DM74ALS253
3-STATE Dual 1-of-4 Line Data Selector/Multiplexer
General Description
This Data Selector/Multiplexer contains full on-chip decod-
ing to select one-of-four data sources as a result of a
unique two-bit binary code at the Select Inputs. Each of the
two Data Selector/Multiplexer circuits have their own sepa-
rate Data and Output Control inputs and a non-inverting 3-
STATE output buffer. The Output Control inputs, when at
the high level, place the corresponding output in the high
impedance OFF-State. In order to prevent bus access con-
flicts, 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.
Features
s Advanced oxide-isolated, ion-implanted Schottky TTL
process
s Switching performance is guaranteed over full tempera-
ture and VCC supply range
s Pin and functional compatible with LS family counterpart
s Improved output transient handling capability
s Output control circuitry incorporates power-up 3-STATE
feature
