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.
