Note 1:  The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.The "Recommended Operating Conditions" table will define the conditions for actual device operation.

  These DM74ALS157 data selectors/multiplexers contain inverters and drivers to supply full on-chip data selection to the four out-put gates. A separate strobe input is provided. A 4-bit word is selected from one of two sources and is routed to the four outputs. The DM74ALS157 presents true data whereas the ALS158 presents inverted data to minimize propagation delay time.
