ADVANTAGES
Space and weight savings
* Simple mounting
' Improved temperature and power
cycling
Reduced protection circuits
HD74ALVC16835TEL   price 

After conversion of all 8 channels the results are storaged
in the result RAM. After ending the conversion of channel 7
the output INT becomes active (low ). This output can be
used to trigger a microcontroller with interrupt or DMA
request.
