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.  
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 maximumvoltage  
rating is extended to 44 V. Additionally, single supply operation  
is also allowed and an epitaxial layer prevents latchup.  
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  
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.
