DESCRIPTION
The HCC/HCF40147B CMOS encoder features
priority encoding of the inputs to ensure that only the
highest order data line is encoded. Ten data input
lines (0-9) are encoded to four line (8, 4, 2, 1) BCD.
The highest priority line is line 9. All four output 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 the
T54/T74LS147 if pin 15 is tied low.
The HCC/HCF40147B types are supplied in 16 lead
plastic or ceramic and plastic micropackage.
