DESCRIPTION

The DG506B and DG507B are high performance analog

multiplexers. Their ultra-low switch charge injection, low

channel capacitance, and low leakage level allows them to

achieve superior switching performance. The DG506B is a

16-channel single-ended analog multiplexer designed to

connect one of sixteen inputs to a common output as

determined by a 4-bit binary address (A0, A1, A2, A3). The

DG507B is a dual 8-channel differential analog multiplexer

designed to connect one of eight differential inputs to a

common dual output as determined by its 3-bit binary

address (A0, A1, A2). Break-before-make switching action

protects against momentary crosstalk between adjacent

channels.

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, addresses

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

specified operating temperature range.

The DG506B and DG507B are fabricated on an enhanced

SG-II CMOS process that achieves improved performance

on: reduced charge injection, lower device leakage, and

minimized parasitic capacitance.

As the DG506, DG507 has a long history in the industry with

many suppliers offering copies, and in some cases improved

variations, with the best in class improvements, the Vishay

Siliconix new version of the DG506B, DG507B are the

superior alternatives to what is currently available.

Applications for the DG506B, DG507B include high speed

and high precision 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.

The DG506B and DG507B have the absolute maximum

voltage rating extended to 44 V. Additionally, single supply

operation is also allowed. An epitaxial layer prevents

latch-up.

The DG506B and DG507B are both available in 28-lead

SOIC and TSSOP package options with extended

temperature range of -40 °C to +125 °C.
