Data sheet acquired from Harris Semiconductor
SCHS102C − Revised October 2003
The CD40147B 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 CD40147B is
functionally similar to the TTL54/74147 if pin 15
is tied low.
The CD40147B types are supplied in 16-lead
dual-in-line plastic packages (E suffix), 16-lead
small-outline packages (M, M96, MT, and NSR
suffixes), and 16-lead thin shrink small-outline
packages (PW and PWR suffixes).

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
