DG309CJ

Overview

The DG309CJ is a quad, single-pole-single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features normally closed contacts and operates with split supplies ranging from ±5V to ±20V or a single positive supply from +5V to +30V. The device provides a typical channel on-resistance of 60 Ω, with a maximum rating of 100 Ω. Switching performance includes a turn-on time under 130 ns and a turn-off time under 90 ns. It utilizes CMOS logic-compatible inputs for reduced loading and low leakage currents.

Feature Summary

Monolithic low-power CMOS design
CMOS logic compatible inputs
Single or bipolar supply operation

Applications

Sample-and-Hold Circuits
Test Equipment
Communications Systems
PBX, PABX
Guidance and Control Systems

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm package type and temperature range. The standard CJ suffix indicates a plastic DIP package with an operating temperature range of 0°C to +70°C. Confirm RoHS compliance status as older manufacturing runs may differ from current specifications.

Selection Notes

Select this component when a normally closed SPST configuration is required for signal routing. Ensure the application voltage does not exceed the 44V breakdown rating. Verify that the 60 Ω on-resistance meets system impedance requirements. Consider the DG308A if a normally open configuration is needed instead.

Part Context

This part belongs to the DG308A/DG309 family of quad SPST analog switches. The DG309 variant specifically provides normally closed contacts, whereas the DG308A provides normally open contacts. Both share identical electrical characteristics and pinouts, differing only in their default contact state.
