may be AC or DC coupled. AC coupling is recommended because the input circuit provides its own bias. (See Figure below)
TL/W/11766–15
Proper use of grounds and bypass capacitors is essential to achieve a high level of performance.
Crosstalk between pins can be reduced by careful board layout.
This is a static sensitive device. It should be handled only at static free work stations.
