Product details
Overview
DG9262DY-T1-E3 from Vishay Siliconix is a low-voltage dual single-pole/single-throw (SPST) analog switch optimized for high-speed, low-power signal routing in portable electronics. 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. Its break-before-make switching behavior and ±20 mA continuous current rating make it suitable for battery-powered sample-and-hold circuits and cellular phone front-end signal selection.
For engineers reviewing the DG9262DY-T1-E3 datasheet, DG9262DY-T1-E3 pinout, DG9262DY-T1-E3 application, or DG9262DY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing, low charge injection (1 pC), SOIC-8 package compatibility, and TTL/CMOS logic interface with 0.8 V/2.4 V thresholds - all critical for precision analog multiplexing in space-constrained designs.
Technical Context
The DG9262DY-T1-E3 implements two independent SPST switches fabricated in Vishay's BCD-15 CMOS process, supporting bidirectional analog conduction with rail-to-rail signal handling up to V+. Each switch guarantees break-before-make operation, preventing momentary shorting during state transitions.
It features internal ESD protection exceeding 2000 V (HBM, Method 3015.7), an epitaxial latchup prevention layer, and operates across –40 °C to +85 °C. Logic control inputs accept standard TTL/CMOS levels (0.8 V low, 2.4 V high), enabling direct interfacing with microcontrollers without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports single-cell Li-ion and 3.3 V/5 V system rails without external regulators. |
| RDS(on) | 40 Ω max at V+ = 3 V - ensures minimal signal attenuation and distortion in audio and sensor signal paths. |
| tON/tOFF | 35 ns / 20 ns - enables fast sampling in data acquisition systems up to ~10 MHz effective switching rate. |
| Charge Injection | 1 pC - reduces voltage glitch in sample-and-hold and ADC input stages, preserving DC accuracy. |
| ICOM(on) | 200 pA max - minimizes error current in high-impedance sensor interfaces and precision instrumentation. |
| Off-Isolation | –74 dB at 1 MHz - provides strong channel-to-channel rejection in multi-channel analog multiplexers. |

Pinout & Package
Package: SOIC-8 (Narrow Body, JEDEC MS-012), 4.90 mm × 3.90 mm × 1.50 mm profile, RoHS-compliant lead finish.
| 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 power supply | Primary analog/digital supply rail; bypass with 0.1 µF ceramic capacitor close to pin. |
| 3 (COM1) | Common terminal, Switch 1 | Bidirectional analog path; connects to load or signal source depending on configuration. |
| 4 (IN1) | Logic control input, Switch 1 | Active-low control: logic "0" (≤0.8 V) turns switch ON; logic "1" (≥2.4 V) turns OFF. |
| 5 (IN2) | Logic control input, Switch 2 | Independent active-low control for second switch; synchronous or asynchronous operation supported. |
| 6 (COM2) | Common terminal, Switch 2 | Second independent analog path; electrically isolated from COM1 except through substrate. |
| 7 (GND) | Analog/digital ground reference | Single ground plane required; tie directly to system AGND with low-inductance connection. |

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. | Limited to lower-bandwidth industrial sensing; lacks guaranteed break-before-make. | Select when cost sensitivity outweighs speed and switching safety requirements. |
| ADG721BRMZ-REEL7 | Lower leakage (10 pA), but higher RDS(on) (60 Ω @ 3 V); requires 1.8–5.5 V supply. | Better for ultra-high-impedance pH or ion-selective electrodes; less suitable for RF front-end due to higher capacitance. | Choose for nanoscale leakage-critical applications where 20 ns slower switching is acceptable. |
Compared with MAX4622ESE+ and ADG721BRMZ-REEL7, the DG9262DY-T1-E3 uniquely combines guaranteed break-before-make timing, 35 ns speed, and 40 Ω on-resistance in SOIC-8 - making it optimal for portable test gear and cellular RF path selection where reliability and signal fidelity are co-prioritized.

FAQ
What is the maximum analog signal voltage range supported by the DG9262DY-T1-E3?
The DG9262DY-T1-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 - design must limit forward diode current to ±20 mA continuous per terminal to avoid damage.
Does the DG9262DY-T1-E3 require external pull-up or pull-down resistors on its control inputs?
No, the DG9262DY-T1-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 GPIOs operating at 3.3 V or 5 V is fully supported without additional biasing components.
Is the DG9262DY-T1-E3 pin-compatible with the DG9263DY-T1-E3?
No, the DG9262DY-T1-E3 and DG9263DY-T1-E3 are functionally complementary but not pin-compatible. The DG9262DY-T1-E3 uses active-low logic (logic "0" = ON), while the DG9263DY-T1-E3 uses active-high logic (logic "1" = ON). Their pinouts differ: DG9262 has NC1/NC2 terminals, whereas DG9263 has NO1/NO2 - requiring PCB layout changes for substitution.
What is the thermal derating behavior of the DG9262DY-T1-E3 above 75 °C?
The DG9262DY-T1-E3 must be derated at 6.5 mW/°C above 75 °C ambient temperature. Its SOIC-8 package has a rated power dissipation of 400 mW at ≤75 °C. For example, at 85 °C ambient, maximum allowable power drops to 400 mW – (10 °C × 6.5 mW/°C) = 335 mW. This applies regardless of whether power is dissipated in the analog path or digital control circuitry.
Can the DG9262DY-T1-E3 be used in AC-coupled signal paths with bipolar swing?
Yes, the DG9262DY-T1-E3 supports bidirectional analog conduction and blocks signals up to the power supply rails when off. For AC-coupled use with bipolar signals (e.g., ±1.5 V), ensure V+ ≥ |peak signal| + headroom (e.g., V+ = 3.3 V for ±1.5 V signals), and bias the COM/NO/NC nodes appropriately using external DC restoration or coupling capacitors - the device itself does not provide level-shifting capability.
