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.

Each of these DM74S253 Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary, on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections.

The 3-STATE outputs can interface directly with data lines of bus-organized systems. With all but one of the common outputs of DM74S253 disabled (at a high impedance state), the low impedance of the single enable output will drive the bus line to a HIGH or LOW logic level.
