A11143S - 74ALS153M SMD Dual Data Selector/Multiplexer (National)

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 Strobe inputs and a non-inverting output buffer. The Select inputs A and B are common to both sections. The Strobe inputs, when at the HIGH level, disable their associated data inputs and force the corresponding output to the LOW state. The Select input buffers incorporate internal overlap features to ensure that select input changes do not cause invalid output transients.

Features:
Advanced oxide-isolated, ion-implanted Schottky TTL process
Switching performance is guaranteed over full temperature and VCC supply range
Pin and functional compatible with LS family counterpart
Improved output transient handling capability

SOIC 16 package. Manufactured by National.
