Description

The 74ALS244A is 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 up 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 I_OL if the V_CC is limited to 5.0V ±0.25V.
