74F540集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

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.

FEATURES

• High impedance NPN base inputs for reduced loading (20µA 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
