DESCRIPT ION

The HCC/HCF40147B CMOS encoder features
priority encodingoftheinputstoensure thatonlythe
highest order data line is encoded. Ten data input
lines (0-9) are encoded to fourline (8, 4, 2, 1) BCD.
The highestpriority lineisline 9.Allfouroutputlines
arelogic 1 (VSS) when all input lines are logic0.All
inputs and outputs are buffered, and each output
can drive one TTL Low Power Schottky load. The
HCC/HCFF40147 is functionally similar to the
T54/T74LS147 if pin 15 istied low.

TheHCC/HCF40147B typesaresupplied in16lead
plasticor ceramic andplastic micropackage.
