The 74ALS240A1 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 74ALS240A1 sinks 48 mA IOL if the VCC is limited to 5.0V ±0.25V.
