Overview
The DG469EQ-T1-E3 is a high voltage single-pole double-throw (SPDT) analog switch manufactured by Vishay Siliconix. It operates with dual supplies ranging from ±4.5 V to ±15 V or a single supply up to 12 V, supporting an analog signal range of ±15 V. The device features a maximum on-resistance of 6 Ω and a typical on-resistance flatness of 0.4 Ω. Switching speeds include a maximum turn-on time of 166 ns and a maximum turn-off time of 108 ns at ±15 V. It is housed in an 8-pin MSOP package and functions within a temperature range of -40 °C to +125 °C.
Feature Summary
- Break-before-make switching action prevents momentary shorting during channel transitions.
- TTL/CMOS compatible digital inputs ensure low voltage logic compatibility.
- High voltage capability supports analog signal ranges extending to the supply rails.
Applications
- Audio and video signal switching
- Precision automatic test equipment
- Relay replacement
- Communications systems
Procurement Notes
Verify the component against the official Vishay datasheet document number 71470 to confirm specifications. Ensure the MSOP-8 package matches the design requirements. Check for RoHS compliance status as indicated in the manufacturer documentation before finalizing procurement.
Selection Notes
Select this component when a single SPDT configuration with high voltage tolerance is required. The absence of an enable pin distinguishes it from the DG470 variant. Verify that the 6 Ω maximum on-resistance meets the circuit's power dissipation and signal integrity constraints.
Part Context
This part belongs to the DG469/DG470 family of high voltage analog switches. While functionally identical to the DG470, the DG469 lacks the enable input feature. Both devices share similar electrical characteristics and are designed for applications requiring robust signal routing across wide voltage ranges.
Replacement Considerations
Public confirmed substitute: MAX4660EUA+ from Analog Devices Inc./Maxim Integrated.
FAQ
Does the DG469EQ-T1-E3 have an enable pin?
No, the DG469 does not have an enable pin. The DG470 variant provides an enable input for high impedance mode control.
What is the maximum analog signal range?
The device supports an analog signal range of ±15 V when operated with dual supplies.
Is break-before-make switching guaranteed?
Yes, the datasheet guarantees break-before-make switching action to prevent momentary shorting between channels.
