3-LINE TO 8-LINE DECODERS/DEMULTIPLEXERS
SCLS107E DECEMBER 1982 REVISED SEPTEMBER 2003

POST OFFICE BOX 655303
DALLAS, TEXAS 75265
description/ordering information (continued)
The conditions at the binary-select inputs at the three enable inputs select one of eight output lines. Two
active-low and one active-high enable inputs reduce the need for external gates or inverters when expanding.
A 24-line decoder can be implemented without external inverters, and a 32-line decoder requires only one
inverter. An enable input can be used as a data input for demultiplexing applications.
