FEATURES
DESCRIPTION
The 74F540 and 74F541 are octal buffers that are ideal for driving
bus lines or buffer memory address registers. The outputs are
capable of sinking 64mA and sourcing up to 15mA, producing very
good capacitive drive characteristics. The devices feature input and
outputs on opposite sides of the package to facilitate printed circuit
board layout.
INPUT AND OUTPUT LOADING AND FAN-OUT TABLE
NOTE: One (1.0) FAST Unit Load is defined as: 20 A in the High state and 0.6mA in the Low state.
