Buffers 74F540, 74F541
74F540 Octal Inverter Buffer (3-State)
74F541 Octal Buffer (3-State)

FEATURES
• High impedance NPN base inputs for reduced loading
(20mA in High and Low states)
• Low power, light bus loading
• Functionally similar to the 74F240 and 74F241
• Provides ideal interface and increases fan-out of MOS
microprocessors
• Efficient pinout to facilitate PC board layout
• Octal bus interface
• 3-State buffer outputs sink 64mA
• 15mA source current

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.
