FEATURES
Octal bus interface
3-state buffer outputs sink 64 mA
15 mA source current
TYPE
74F241
TYPICAL PROPAGATION DELAY
4.0 ns
DESCRIPTION
The 74F241 is an octal buffer that is ideal for driving bus lines of
buffer memory address registers. The outputs are all capable of
sinking 64 mA and sourcing up to 15 mA. The device features two
output enables, each controlling four of the 3-state outputs.
