Overview
The DG9461DY-T1-E3 is a low-voltage single-pole/double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates on a +2.7 V to +5 V supply and features a maximum on-resistance of 40 Ω at 5 V. The device provides fast switching with turn-on and turn-off times of 35 ns and 20 ns, respectively. It exhibits low leakage current (200 pA max) and minimal charge injection (1 pC). Built on BCD-15 CMOS technology, it includes ESD protection exceeding 2000 V and guarantees break-before-make operation. The component is housed in an SOIC-8 package.
Feature Summary
- Low voltage operation optimized for portable battery-powered systems
- High-speed switching with minimal charge injection for signal integrity
- TTL/CMOS compatible logic interface for simple integration
- Robust ESD protection and latchup prevention via epitaxial layer
Applications
- Battery operated systems
- Portable test equipment
- Sample and hold circuits
- Cellular phones
- Communication systems
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free RoHS compliance when sourcing replacements. Confirm the manufacturer's datasheet revision matches the design requirements. Ensure the SOIC-8 package footprint aligns with existing PCB layouts. Check for any recent product change notices regarding manufacturing locations or material updates.
Selection Notes
Select this component for applications requiring low power consumption and high accuracy in small form factors. The DG9461DY variant is suitable for designs needing surface-mount assembly in standard SOIC-8 footprints. Consider the 40 Ω on-resistance limit when designing for low-signal attenuation paths. Verify that the operating temperature range meets the environmental constraints of the target system.
Part Context
The DG9461 belongs to Vishay Siliconix's family of low-voltage analog switches designed for high-performance signal routing. It utilizes the company's proprietary BCD-15 process to achieve low resistance and fast switching speeds within a compact physical size. This series is widely used in consumer electronics and communication devices where board space and power efficiency are critical design parameters.

FAQ
Does the DG9461 support dual power supplies?
No, the DG9461 is designed for single-supply operation ranging from +2.7 V to +5 V.
What is the guaranteed behavior during switching transitions?
Break-before-make operation is guaranteed to prevent short circuits between the common terminal and both throw terminals.
How does the device handle input signals exceeding the supply voltage?
Signals on the COM, NO, or NC pins exceeding V+ will be clamped by internal diodes, requiring forward diode current limits to be observed.
