DG308BDJ

Overview

The DG308BDJ is a quad single-pole single-throw (SPST) CMOS 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 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 1 µA typical, supporting low-power applications.

Feature Summary

CMOS fabrication process for low power consumption and high speed
Improved charge injection compensation design minimizes switching transients
Epitaxial layer prevents latchup for reliable operation
True bi-directional signal performance in the on condition

Applications

Industrial instrumentation
Test equipment
Communications systems
Sample-and-hold circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm package type and compliance status. The base part number DG308B indicates the functional variant, while suffixes such as DJ define the physical package. Confirm availability through authorized distributors as manufacturing status may vary. Ensure the selected component matches the required operating temperature range and pin configuration for the target circuit design.

Selection Notes

Select the DG308BDJ when a normally open quad SPST configuration is required with low on-resistance and fast switching speeds. Compare the 85 Ω on-resistance and 200 ns switching times against system requirements. Consider the 16-pin PDIP package constraints for PCB layout. Evaluate the ±22 V supply rating to ensure compatibility with the analog signal voltage range and logic interface levels used in the application.

Part Context

The DG308BDJ belongs to the DG308B/DG309B series of improved quad CMOS analog switches. These devices are enhanced versions of the industry-standard DG308A and DG309, offering lower on-resistance, reduced leakage, and higher speed. The series utilizes Vishay Siliconix’s proprietary silicon gate CMOS process to achieve superior performance characteristics compared to previous generations.
