highest order data line is encoded. Ten data input

lines (0-9) are encoded to four line (8, 4, 2, 1)

BCDs. The highest priority line is line 9. All four

output lines are logic "1" (V ) when all input lines

are logic "0". All inputs and outputs are buffered,

and each output can drive one TTL Low Power

Schottky load. HCF40147B is functionally similar

to the T54/T74LS147 if pin 15 is tied low.

HCF40147B is supplied in 16-lead plastic or

ceramic and plastic micropackages.

DESCRIPTION

HCF40147B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

HCF40147B, encoder CMOS, features priority

encoding of the inputs to ensure that only the
