INTEGRATED CIRCUITS 74F240/74F240A Octal inverter buffer (3-State) 74F241/74F241A Octal buffer (3-State) Product specification IC15 Data Handbook 1001 Jan 02 Philips Semiconductors Philips Semiconductors Product specification Buffers 74F240/74F240A/ 74F241/74F241A FEATURES Octal bus interface 3-State buffer outputs sink 64mA 15mA source current Guaranteed output skew less than 2.0ns (74F240A/74F241A) Reduced ground bounce (74F240A/74F241A) DESCRIPTION The 74F240 and 74F241 are octal buffers that are ideal for driving bus lines of buffer memory address registers. The outputs are all capable of sinking 64mA and sourcing up to 15mA. The device features two output enables, each controlling four of the 3–state outputs. The 74F240A and 74F241A are functionally equivalent to their non–A counterparts. They have been designed to reduce effects of ground noise. Other advantages are noted in the features.
