DG309BDJ

Overview

The DG309BDJ is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix in a 16-pin plastic DIP package. It operates with dual supplies ranging from ±4 V to ±22 V or a single supply up to 44 V. The device features a maximum on-resistance of 85 Ω at room temperature and 100 Ω across the full industrial temperature range (-40 °C to +85 °C). Key electrical parameters include a turn-on time of 200 ns, turn-off time of 150 ns, and charge injection of 1 pC. Supply current is limited to 5 µA maximum.

Feature Summary

Normally closed configuration where the switch connects the signal path when the logic input is low.
CMOS compatible logic interface requiring minimal drive current for control signals.
Epitaxial layer construction prevents latch-up during high-voltage transient events.
Improved charge injection compensation design minimizes switching transients.

Applications

Sample-and-hold circuits
Industrial instrumentation
Test equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'DJ' corresponds to the 16-pin plastic DIP package variant. Check RoHS compliance status if lead-free terminations are required for the assembly process. Ensure the ordering part number matches the exact voltage and temperature specifications needed for the target application environment.

Selection Notes

Select this component when a normally closed analog switch topology is required for the circuit design. Verify that the maximum on-resistance of 85 Ω meets the signal integrity requirements. Ensure the operating voltage does not exceed the ±22 V absolute maximum rating. Consider the PDIP-16 package dimensions for PCB layout constraints compared to surface-mount alternatives.

Part Context

This device belongs to the DG308B/DG309B series of improved quad CMOS analog switches. It serves as the normally closed counterpart to the DG308BDJ, which is normally open. Both devices share identical pinouts and electrical characteristics except for the logic state required to activate the switch channel.
