Description
The DG428/DG429 analog multiplexers have on-chip
address and control latches to simplify design in
microprocessor based applications. Break-before-make
switching action protects against momentary crosstalk of
adjacent input signals.
The DG428 selects one of eight single-ended inputs to a
common output, while the DG429 selects one of four
differential inputs to a common differential output.
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 silicon-gate CMOS process enables operation over a
wide range of supply voltages. The absolute maximum
voltage rating is extended to 44 V. Additionally, single
supply operation is also allowed and an epitaxial layer
prevents latchup.
On-board TTL-compatible address latches simplify the
digital interface design and reduce board space in
bus-controlled systems such as data acquisition systems,
process controls, avionics, and ATE.
