Overview
The DG308BDJ-E3 is a quad single-pole single-throw (SPST) analog switch manufactured by Vishay Siliconix. It operates within a supply voltage range of ±4 V to ±22 V, with a maximum power dissipation of 470 mW in the 16-pin PDIP package. The device features a maximum on-resistance of 85 Ω and supports a maximum switching current of 30 mA. Dynamic performance includes a turn-on time of 200 ns and a turn-off time of 150 ns. It functions across an operating temperature range from -40 °C to +85 °C.
Feature Summary
- CMOS compatible logic interface for simple integration
- Improved charge injection compensation design minimizes switching transients
- Epitaxial layer prevents latchup for enhanced reliability
Applications
- Industrial instrumentation
- Test equipment
- Sample-and-hold circuits
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure storage conditions adhere to specified humidity sensitivity levels to maintain device integrity during handling and assembly processes.
Selection Notes
Select this part when a normally open configuration is required for signal routing. Compare against the DG309B variant if a normally closed state is needed instead. Verify that the 85 Ω on-resistance meets system accuracy requirements and confirm that the PDIP-16 package dimensions fit the target PCB layout constraints.
Part Context
This component belongs to the DG308B series, representing an improved version of the industry-standard DG308A. It utilizes Vishay's proprietary silicon gate CMOS process to achieve lower on-resistance and leakage compared to previous generations. The 'E3' suffix indicates lead-free terminations compliant with RoHS directives.

FAQ
What is the default state of the DG308BDJ-E3 switches?
The DG308BDJ-E3 consists of four normally open switches. The contacts close when the input logic is high and remain open when the input logic is low.
How does the DG308BDJ-E3 handle signals exceeding supply rails?
Signals on source or drain pins exceeding the positive or negative supply voltages will be clamped by internal diodes. Designers must limit forward diode current to maximum ratings to prevent damage.
