DG612AEQ-T1-E3

Analog Switches, Multiplexers, Demultiplexers Overview

The DG612AEQ-T1-E3 is a quad single-pole single-throw (SPST) analog switch from the DG611A family, manufactured by Vishay Siliconix. It features four independently selectable switches with normally open logic control. The device operates on a single supply of 2.7 V to 12 V or dual supplies of ±2.7 V to ±5 V. Key electrical parameters include a maximum on-resistance of 115 Ω at ±5 V and a typical charge injection of 1 pC. Switching speeds are specified as 27 ns turn-on and 16 ns turn-off at ±5 V. The component is housed in a 16-lead TSSOP package and supports an operating temperature range from -40 °C to +125 °C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EQ corresponds to the 16-lead TSSOP package configuration required for the design. Confirm that the -E3 designation indicates compliance with RoHS directives and halogen-free standards as defined in the official Vishay documentation. Ensure the selected variant meets the necessary thermal and electrical specifications for the intended application environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally open SPST configuration is required within the DG611A series. Compare against DG611AEQ for normally closed switches and DG613AEQ for mixed configurations. Consider the TSSOP package dimensions and thermal resistance characteristics relative to available board space and heat dissipation requirements in the target system design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the DG611A, DG612A, and DG613A family, which improves upon the industry-standard DG611 series. The family integrates low-power CMOS drivers with high-speed DMOS FETs to achieve high speed, low power, and low on-resistance simultaneously. These devices are designed for high-speed switching applications requiring precision and low distortion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

DG611AEQ-T1-E3 serves as a functional alternative with different switch logic states. DG613AEQ-T1-E3 offers a mixed normally open/closed configuration. Verify pin compatibility and logic truth tables before substituting, as the internal switch states differ between these variants within the same package.
