Note 2: 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.

This four data line transceiver,DM74LS243 is designed for asynchronous two-way communications between data buses. It can be used to drive terminated lines down to 133.
