Description
The DG406 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. The DG407
selects one of eight differential inputs to a common
differential output. Break-before-make switching action
protects against momentary shorting of inputs.
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.
Applications for the DG406/407 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. For additional application
information, see application note AN206.
Designed in the 44-V silicon-gate CMOS process, the
absolute maximum voltage rating is extended to 44 volts,
allowing operation with
"20-V
supplies. Additionally
single (12-V) supply operation is allowed. An epitaxial layer
prevents latchup.
