3-STATE Dual 1 of 4 Line Data Selector/Multiplexer
DM74ALS253 3-STATE Dual 1-of-4 Line Data Selector/Multiplexer April 1984 Revised February 2000 DM74ALS253 3-STATE Dual 1-of-4 Line Data Selector/Multiplexer General Description Features This Data Selector/Multiplexer contains full on-chip decod- � Advanced oxide-isolated, ion-implanted Schottky TTL ing to select one-of-four data sources as a result of a process unique two-bit binary code at the Select Inputs. Each of the � Switching performance is guaranteed over full tempera- two Data Selector/Multiplexer circuits have their own sepa- ture and V supply range CC rate Data and Output Control inputs and a non-inverting 3- � Pin and functional compatible with LS family counterpart STATE output buffer. The Output Control inputs, when at � Improved output transient handling capability the high level, place the corresponding output in the high impedance OFF-State. In order to prevent bus access con- � Output control circuitry incorporates power-up 3-STATE flicts, output disable times are shorter than output enable feature times. The Select input buffers incorporate internal overlap features to ensure that select input changes do not cause invalid output transients.
