74ALS241A

INTEGRATED CIRCUITS 74ALS241A/74ALS241A–1 Octal buffer (3–state) Product specification IC05 Data Handbook 1991 Feb 08 Philips Semiconductors Philips Semiconductors Product specification Octal buffer (3-State) 74ALS241A/74ALS241A-1 FEATURES Octal bus interface 3-State buffer outputs sink 24mA and source 15mA The -1 version sinks 48 mA DESCRIPTION The 74ALS241A 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 74ALS241A-1 sinks 48mA IOL if the VCC is limited to 5.0V ±0.25V.
