DG9262DY-T1-E3

Overview

The DG9262DY-T1-E3 is a low-voltage dual single-pole/single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates on a single supply voltage ranging from 2.7 V to 12 V and supports an analog signal range of 0 V to the supply rail. The device features a maximum drain-source on-resistance of 40 Ω at 5 V, with turn-on and turn-off times of 35 ns and 20 ns respectively. It provides high off-isolation of -74 dB and low charge injection of 1 pC typical. The component is housed in an SOIC-8 package and functions within a temperature range of -40 °C to +85 °C.

Feature Summary

• Low power consumption suitable for battery-operated systems
• TTL/CMOS compatible logic interface
• High accuracy with low on-resistance and fast switching speeds
• Break-before-make timing guaranteed to prevent signal shorting

Applications

• Battery operated systems
• Portable test equipment
• Sample and hold circuits
• Cellular phones
• Communication systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and RoHS compliance status. Confirm that the SOIC-8 package dimensions match the target PCB footprint requirements. Check for any recent product change notices regarding manufacturing location or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when designing portable electronics requiring efficient board space utilization and low power dissipation. Ensure the application voltage stays within the 2.7 V to 12 V range. Verify that the required switching speed and leakage current specifications align with the device's performance characteristics under the intended operating temperature conditions.

Part Context

This part belongs to the DG926x family of low-voltage analog switches. It shares functional similarities with other Vishay devices like the DG9232 but offers optimized performance for modern portable applications. The 'DY' suffix indicates the narrow-body SOIC-8 package, while 'E3' denotes lead-free termination compliant with RoHS directives.

Replacement Considerations

Direct replacements include the DG9263DY-T1-E3, which differs only in internal logic polarity (normally open vs normally closed). Other potential substitutes within the Vishay portfolio should be evaluated based on pin compatibility and electrical parameter matching.

FAQ

What is the break-before-make characteristic of the DG9262?

The DG9262 guarantees break-before-make timing, ensuring that one switch opens before the other closes. This prevents momentary shorting between channels during switching transitions.

How does the input voltage affect the analog signal range?

The analog signal range extends from ground (0 V) up to the positive supply voltage (V+). Therefore, the maximum allowable analog signal amplitude is directly dependent on the applied V+ level.

Is the DG9262 protected against latch-up?

Yes, the device is built on a CMOS process with an epitaxial layer that prevents latch-up, enhancing reliability in various operating conditions.
