DG308BDQ-E3

Overview

The DG308BDQ-E3 is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Vishay Siliconix. It operates within a dual supply voltage range of ±4 V to ±22 V or a single supply of 4 V to 44 V. The device features a maximum on-resistance of 85 Ω at room temperature and up to 100 Ω across the full operating temperature range of -40 °C to +85 °C. Key dynamic parameters include a turn-on time of 200 ns, a turn-off time of 150 ns, and charge injection of 1 pC. It is housed in a 16-pin TSSOP package with a power dissipation rating of 640 mW.

Feature Summary

CMOS fabrication process enabling low leakage currents and minimal power consumption
Improved charge injection compensation design for reduced switching transients
Epitaxial layer construction preventing latchup under high signal conditions
True bi-directional signal handling capability in the on state

Applications

Industrial instrumentation systems
Test equipment signal routing
Sample-and-hold circuits
Communications systems
Computer peripherals

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official datasheets. Check for discontinuance notifications as availability may be restricted. Validate package markings against the specific TSSOP-16 configuration. Ensure storage and handling procedures meet ESD protection standards.

Selection Notes

Select this component when designing circuits requiring quad SPST switching with extended voltage capabilities up to ±22 V. Consider the 85 Ω on-resistance limit for signal integrity requirements. Verify that the TSSOP-16 footprint aligns with PCB layout constraints. Evaluate thermal management needs based on the 640 mW power dissipation rating in the target enclosure.

Part Context

This part belongs to the DG308B series, representing an improved version of the industry-standard DG308A. It shares functional similarities with the DG309B but differs in logic states, offering normally open operation. The suffix 'E3' indicates lead-free packaging compliant with environmental directives. The 'DQ' suffix specifically denotes the 16-lead Thin Shrink Small Outline Package.
