DESCRIPTION
The DG406B 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
DG407B 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 DG406B, DG407B 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.
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.
