DG536DN

Analog Switches - Special Purpose Overview

The DG536DN is a 16-channel wideband video multiplexer manufactured by Vishay Siliconix. It routes one of sixteen analog or digital input signals to a single output using n-channel DMOS switches. The device operates on a single supply voltage ranging from 10 V to 16.5 V, with a maximum power dissipation of 450 mW in the PLCC-44 package. Key electrical parameters include a bandwidth of 500 MHz, an on-resistance (rDS(on)) of up to 90 Ω, and a switching time of 300 ns. It features low crosstalk (-100 dB at 5 MHz) and includes on-chip address latches for simplified microprocessor interfacing.

Analog Switches - Special Purpose Feature Summary

• Integrates on-chip address latches and decode logic to simplify bus interface requirements.
• Utilizes n-channel DMOS 'T' switches to achieve wide bandwidth and high off-isolation.
• Provides break-before-make switching to prevent momentary shorting during channel transitions.
• Features a disable output pin that sinks current when any channel is selected.

Analog Switches - Special Purpose Applications

• Video switching and routing
• High-speed data routing
• RF signal multiplexing
• Precision data acquisition systems
• Crosspoint arrays

Analog Switches - Special Purpose Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as standard versions may contain lead. Ensure proper handling procedures are followed due to the sensitivity of CMOS logic inputs. Review the datasheet for absolute maximum ratings to prevent damage during installation.

Analog Switches - Special Purpose Selection Notes

Select this component for applications requiring high channel count and wide bandwidth. Verify that the system supply voltage falls within the 10 V to 16.5 V range. Consider the PLCC-44 package constraints for PCB layout. Evaluate thermal dissipation requirements if operating near maximum temperature limits.

Analog Switches - Special Purpose Part Context

The DG536DN belongs to the DG535/536 family of 16-channel wideband video multiplexers. It shares functional similarities with the DG535 but differs in package configuration. This series is designed for high-performance signal routing where low crosstalk and fast switching speeds are critical requirements.

Analog Switches - Special Purpose FAQ

What is the function of the DIS pin?

The DIS pin is an open-drain output that provides a low impedance connection to ground when any channel is selected, and remains high impedance when no channel is selected.

How does the device handle negative input signals?

Negative signals relative to ground can forward bias the PN junction between the substrate and source/drain terminals. DC biasing is recommended to avoid distortion or excessive current flow.

What is the purpose of the ST input?

The Strobe (ST) input controls the on-chip address latches. When ST goes low, it latches the binary address present on inputs A0-A3, selecting the corresponding channel.
