced to same V+/GND |
| 7 (GND) | Ground Reference | Return path for supply current and logic reference; must be low-impedance for noise control |
| 8 (NO2) | Normally Open Terminal 2 | Second switch output connecting to COM2 only when IN2 = logic high |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Operation | Functional down to 2.7 V supply - enables direct use with Li-ion battery discharge profiles (3.0–4.2 V) |
| Break-Before-Make Switching | Guaranteed timing separation between switch openings/closings - prevents momentary shorting in multiplexer configurations |
| TTL/CMOS-Compatible Inputs | 0.8 V low / 2.4 V high thresholds - eliminates need for external logic translators when interfacing with standard microcontrollers |
| Halogen-Free & RoHS-Compliant | Meets IEC 61249-2-21 and Directive 2002/95/EC - satisfies environmental compliance for global industrial and telecom deployments |
| Small SOIC-8 Footprint | 4.9 mm × 3.9 mm body - saves board space versus larger packages while maintaining hand-solderability and reflow compatibility |
Applications
| Portable Test Equipment | Sample-and-Hold Circuits |
|---|---|

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 |
|---|---|---|---|
| MAX4623EUA+ | Higher RDS(on) (65 Ω typ at 5 V), slower tON (60 ns), same SOIC-8 package | Lower bandwidth suitability; less ideal for >1 MSPS sampling rates | Select when cost sensitivity outweighs speed/on-resistance requirements |
| ADG721BRMZ | Lower leakage (10 pA typ), but higher RDS(on) (75 Ω min), 3 V–5.5 V supply | Better for ultra-low-current sensor buffering; worse for low-distortion audio routing | Prefer for femtoamp-level precision systems where on-resistance tolerance is relaxed |
Compared with MAX4623EUA+ and ADG721BRMZ, the DG9263DY delivers superior combination of speed (35 ns), on-resistance (40 Ω), and charge injection (1 pC) in a standard SOIC-8 - making it optimal for high-fidelity, battery-constrained signal routing where timing and linearity are critical.

FAQ
What is the logic polarity of DG9263DY?
The DG9263DY features active-high control logic: applying logic high (≥2.4 V) to IN1 or IN2 closes the corresponding NO–COM switch path, while logic low (≤0.8 V) opens it. This differs from the DG9262DY, which uses active-low logic - confirming DG9263DY's truth table is essential for correct MCU GPIO assignment. The DG9263DY's behavior is explicitly defined in its functional block diagram and truth table on page 2 of Vishay document 70862.
Does DG9263DY support rail-to-rail analog signals?
Yes, DG9263DY supports analog signals from 0 V to V+, meaning it handles rail-to-rail operation when V+ = 3.3 V or 5 V. This is confirmed in the "Analog Signal Range" specification (0 to V+ V) under both 3 V and 5 V test conditions in the datasheet. Signal integrity is preserved across this full range due to its CMOS transmission gate architecture and absence of body-diode conduction limitations.
What is the maximum operating temperature for DG9263DY?
The DG9263DY is rated for operation from -40 °C to +85 °C, as specified in the Ordering Information table and confirmed in the "Temp." column of all parametric tables (e.g., RDS(on), leakage, switching times). This industrial temperature grade applies to the DG9263DY-T1-E3 variant and is validated across all electrical parameters in the datasheet's D-suffix specifications.
Is DG9263DY pin-compatible with DG9262DY?
No, DG9263DY and DG9262DY are not pin-compatible. Although both use SOIC-8 and share identical pin numbering, their logic polarity differs: DG9263DY has active-high IN1/IN2 (NO closed on logic high), while DG9262DY has active-low control (NO closed on logic low). Swapping them without firmware changes causes inverted switching behavior. The pin functions (NO1, COM1, IN1, etc.) match, but logic interpretation does not.
What package variants are available for DG9263DY?
The DG9263DY is offered exclusively in SOIC-8 (narrow body, JEDEC MS-012). The MSOP-8 variant exists for the DG9263 family but carries the part number DG9263DQ-T1-E3 - not DG9263DY. The "Y" suffix in DG9263DY explicitly denotes SOIC-8 packaging, as documented in the Ordering Information table on page 2 of Vishay document 70862.
