3-STATE 1-of-8 Line Data Selector/Multiplexer
General Description
This Data Selector/Multiplexer contains full on-chip decod-
ing to select one-of-eight data sources as a result of a
unique three-bit binary code at the Select inputs. Two com-
plementary outputs provide both inverting and non-invert-
ing buffer operation. An Output Control input is provided
which, when at the high level, places both outputs in the
high impedance OFF-State. In order to prevent bus access
conflicts, output disable times are shorter than output
enable times. The Select input buffers incorporate internal
overlap features to ensure that select input changes do not
cause invalid output transients.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
