10- to 4-Line Priority Encoder

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

• Buffered Inputs and Outputs

• Typical Propagation Delay: 13ns at V

= 5V,

line l having the highest priority.

C = 15pF, T = 25 C

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.

The ’HC147 and CD74HCT147 are high speed silicon-gate

CMOS devices and are pin-compatible with low power

Schottky TTL (LSTTL).

NOTE: When ordering, use the entire part number. The sufﬁxes

96 and R denote tape and reel. The sufﬁx T denotes a

small-quantity reel of 250.

The ’HC147 and CD74HCT147 9-input priority encoders

accept data from nine active LOW inputs (l to l ) and
