DG407BDN-T1

Analog Switches, Multiplexers, Demultiplexers Overview

The DG407BDN-T1 is a dual 8-channel high-performance CMOS analog multiplexer manufactured by Vishay Siliconix. It selects one of eight differential inputs to a common differential output using a 4-bit binary address. The device operates within a temperature range of -40 °C to +85 °C and utilizes a 28-pin PLCC package. Key electrical specifications include a maximum on-resistance of 74 Ω, a transition time of up to 161 ns, and an off-isolation of -86 dB at 1 MHz. It supports single supply voltages from 5 V to 40 V or dual supplies from ±5 V to ±20 V.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the purpose of the break-before-make switching action?

It protects against momentary shorting of inputs by ensuring the current path is fully disconnected before a new connection is established.

How does the Enable (EN) pin function?

The EN input allows the user to reset the multiplexer to all switches off, which facilitates the stacking of several devices on a common bus.

Is the device suitable for single-supply operation?

Yes, the DG407B supports single supply operation ranging from 5 V to 40 V, in addition to dual supply configurations.
