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 16lead

plastic or ceramic and plastic micropackage.
