DG309CY

Overview

The DG309CY is a quad, single-pole-single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a channel on-resistance of 60 Ω and operates with split supplies from ±5V to ±20V or a single positive supply from +5V to +30V. The device provides fast switching speeds with a turn-on time under 120ns and a turn-off time under 90ns. It supports a maximum breakdown voltage of 44V, enabling 30V peak-to-peak switch-off blocking capacity. The component utilizes CMOS logic-compatible inputs for reduced loading and low leakage currents. It is housed in a 16-pin Narrow SO package and functions within an operating temperature range of 0°C to +70°C.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the package type and temperature rating. The 'CY' designation indicates a 16-pin Narrow SOIC package with a commercial operating temperature range of 0°C to +70°C. Ensure compatibility with system voltage requirements and signal levels before procurement.

Selection Notes

Select this component for applications requiring normally closed SPST switching with low on-resistance. Verify that the required analog signal range fits within the specified supply voltages. Consider the package constraints and thermal dissipation limits when designing the PCB layout for high-density applications.

Part Context

This part belongs to the DG308A/DG309 family of quad SPST analog switches. While the DG308A is normally open, the DG309 variant is specifically designed as a normally closed switch. Both share identical electrical characteristics regarding speed, resistance, and power consumption, differing only in their default state configuration.

FAQ

What is the default state of the DG309CY switch?

The DG309CY is a normally closed (NC) SPST analog switch, meaning the channels are conductive when the logic input is low.

Can the DG309CY operate with a single supply?

Yes, it can operate with a single positive supply ranging from +5V to +30V, though switching speed may be slower compared to bipolar supply operation.
