Details

TI 74ALS244BN OCTAL BUS DRIVER The an octal buffer that is ideal for driving bus lines or buffer memory address registers. The outputs are all capable of sinking 24mA and sourcing to 15mA, producing very good capacitive drive characteristics. The device features two output enables, OEa and OEb, each controlling four of the 3-State outputs. The 74ALS244A-1 sinks 48 mA IOL if the VCC is limited 5.0V ±0.25V. TYPICAL PROPAGATION DELAY 4.5ns TYPICAL SUPPLY CURRENT (TOTAL) 17mA

These octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmit- ters. Taken together with the ’ALS240A, ’ALS241A, ’AS240, and ’AS241, these devices provide the choice of selected combinations of inverting outputs, symmetrical G (active-low input control) inputs, and complementary G and G inputs.
