April 1984 Revised February 2000
DM74ALS253 3-STATE Dual 1-of-4 Line Data Selector/Multiplexer
General Description
This Data Selector/Multiplexer contains full on-chip decoding 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 separate Data and Output Control inputs and a non-inverting 3STATE 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 conflicts, output disable times are shorter than output enable t...
