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

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

-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
