Description

CD40147BMS 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 CD40147BMS is func-

tionally similar to the TTL 54/74147 if pin 15 is tied low.

The CD40147BMS is supplied in these 16-lead outline

packages:

Braze Seal DIP

Frit Seal DIP

Ceramic Flatpack

H4T

H1E

H6W

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
