Vishay Siliconix

8-Ch/Dual 4-Ch High-Performance CMOS Analog Multiplexers

DESCRIPTION

FEATURES

•

Low On-Resistance - r_DS(on): 100 Ω

Low Charge Injection - Q: 20 pC

Fast Transition Time - t_TRANS: 160 ns

Low Power - I_SUPPLY: 10 µA

Single Supply Capability

The DG408 is an 8-channel single-ended analog multiplexer

designed to connect one of eight inputs to a common output

as determined by a 3-bit binary address (A₀, A₁, A₂). The

DG409 is a dual 4-channel differential analog multiplexer

designed to connect one of four differential inputs to a

common dual output as determined by its 2-bit binary

address (A₀, A₁). Break-before-make switching action

protects against momentary crosstalk between adjacent

channels.

Pb-free

Available

RoHS*

COMPLIANT

44 V Supply Max Rating

TTL Compatible Logic

An on channel conducts current equally well in both

directions. In the off state each channel blocks voltages up

to the power supply rails. An enable (EN) function allows the

user to reset the multiplexer/demultiplexer to all switches off

for stacking several devices. All control inputs, address (A_x)

and enable (EN) are TTL compatible over the full specified

operating temperature range.

BENEFITS

•

Reduced Switching Errors

Reduced Glitching

Improved Data Throughput

Reduced Power Consumption

Increased Ruggedness

Wide Supply Ranges ( 5 V to 20 V)

Applications for the DG408/409 include high speed data

acquisition, audio signal switching and routing, ATE

systems, and avionics. High performance and low power

dissipation make them ideal for battery operated and remote

instrumentation applications.

APPLICATIONS

•

Data Acquisition Systems

Audio Signal Routing

ATE Systems

Battery Powered Systems

High Rel Systems

Designed in the 44 V silicon-gate CMOS process, the

absolute maximum voltage rating is extended to 44 V.

Additionally, single supply operation is also allowed. An

epitaxial layer prevents latchup.

APPLICATIONS HINTS

Overvoltage Protection

A very convenient form of overvoltage protection consists of

adding two small signal diodes (1N4148, 1N914 type) in

series with the supply pins (see Figure 10). This

arrangement effectively blocks the flow of reverse currents.

It also floats the supply pin above or below the normal V+ or

V- value. In this case the overvoltage signal actually

becomes the power supply of the IC. From the point of view

of the chip, nothing has changed, as long as the difference

VS - (V-) doesn’t exceed + 44 V. The addition of these diodes

will reduce the analog signal range to 1 V below V+ and 1 V

above V-, but it preserves the low channel resistance and low

leakage characteristics.
