DESCRIPTION
The DG508B 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 DG509B 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.
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 DG508B and DG509B 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 DG508, DG509 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 DG508B, DG509B
are the superior alternatives to what is currently available.
Applications for the DG508B, DG509B 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 DG508B and DG509B have the absolute maximum
voltage rating extended to 44 V. Additionally, single supply
operation is also allowed. An epitaxial layer prevents
latch-up.
The DG508B and DG509B are both available in 16-lead
SOIC and TSSOP package options with extended
temperature range of - 40 °C to + 125 °C.
For more information, refer to Vishay Siliconix DG508B,
DG509B evaluation board note.
