Product details
Overview
DG9263DY-T1 from Vishay Siliconix is a low-voltage dual SPST analog switch in SOIC-8 package, designed for bidirectional signal routing with 40 Ω on-resistance (RDS(on)), 35 ns turn-on time (tON), and 20 ns turn-off time (tOFF). It operates from 2.7 V to 5 V supply and supports ±20 mA continuous current, making it suitable for battery-powered portable instrumentation and cellular phone front-end switching.
For engineers reviewing the DG9263DY-T1 datasheet, DG9263DY-T1 pinout, DG9263DY-T1 application, or DG9263DY-T1 equivalent, key selection considerations include logic polarity (active-high control), break-before-make guarantee, 1 pC charge injection, 200 pA channel-on leakage, and SOIC-8 thermal derating (6.5 mW/°C above 75 °C).
Technical Context
The DG9263DY-T1 implements two independent single-pole/single-throw CMOS switches fabricated on Vishay's BCD-15 process, each with symmetrical conduction and blocking up to V+ level. Its active-high logic interface requires ≥2.4 V for "on" state and ≤0.8 V for "off", and internal epitaxial layer prevents latchup.
Break-before-make timing is guaranteed across -40 °C to +85 °C, and ESD protection exceeds 2000 V per Method 3015.7. Signal clamping diodes limit input voltages beyond V+ or GND, requiring external current limiting per datasheet Note a.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 40 Ω typical at V+ = 5 V - ensures minimal voltage drop and signal distortion in precision analog paths |
| tON/tOFF | 35 ns / 20 ns at V+ = 5 V - enables high-speed multiplexing in sample-and-hold and test equipment |
| QINJ | 1 pC typical - reduces settling error in high-impedance sampling nodes |
| ICOM(on) | 200 pA max - preserves accuracy in low-current sensor interfaces and medical front-ends |
| V+ Range | 2.7 V to 12 V - supports operation from single Li-ion cell (3.0–3.7 V) up to industrial 5 V rails |
| OIRR | -74 dB at 1 MHz - provides strong isolation between channels in RF and communication systems |
| CCOM(off) | 13 pF - minimizes capacitive coupling into sensitive analog inputs during off-state |
Pinout & Package
Package: SOIC-8 (JEDEC MS-012, 5.00 mm × 4.00 mm × 1.75 mm height), rated for 400 mW power dissipation at TA ≤ 75 °C with 6.5 mW/°C derating above.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Normally Open Switch 1 Terminal | Connects to COM1 only when IN1 = logic high; no internal connection when off |
| 2 (V+) | Positive Supply Rail | Primary power input; must be decoupled locally; supports 2.7–12 V operation |
| 3 (COM1) | Common Terminal 1 | Bidirectional analog path shared between NO1 and NC1; handles full signal range 0–V+ |
| 4 (IN1) | Digital Control Input 1 | Active-high logic input; ≥2.4 V turns NO1–COM1 and NC1–COM1 on/off per truth table |
| 5 (IN2) | Digital Control Input 2 | Independent active-high control for second switch pair (NO2/NC2/COM2) |
| 6 (COM2) | Common Terminal 2 | Second bidirectional analog node; electrically isolated from COM1 |
| 7 (GND) | Ground Reference | Analog and digital ground return; must be low-impedance and tied to system ground plane |
| 8 (NO2) | Normally Open Switch 2 Terminal | Second independent NO path; mirrors functionality of Pin 1 for dual-channel operation |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Prevents momentary shorting between NO and NC paths during switching transitions |
| TTL/CMOS-compatible logic | Accepts standard 3.3 V or 5 V logic levels without level-shifting circuitry |
| Halogen-free construction | Complies with IEC 61249-2-21; supports environmentally regulated industrial and telecom designs |
| RoHS-compliant packaging | Lead-free terminations per Directive 2002/95/EC; exempt Pb not used in this SOIC-8 variant |
| Low charge injection (1 pC) | Enables accurate sampling in 12-bit+ data acquisition systems without added correction circuitry |

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+ | SOIC-8, 3.5 Ω RDS(on) at 5 V but higher 10 µA I+; no break-before-make guarantee | Better on-resistance for low-voltage precision, but unsuitable where timing-controlled path separation is required | Select MAX4623EUA+ only if ultra-low RDS(on) outweighs need for guaranteed break-before-make |
| ADG721BRMZ | MSOP-8, 4 Ω RDS(on), 1.8–5.5 V supply, but 10 nA ICOM(on) - 50× higher than DG9263DY-T1 | Superior speed and on-resistance, yet higher leakage limits use in high-impedance sensor nodes | Choose ADG721BRMZ for high-speed digital I/O muxing; avoid in picoampere-level analog sensing |
Compared with MAX4623EUA+ and ADG721BRMZ, the DG9263DY-T1 delivers balanced performance for portable systems: moderate RDS(on) with exceptionally low leakage and guaranteed break-before-make-critical for robustness in battery-powered instrumentation where signal integrity and fault tolerance coexist.

FAQ
What is the logic polarity of DG9263DY-T1?
The DG9263DY-T1 uses active-high logic control: applying ≥2.4 V to IN1 or IN2 turns the corresponding switch ON (NO–COM path closed), while ≤0.8 V turns it OFF. This differs from the DG9262DY-T1, which has inverted logic (active-low). The DG9263DY-T1 truth table explicitly defines logic "1" = On, ensuring predictable interface with standard microcontroller GPIOs without inversion logic.
Does DG9263DY-T1 support rail-to-rail analog signals?
Yes, DG9263DY-T1 supports analog signals from 0 V to V+ (e.g., 0–5 V when V+ = 5 V), with guaranteed operation across the full range. Its CMOS architecture allows bidirectional conduction, and internal clamping diodes protect against overvoltage transients - though forward diode current must be externally limited per datasheet Note a to avoid damage.
What is the maximum allowable supply voltage for DG9263DY-T1?
The absolute maximum V+ rating for DG9263DY-T1 is +13 V, but operational specifications are guaranteed only from 2.7 V to 5 V per datasheet test conditions. At V+ = 12 V, RDS(on) increases significantly and leakage rises; sustained operation above 5 V is not recommended unless validated per application-specific stress testing.
Is DG9263DY-T1 pin-compatible with DG9262DY-T1?
No - although both share identical SOIC-8 pinout and package dimensions, DG9263DY-T1 and DG9262DY-T1 have opposite logic polarity: DG9263DY-T1 is active-high (logic "1" = ON), while DG9262DY-T1 is active-low (logic "0" = ON). Swapping them without logic inversion will invert switch behavior, potentially causing system malfunction.
What thermal derating applies to DG9263DY-T1 in SOIC-8 package?
DG9263DY-T1 in SOIC-8 has a power dissipation limit of 400 mW at TA ≤ 75 °C. Above 75 °C, power must be linearly derated at 6.5 mW/°C, reaching zero dissipation at 137 °C ambient. This derating is defined in Absolute Maximum Ratings and must be applied in thermally constrained PCB layouts or high-temperature environments.
