APPLICATIONS:
The
HCC/HCF40147B
CMOS encoder features
priority encoding ofthe inputstoensure thatonlythe
highest order data line is encoded. Ten data input
lines (0-9) are encoded to four line (8, 4, 2, 1) BCD.
The highestpriority line isline 9.Allfouroutput lines
are logic 1 (VSS) when all input lines are logic 0.All
inputs and outputs are buffered, and each output
can drive one TTL Low Power Schottky load. The
HCC/HCFF40147
is functionally similar to
T54/T74LS147 if pin 15 is tied low.
The
HCC/HCF40147B
types aresupplied in16lead
