DG884DN-E3

Analog Switches - Special Purpose Overview

The DG884DN-E3 is a wideband video crosspoint array manufactured by Vishay Siliconix, housed in a 44-pin PLCC package. It features an 8 x 4 matrix of T-switches capable of routing any input to any output simultaneously. The device operates on dual supplies ranging from -5 V to 0 V for the negative rail and 10 V to 20 V for the positive rail, with a logic supply typically at 5 V. Key electrical parameters include a bandwidth of 300 MHz, a maximum on-resistance of 90 Ω, and adjacent input crosstalk of -85 dB at 5 MHz. Transition times are specified at 300 ns, with turn-on and turn-off times reaching 500 ns and 300 ns respectively under full temperature conditions.

Analog Switches - Special Purpose Feature Summary

• Configures an 8 x 4 crosspoint matrix using low capacitance DMOS FETs for high-speed signal routing.
• Incorporates double-buffered TTL-compatible latches with readback capabilities for status monitoring.
• Features open-drain disable outputs to control external buffers or place unused channels in standby mode.
• Utilizes ground lines between adjacent signal pins to minimize crosstalk and improve off-isolation.

Analog Switches - Special Purpose Applications

• Wideband signal routing and multiplexing
• High-end video systems including NTSC, PAL, and SECAM switchers
• Digital video routing matrices
• Automated Test Equipment (ATE) systems

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the E3 suffix. Check current lifecycle status, as this part may be subject to discontinuation or obsolescence notices. Ensure proper handling procedures are followed due to the sensitivity of CMOS control logic.

Analog Switches - Special Purpose Selection Notes

Select this component when a monolithic 8 x 4 crosspoint solution is required for video or wideband signals. Consider the PLCC-44 package constraints and the need for dual power supplies if bipolar signal swings are necessary. Evaluate the 300 MHz bandwidth against system requirements and ensure thermal management supports the specified power dissipation limits within the operating temperature range.

Analog Switches - Special Purpose Part Context

This device belongs to the DG884 family of wideband video crosspoint arrays produced by Vishay Siliconix. It represents a monolithic integration of switching elements designed to replace discrete transistor matrices. The DN suffix indicates the specific plastic leaded chip carrier package variant compliant with environmental directives.
