Vishay Siliconix
Precision 16-Channel/Dual 8-Channel CMOS Analog Multiplexers
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.
