8-Ch / Dual 4-Ch High Performance Analog Multiplexers
DESCRIPTION
The DG408LE, DG409LE are monolithic analog
multiplexers / demultiplexers designed to operate on
single and dual supplies. Single supply voltage ranges from
3 V to 16 V while dual supply operation is recommended
with ± 3 V to ± 8 V.
The DG408LE 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
(A
0
, A
1
, A
2
). The DG409LE 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 (A
0
, A
1
). Break-before-make
switching action to protect 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, address
(Ax) and enable (EN) are TTL compatible over the full
specified operating temperature range.
The DG408LE, DG409LE feature low on-resistance, fast
switching time, and low leakage. They are ideal for data
acquisition, control and automation, test instrument, and
healthcare products. The DG408LE, DG409LE has an
internal regulator powers the logic circuit. Such design
reduces device power consumption and makes them ideal
for battery operated applications.
The DG408LE, DG409LE are available in TSSOP16,
SOIC16, and QFN16 packages.
