Product details
Overview
DG9262DY-E3 from Vishay Siliconix is a low-voltage dual single-pole/single-throw (SPST) analog switch optimized for bidirectional signal routing in portable systems. It delivers 40 Ω on-resistance at 3 V, 35 ns turn-on time, and 200 pA channel-on leakage, operating from 2.7 V to 5 V supply. It is used in battery-powered test equipment for precision signal path selection.
For engineers reviewing the DG9262DY-E3 datasheet, DG9262DY-E3 pinout, DG9262DY-E3 application, or DG9262DY-E3 equivalent, key selection criteria include guaranteed break-before-make timing, ±20 mA continuous current rating, MSOP-8/SOIC-8 package compatibility, and 2000 V HBM ESD protection per Method 3015.7.
Technical Context
The DG9262DY-E3 implements two independent CMOS SPST switches fabricated on Vishay's BCD-15 process, with epitaxial latchup prevention and rail-to-rail analog signal handling (0–3 V or 0–5 V). Each switch supports symmetrical conduction and blocks up to V+ when off.
Its digital control interface accepts TTL/CMOS logic levels (0.8 V low, 2.4 V high), enabling direct connection to microcontrollers without level-shifting. Break-before-make timing is guaranteed across -40 °C to +85 °C, ensuring no signal shorting during state transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables operation from single Li-ion or 3.3 V/5 V system rails |
| RDS(on) | 40 Ω max at V+ = 3 V - minimizes signal attenuation and voltage drop in low-level analog paths |
| tON/tOFF | 35 ns / 20 ns - supports >10 MHz switching in sample-and-hold or multiplexing applications |
| Channel-On Leakage | 200 pA max - preserves accuracy in high-impedance sensor interfaces and precision ADC front-ends |
| Charge Injection | 1 pC - reduces settling error and glitch energy in switched-capacitor circuits |
| ESD Rating | >2000 V HBM - provides robust handling during board assembly and field operation |
| Off-Isolation | -74 dB at 1 MHz - ensures minimal crosstalk between active and inactive channels |

| 3 (COM1) | Common terminal, Switch 1 | Bidirectional analog I/O node; connects to load or signal source depending on configuration |
| 4 (IN1) | Control input, Switch 1 | Active-low logic: logic 0 = ON, logic 1 = OFF (DG9262 function) |
| 5 (IN2) | Control input, Switch 2 | Independent active-low enable for second SPST switch |
| 6 (COM2) | Common terminal, Switch 2 | Second independent bidirectional analog path; electrically isolated from COM1 |
| 7 (GND) | Ground reference | Analog and digital ground return; requires low-impedance connection to system ground plane |

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 |
|---|---|---|---|
| MAX4622ESE+ | Higher RDS(on) (75 Ω @ 3 V), slower tON (60 ns), same SOIC-8 package | Less suitable for high-speed sampling; better for general-purpose routing where speed is secondary | Select MAX4622ESE+ only if lower cost outweighs 25 ns speed penalty and 35 Ω higher on-resistance |
| ADG722BRMZ | Lower leakage (100 pA), but higher RDS(on) (65 Ω @ 3 V); operates down to 1.8 V supply | Better for ultra-low-power sub-2 V systems; less optimal for 3 V–5 V industrial signal chains | Choose ADG722BRMZ when supply voltage drops below 2.7 V or sub-100 pA leakage is mandatory |
Compared with DG9262DY-E3, MAX4622ESE+ trades speed and on-resistance for broader vendor support, while ADG722BRMZ extends low-voltage operation at the cost of higher conduction loss-making DG9262DY-E3 the balanced choice for 2.7–5 V, high-fidelity portable instrumentation.

FAQ
What is the maximum analog signal voltage supported by the DG9262DY-E3?
The DG9262DY-E3 supports analog signals from 0 V to V+, where V+ ranges from 2.7 V to 5 V. At V+ = 3 V, the full analog range is 0–3 V; at V+ = 5 V, it extends to 0–5 V. Signals exceeding V+ or going below GND are clamped by internal diodes, so input voltages must remain within -0.3 V to (V+ + 0.3 V) to avoid damage or excessive leakage.
Does the DG9262DY-E3 require external pull-up or pull-down resistors on its control inputs?
No, the DG9262DY-E3 does not require external pull-up or pull-down resistors. Its IN1 and IN2 inputs are TTL/CMOS-compatible with defined logic thresholds (≤0.8 V for logic 0, ≥2.4 V for logic 1) and draw only 1 µA input current. Direct connection to microcontroller GPIO pins is sufficient, provided drive strength meets minimum voltage swing requirements.
Is the DG9262DY-E3 pin-compatible with the DG9263DY-E3?
No, the DG9262DY-E3 is not pin-compatible with the DG9263DY-E3. While both share the same SOIC-8 package and pin count, their truth tables differ: DG9262DY-E3 activates switches with logic 0 (active-low), whereas DG9263DY-E3 activates with logic 1 (active-high). Pin functions for NC1/NO1 and NC2/NO2 are swapped between the two variants, requiring PCB redesign for substitution.
What thermal derating applies to the DG9262DY-E3 above 75 °C?
The DG9262DY-E3 requires thermal derating above 75 °C ambient: power dissipation must be reduced by 6.5 mW per °C rise. At 85 °C, maximum allowable power drops from 400 mW (at ≤75 °C) to 335 mW. This is critical in sealed enclosures or high-density layouts where junction temperature may exceed ambient by >10 °C.
Can the DG9262DY-E3 be used in audio signal routing applications?
Yes, the DG9262DY-E3 is suitable for line-level audio routing due to its low on-resistance (40 Ω), low charge injection (1 pC), and -74 dB off-isolation at 1 MHz. However, for high-fidelity headphone drivers or microphone preamp stages, verify THD+N performance in-system, as RDS(on) mismatch and capacitance may affect frequency response above 20 kHz.
