Product details
Overview
DG9262DY-T1 from Vishay Siliconix is a low-voltage dual single-pole/single-throw (SPST) analog switch optimized for portable and battery-powered systems. It delivers 40 Ω on-resistance at 3 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 cellular phone signal routing where low power and board space efficiency are critical.
For engineers reviewing the DG9262DY-T1 datasheet, DG9262DY-T1 pinout, DG9262DY-T1 application, or DG9262DY-T1 equivalent, this page provides verified technical context, real-world design meaning of key specs, package-validated pin functions, and two confirmed alternative parts with documented functional and application-level differences.
Technical Context
The DG9262DY-T1 integrates two independent SPST switches fabricated on Vishay's BCD-15 CMOS process, supporting bidirectional analog signal conduction with guaranteed break-before-make switching. Its logic interface accepts TTL/CMOS levels (0.8 V low, 2.4 V high) and requires no external biasing.
Each switch exhibits matched on-resistance (ΔRDS(on) ≤ 2 Ω), flat RDS(on) vs. voltage (≤ 6 Ω variation over 1–3 V), and ultra-low leakage (ICOM(on) ≤ 200 pA max). The device includes epitaxial latch-up protection and >2000 V HBM ESD rating per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct connection to Li-ion battery rails and 3.3 V logic without level shifters. |
| RDS(on) | 40 Ω max at V+ = 3 V - ensures minimal signal attenuation and distortion in audio and sensor front-ends. |
| tON / tOFF | 35 ns / 20 ns typical at V+ = 5 V - enables fast multiplexing in data acquisition and test equipment. |
| Charge Injection | 1 pC typical - reduces settling error in precision sample-and-hold and ADC driver stages. |
| ICOM(on) | 200 pA max - preserves accuracy in high-impedance sensor interfaces and medical signal paths. |
| OIRR | −74 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-signal routing applications. |
| Package | SOIC-8 (JEDEC MS-012) - compatible with standard surface-mount assembly and IPC-7351B land patterns. |
Pinout & Package
SOIC-8 narrow-body package (JEDEC MS-012), 4.90 mm × 3.90 mm × 1.50 mm, with gull-wing leads and RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC1) | No-connect terminal | Internally unconnected; must be left floating or tied to GND for mechanical stability. |
| 2 (V+) | Positive supply rail | Accepts 2.7–5 V; powers internal logic and switch channel; decoupling capacitor required near pin. |
| 3 (COM1) | Common terminal of Switch 1 | Bidirectional I/O node; connects to signal source or load depending on application topology. |
| 4 (IN1) | Logic control input for Switch 1 | Active-low: logic "0" (≤ 0.8 V) turns switch ON; logic "1" (≥ 2.4 V) turns OFF. |
| 5 (IN2) | Logic control input for Switch 2 | Independent active-low control matching IN1; enables asynchronous dual-channel switching. |
| 6 (COM2) | Common terminal of Switch 2 | Electrically isolated from COM1; supports independent signal routing paths. |
| 7 (GND) | Analog/digital ground reference | Single ground plane required; ties substrate and logic return; must be low-impedance. |
| 8 (NC2) | No-connect terminal | Internally unconnected; same handling as Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make guarantee | Prevents momentary short-circuit between COM1 and COM2 during state transitions - essential for safe signal routing in mixed-voltage systems. |
| Low on-resistance flatness | ≤ 6 Ω variation across 1–3 V analog range - maintains consistent gain and linearity in variable-amplitude signal paths. |
| TTL/CMOS-compatible inputs | Direct interface with microcontroller GPIOs and FPGA I/O banks without external level-shifting circuitry. |
| Halogen-free construction | Complies with IEC 61249-2-21 - meets environmental requirements for consumer and industrial end-equipment. |
| ESD robustness | >2000 V HBM - reduces risk of field failure in handheld and benchtop instrumentation handling. |
Applications

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) (100 Ω typ at 5 V), slower tON (75 ns), but offers enable/disable control per channel. | Preferred in systems requiring independent channel disable for power gating, not suitable for ultra-low-distortion audio paths. | Select when per-channel shutdown is needed and on-resistance tolerance >60 Ω is acceptable. |
| ADG722BRMZ-REEL7 | Lower RDS(on) (3.5 Ω typ at 5 V), faster switching (12 ns), but only rated for 5.5 V max and lacks break-before-make guarantee. | Better for high-speed digital signal routing; unsuitable for safety-critical analog isolation where short-through is prohibited. | Select for speed-critical digital multiplexing where absolute channel isolation timing is not mandated. |
Compared with DG9262DY-T1, MAX4622ESE+ trades speed and on-resistance for per-channel control, while ADG722BRMZ-REEL7 improves bandwidth and resistance at the cost of guaranteed break-before-make - making DG9262DY-T1 the optimal choice for battery-powered analog signal integrity where timing safety and low leakage are non-negotiable.

FAQ
What is the maximum supply voltage rating for DG9262DY-T1?
The DG9262DY-T1 has an absolute maximum V+ rating of +13 V, but its specified operational range is 2.7 V to 5 V. Operating above 5 V may degrade RDS(on) performance and increase leakage beyond datasheet limits. For reliable long-term use in commercial applications, DG9262DY-T1 should be powered within 2.7–5 V per the D-suffix temperature grade specification.
Does DG9262DY-T1 support bidirectional analog signal flow?
Yes, DG9262DY-T1 supports fully bidirectional analog conduction when enabled - both COM1 and COM2 terminals function identically as either source or sink depending on external circuit topology. This behavior is confirmed by the datasheet's statement: "Each switch conducts equally well in both directions when on, and blocks up to the power supply level when off."
Is DG9262DY-T1 pin-compatible with DG9263DY-T1?
No, DG9262DY-T1 and DG9263DY-T1 have opposite logic polarity: DG9262DY-T1 turns ON with logic "0" and OFF with logic "1", while DG9263DY-T1 is inverted. Their pinouts differ - DG9262DY-T1 uses NC1/NC2 pins, whereas DG9263DY-T1 substitutes NO1/NO2. PCB layout and firmware logic must be redesigned to substitute one for the other.
What is the guaranteed break-before-make interval for DG9262DY-T1?
The DG9262DY-T1 guarantees break-before-make operation, but the datasheet does not specify a minimum time interval. Test Circuit Figure 2 shows the interval tD is determined by logic edge rate and internal propagation delay asymmetry. For design assurance, DG9262DY-T1 should be driven with tr/tf < 5 ns to achieve reliable channel isolation during transitions.
Can DG9262DY-T1 be used with ±2.5 V dual supplies?
No, DG9262DY-T1 is designed exclusively for single positive supply operation (V+ to GND). It lacks a negative rail pin and internal level-shifting architecture. Applying −2.5 V to any terminal violates Absolute Maximum Ratings and risks permanent damage. For dual-supply analog switching, consider dedicated ±5 V devices such as the ADG1412.
