Description
The ’HC147 and CD74HCT147 are high speed silicon-gate
CMOS devices and are pin-compatible with low power
Schottky TTL (LSTTL).
The ’HC147 and CD74HCT147 9-input priority encoders
accept data from nine active LOW inputs (l

CD54HC147, CD74HC147,
provide binary representation on the four active LOW inputs
(Y0 to Y3). A priority is assigned to each input so that when
two or more inputs are simultaneously active, the input with
the highest priority is represented on the output, with input
= 5V,

having the highest priority.

These devices provide the 10-line to 4-line priority encoding
function by use of the implied decimal “zero”. The “zero” is
encoded when all nine data inputs are HIGH, forcing all four
outputs HIGH.
