Product details
Overview
DG9263DQ-T1-E3 from Vishay Siliconix is a low-voltage dual SPST analog switch in MSOP-8 package, designed for bidirectional signal routing with 40 Ω on-resistance, 35 ns turn-on time, and ±20 mA continuous current handling. It operates from 2.7 V to 5 V supply and is optimized for battery-powered portable instrumentation and sample-and-hold circuits.
For engineers reviewing the DG9263DQ-T1-E3 datasheet, DG9263DQ-T1-E3 pinout, DG9263DQ-T1-E3 application, or DG9263DQ-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, 1 pC charge injection, 2000 V ESD protection (HBM), and compatibility with TTL/CMOS logic levels at 3 V and 5 V rails.
Technical Context
The DG9263DQ-T1-E3 implements two independent single-pole/single-throw CMOS switches fabricated on Vishay's BCD-15 process. Each channel supports rail-to-rail analog signal switching (0–3 V or 0–5 V) with symmetrical conduction and guaranteed break-before-make operation to prevent signal shorting during state transitions.
Control logic is active-high: logic "1" (≥2.4 V) enables the switch, while logic "0" (≤0.8 V) disables it. Input leakage remains ≤1 µA across –40 °C to +85 °C, and internal epitaxial layer prevents latch-up under normal operating conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct interface with 3.3 V and 5 V logic systems 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 high-speed multiplexing in data acquisition and communication systems. |
| Charge Injection | 1 pC - limits voltage glitch in sample-and-hold and ADC front-end applications. |
| Off-Leakage Current | ±5000 pA max at room temperature - preserves signal integrity in high-impedance sensor interfaces. |
| ESD Protection | >2000 V HBM - provides robust handling during board assembly and field operation. |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial and portable equipment environments. |
Pinout & Package
Package: MSOP-8 (JEDEC MO-187, variation AA/BA), 3.0 mm × 4.9 mm footprint, 0.65 mm pitch, exposed pad optional per design.

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) (60 Ω typ), slower tON (60 ns), same MSOP-8 package. | Less suitable for sub-100 ns settling applications; higher on-resistance increases gain error in precision gain stages. | Consider only if lower cost outweighs performance trade-offs in non-critical signal paths. |
| ADG721BRMZ | Lower RDS(on) (2.5 Ω typ), but narrower supply range (1.8–5.5 V), higher QINJ (3 pC). | Better for ultra-low-loss paths but less robust in charge-sensitive sample-and-hold; requires tighter supply regulation. | Prefer for high-accuracy DC-coupled systems where on-resistance dominates error budget. |
Compared with MAX4623EUA+ and ADG721BRMZ, the DG9263DQ-T1-E3 delivers balanced performance: lower on-resistance than MAX4623EUA+, lower charge injection than ADG721BRMZ, and guaranteed break-before-make timing not specified for either alternative-making it optimal for mixed-signal systems demanding reliability and precision.

FAQ
What is the logic polarity of DG9263DQ-T1-E3 control inputs?
The DG9263DQ-T1-E3 uses active-high logic: a logic "1" (≥2.4 V) turns the switch ON, and a logic "0" (≤0.8 V) turns it OFF. This differs from the DG9262 variant, which is active-low. The truth table for DG9263DQ-T1-E3 is explicitly defined in Vishay Document 70862, Rev. D, page 1.
Does DG9263DQ-T1-E3 support rail-to-rail analog signal switching?
Yes, DG9263DQ-T1-E3 supports rail-to-rail analog signal switching from 0 V to V+, with full functionality verified at both 3 V and 5 V supplies. The analog signal range (VANALOG) is specified as 0–3 V at V+ = 3 V and 0–5 V at V+ = 5 V per the datasheet Section "Specifications (V+ = 3 V)" and "Specifications (V+ = 5 V)".
Is DG9263DQ-T1-E3 pin-compatible with DG9262 variants?
No, DG9263DQ-T1-E3 is not pin-compatible with DG9262 variants due to reversed logic polarity and different terminal labeling (NO vs NC). While both share the same MSOP-8 pinout layout, the functional assignment of pins 1 and 8 differs: DG9263DQ-T1-E3 uses NO1 and NO2, whereas DG9262 uses NC1 and NC2. Swapping them without redesign will cause incorrect switching behavior.
What is the maximum continuous current rating for DG9263DQ-T1-E3?
The DG9263DQ-T1-E3 has a maximum continuous current rating of ±20 mA per terminal, as stated in the Absolute Maximum Ratings table (Document 70862, page 2). Exceeding this limit risks thermal overstress or parametric shift, especially above 75 °C where derating to 6.5 mW/°C applies.
How does DG9263DQ-T1-E3 achieve latch-up immunity?
DG9263DQ-T1-E3 achieves latch-up immunity through an epitaxial layer structure in its BCD-15 process fabrication. This structural feature is explicitly cited in the "DESCRIPTION" section of Vishay Document 70862 and confirmed in the "Features" list, eliminating risk of destructive latch-up under normal operating conditions and transient overvoltage events.
